Tank welding machines are actually transformers with lower external characteristics, which convert 220V and 380V alternating current into low-voltage direct current. Electric welding machines can generally be divided into two types according to the output power source. Therefore, tank welding machines can be divided into many types according to different characteristics.
Here is the content list:
l Tank welding machines are classified according to power characteristics.
l What types of tank welding machines does WINCOO have?
l What are the classifications of tank welding machines based on the market industry?
One type of tank welding machine is AC power and the other is DC power. A DC welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power source with reduced external characteristics.
The output terminal will produce huge voltage changes when it is switched on and off the tank welding machines. When the two poles are short-circuited momentarily, the arc is ignited, and the generated arc is used to melt the electrode and welding material, and after cooling, the purpose of combining them is achieved. Welding transformers have their own characteristics. The external characteristic is the sharp drop in voltage after the electrode is ignited.

How to deal with solder balls at the arc end of tank welding machine?
What are the precautions for the use of tank welding machine?
What are the working steps of tank welding machine?
1. Welding offset
It may be that the welding position is not correct or there is a problem with the welding torch. At this time, it is necessary to consider whether the TCP (the position of the center point of the welding torch) is accurate and adjust it. If this happens frequently, check the zero position of each axis of the robot and re-calibrate to correct it.
The welding parameters may be improperly selected, the angle of the welding torch or the position of the welding torch may be incorrect, and the power can be adjusted appropriately to change the welding parameters, adjust the posture of the welding torch and the relative position of the welding torch and the workpiece.
It may be that the gas protection is poor, the primer of the workpiece is too thick or the protective gas is not dry enough, and it can be dealt with by adjusting accordingly.
4. Too much splash
It may be due to improper selection of welding parameters, gas composition or too long wire extension. We can adjust the power to change the welding parameters, adjust the gas proportioning instrument to adjust the gas mixture ratio, and adjust the relative position of the welding torch and the workpiece.
5. An arc crater is formed after cooling at the end of the weld
Add the submerged arc crater function in the work step during programming, which can be filled.
When using the tank welding machine to weld the root of the weld, start welding at the lower edge of the spot-fixed weld. Welding arc ignition by scratching method. Don't rush to weld. After the arc is ignited, preheat the starting point of the weld. The preheating has two purposes: one is to avoid the low temperature of the spot-fixed weld at the starting point and the small current used for the welding current, and the sticking phenomenon occurs, resulting in pores and leaving defects in the quality of the weld. If it is welded directly, when it is welded to the upper end joint of the spot-welding seam, the temperature of the welding seam is low, and the temperature of the welding pool cannot reach the temperature state of normal welding, which will lead to the phenomenon of impermeability or poor fusion of the welded joint, which will affect the Weld quality.
The strip material is introduced into the tank welding machine through the feeding machine, and the strip material is extruded and formed through the roller, and then arc welded with mixed gas shielded welding, rounded, output the pipe of the required length, cut by the cutter mechanism, and then straightened Straighten the machine. Spot welding machines are used for spot welding connections between tape heads. Tank welding machine is a comprehensive set of equipment that continuously welds strips into tubes, rounds and straightens them.
Against this background, do you have a deeper understanding of the tank welding machine? WINCOO ENGINEERING CO., LTD always focuses on the needs of customers and therefore offers tank welding machines and actively addresses customers to solve their problems.
The sand blasting machine uses compressed air to transport powder particles (diameter 1~4mm) from one place to another in the pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object to achieve the effect of improving the surface quality of objects.
What is the principle of sand blasting machine?
What is the workflow of sand blasting machine?
What are the advantages of sand blasting machine?
The sand blasting machine uses the grinding fluid as the feeding power of the grinding fluid, and sends the evenly stirred grinding fluid (a mixture of abrasive and water) to the spray gun through the grinding fluid pump. As the acceleration power of grinding fluid, compressed air enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding fluid entering the spray gun, and is ejected through the nozzle and sprayed onto the surface to be processed to achieve the desired processing purpose. In the liquid sandblasting machine, the grinding liquid pump is the feeding power, and the compressed air is the acceleration power.
