How to deal with solder balls at the arc end 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.

2. Undercut

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.

3. Stomata

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.

What are the precautions for the use of tank welding machine?

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.

What are the working steps of tank welding machine?

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.

What is the operation process of the simple chain type hydraulic jacking system?

LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.

What is the working principle of the simple chain type hydraulic jacking system?

LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

What are the advantages of simple chain type hydraulic jacking system?

1. Simple chain type hydraulic jacking system is stable, safe and reliable. Due to the adoption of unified hydraulic control and single or partial (several) adjustment, the whole lifting process is relatively stable. The hoist is provided with synchronizing valve and hydraulic lock to prevent sliding and falling of the tank or heavy loads, which are caused by power failure and fracture of oil tube. Hydraulic lifting is stable, safe and reliable.

2. Construction quality is ensured. As the hoist is provided with synchronizer and adjustable function, lifting height can be controlled accurately. Due to above reasons, quality of the tank is ensured.

What are the precautions for the use of plasma and flame cutting machine?

1. Points to be paid attention to in forging cutting

Due to the thicker oxide scale on the surface of the forging and the fact that the ignition point of the oxide scale is higher than the melting point, the plasma and flame cutting machine is prone to cutting interruption during cutting, resulting in reduced cutting quality and reduced work efficiency. For this reason, when the forging is cut, the oxide scale on the upper and lower surfaces of the cutting area should be removed before cutting to improve the cutting speed and cutting quality.

2. The main points of anti-deformation in rolling billet cooling bed tooth plate cutting

How to control the deformation of the workpiece during cutting is very important. For example, arranging the cutting route according to the routine will cause the workpiece to be deformed and out of tolerance. Even if it is reshaped, it is difficult to meet the size requirements, and the product will eventually be scrapped. Therefore, it is very important to arrange the gas cutting route of the plasma and flame cutting machine reasonably.

3. Points to be paid attention to in thick plate cutting

In thick steel plate cutting, the temperature decreases from the top surface down. At the beginning of cutting by plasma and flame cutting machine, the oxygen pressure is gradually increased, and finally reaches a uniformity in the thickness direction of the steel plate. This results in inconsistent combustion in the thickness direction of the steel plate at the starting position of cutting, and defects at the starting end of the workpiece cutting.

Compared with similar products, what are the characteristics of plasma and flame cutting machine?

Compared with laser cutting: plasma and flame cutting machine is far less than laser cutting machine in terms of cutting speed accuracy and cutting material types, but it is better than laser cutting machine in cutting thickness and cutting cost.