Due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thus improving the fatigue resistance of the workpiece and increasing its adhesion between the coating and the coating prolongs the durability of the coating film. The sand blasting machine is also beneficial to the leveling and decoration of the paint, removing impurities, variegation and oxide layer on the surface, and at the same time roughening the surface of the medium, eliminating the residual stress of the workpiece and improving the surface hardness of the substrate.
1. The number and arrangement of shot blasting are calculated by computer shot blasting simulation. The 8 impellers are located up, down, left and right, respectively, to ensure that the shot blasting projectile covers most of the steel surface, including the ends. It ensures that the effect of shot blasting is comprehensive and effective.
2. The system of the sand blasting machine is a centrifugal hedging type shot blasting machine, which has the advantages of large blasting amount and fast ejection speed. The quantity and momentum of projectiles ejected to the surface of the workpiece in unit time are greatly improved. Therefore, the shot blasting time can be shortened, the efficiency can be improved, and a satisfactory cleaning quality can be achieved.
3. The dust removal system adopts filter type backwashing. The dust collector adopts a folded dust filter cartridge, which increases the dust removal area. The filter cartridge adopts nanofiber technology; the dust removal efficiency is over 99.99%, especially for dust particles with a diameter of 0.5μm. After high-efficiency filtration, the air is clean and can be recycled or discharged indoors. The pulse controller can adjust the frequency, speed and intensity of dust removal. Compared with the traditional domestic bag-type single-stage dust removal system, it has the advantages of high dust removal efficiency, small running resistance, small size, light weight and convenient replacement. Emissions comply with national emission standards.

In recent years, large-scale pipeline projects have started one after another, and the level of mechanical equipment of pipeline construction solutions has been steadily improved. However, the management of pipeline construction equipment on the construction site has not kept up with the speed of pipeline engineering and mechanical equipment updates, resulting in a high rate of equipment failure and maintenance on the construction site. High cost, low technical performance and low utilization rate. In response to these situations, explore standardized maintenance in the management of pipeline construction equipment.
Here is the content list:
l Regarding the maintenance status of pipeline construction equipment at the construction site.
l What are the specific measures to achieve standardized maintenance of pipeline construction equipment?
l How can companies ensure the effective implementation of pipeline construction equipment maintenance procedures?
l Objective conditions cause pipeline construction equipment maintenance to be unable to be carried out normally. Pipeline construction has a large geographic span, harsh construction environment, and increased equipment component wear, which directly affects the stability and reliability of the equipment, causing the mechanical equipment to lose basic performance and fail to operate normally. In addition, the current project schedule is very tight. In order to catch up with the schedule and grab the schedule, it is difficult to keep up with the daily maintenance of pipeline construction equipment.
l Subjectively neglect.The subjective factor that causes the on-site pipeline construction equipment maintenance to be unable to be carried out normally is that the relevant units and management personnel do not pay attention to the equipment management. In many construction companies, the management of the company, project management, and construction crews do not pay much attention to the management of pipeline construction equipment, believing that the equipment is just a tool for wear and tear during the construction process, which emphasizes use rather than maintenance. Many construction projects and construction units arbitrarily extend the maintenance cycle of pipeline construction equipment, reduce the grade of accessories and lubricants, so that the overhaul cycle of the engine is shortened due to human factors, project maintenance costs increase, and the cycle of equipment failures is prolonged. The technical performance of pipeline construction equipment has severely declined.
l Weak technical management capabilities.The quality of equipment maintenance has declined. First of all, many on-site management personnel's understanding of on-site maintenance of pipeline construction equipment is still at the level of "replacement of the three oil filters", and the maintenance of the engine, chassis and working devices is not included in the pipeline construction equipment. Maintenance plan in progress. Secondly, the equipment operators and maintenance personnel do not have a high level of basic skills and cannot complete the overall overhaul of pipeline construction equipment with high quality.
Repair and maintenance of pipeline construction equipmentt is very important. First of all, we must regularly check, maintain and replace vulnerable parts. WINCOO will provide manuals with the machine, such as high-performance pipeline construction equipment, automatic pipeline construction equipment, small pipeline construction equipment, high-precision pipeline construction equipment, easy-to-maintain pipeline construction equipment, etc. The following are specific measures:
① In view of the low maintenance quality of pipeline construction equipment, by compiling comprehensive, meticulous, and highly operable procedures, not only can we clarify what tasks the pipeline construction equipment operators and maintenance personnel need to do daily maintenance and secondary maintenance, but also tell them How to work.
② While compiling maintenance procedures for pipeline construction equipment, the company also compiled checklists for standardized maintenance and management of various types of pipeline construction equipment, making it the main basis for management departments at all levels to inspect pipeline construction equipment, and unify inspection standards and assessment scores. Standards to facilitate the recording, filing and review of equipment inspections and inspection results.
① Personnel training. Strengthen the learning and training of pipeline construction equipment supervisors,managers, and maintenance personnel to change their concepts, fully understand the importance of maintenance to the use of equipment, and cultivate long-term perspectives and implementation of pipeline construction equipment maintenance, and completely avoid the first phase The situation where the project "eaten" a batch of pipeline construction equipment. Through regular learning and training, the standardized equipment maintenance procedures are deeply rooted in the hearts of the people, and become the working guidelines and working habits of operators and repairers, rather than the work requirements of the superior management department. Through learning and training, to a certain extent, the sense of responsibility and dedication of managers at all levels has also been improved.
② Innovate the system of deciding people and machines. In order to mobilize the enthusiasm of equipment operators to rationally use pipeline construction equipment, earnestly maintain pipeline construction equipment, and sincerely care for pipeline construction equipment, the company strictly implements the system of determining personnel and equipment, and integrates the personnel and equipment management information system to control the attendance and equipment of the operators. The intactness of the pipeline construction equipment is linked together, and the man-hours for equipment maintenance are included in the actual man-hours of the operator.
① Increase the intensity of rewards and punishments for pipeline construction equipment inspection. In order to ensure the implementation of the standardization of pipeline construction equipment on-site maintenance, the company pays special attention to the intensity of inspection rewards and punishments for pipeline construction equipment when revising the management system.
② Link the maintenance of pipeline construction equipment with bonuses. In order to motivate the construction unit to use and maintain the pipeline construction equipment, the project department regards equipment maintenance as an important assessment index when formulating the economic responsibility system assessment, guiding the construction unit to use the maintenance pipeline construction equipment rationally, controlling the construction progress and avoiding the problem to the greatest extent.
In order to ensure that pipeline construction equipment maintenance procedures can be effectively implemented, the company has formulated corresponding management systems and adopted specific measures to supervise the implementation of these systems.
l Divide maintenance responsibilities. In the management system, the corresponding responsibilities of equipment operators, pipeline construction equipment maintenance personnel, unit equipment managers, and project pipeline construction equipment managers are clarified, and these responsibilities are written into the maintenance procedures manual of each type of equipment, so that all levels of pipeline construction equipment Managers can see what they should do every day and how to record their work in the maintenance procedures.
l Promote standardized pipeline construction equipment maintenance procedures. Implement standardized equipment maintenance organization processes in each construction project to ensure smooth equipment maintenance channels and optimize the maintenance force of the entire project.
l Establish a professional maintenance team. The project department mobilizes skilled fitters, electricians, and repairers to form a professional maintenance team, which is conducive to the unified scheduling of maintenance forces for the project, and ensures low failure rate and high utilization of pipeline construction equipment.
