In the near future, rail trains will make people's travel more convenient, safe and efficient, and the welding technology of orbital welding machine will be more closely applied in the rail train manufacturing industry.
What is the process of using the orbital welding machine?
What are the features of the orbital welding machine?
What is the using principle of the orbital welding machine?
(1) Preparation of welding parts: Considering the high hardness of the rail steel, it is difficult to process the groove on site. Therefore, the orbital welding machine adopts the docking method and uses the existing end face of the rail as the operation surface. If the end face is seriously corroded, it is necessary to use the angle Grinding can polish the surface brightly.
(2) Determining the butt gap: Considering the height of the rail itself, the gap cannot be too small, otherwise the welding rod cannot be penetrated into it for welding operations, so it is necessary to reserve enough gap.
(3) Weldment preheating: In the preheating process of orbital welding machine, a gas welding torch is used for preheating, and an infrared temperature measuring gun is used to ensure that the preheating reaches the specified temperature.
(4) Butt surfacing process: The whole welding process adopts the welding method of multi-layer multi-pass welding. Although this method is relatively inefficient, it can ensure the welding strength and the temperature between layers.
(5) Post-weld heat treatment: Orbital welding machine heating method uses gas welding torch. After heating to the specified temperature, asbestos felt is used for heat preservation to prevent cracks from appearing after welding.
(6) Grinding of workpiece after welding: Orbital welding machine keeps the weld and rail base metal smooth.
The biggest feature of orbital welding machine is local small-scale heating, high heating efficiency, easy to use, very suitable for rapid heating and cooling of high manganese steel welding, and also suitable for welding repair of local defects of rails. It is currently the most widely used in rail and rut welding repair methods. But it must be noted that the orbital welding machine must be properly preheated for rail welding. Because of the local heating and rapid cooling of the rail, it is easy to produce abnormal brittle structures such as martensite and bainite, which increases the brittleness of the rail. Preheating prevents abnormal tissue formation.
Using pipe fixed, welding carriage walking to reach all position automatic pipe welding, welding process with high efficiency and low cost of CO2 gas shielded welding. Pipeline all position automatic welding machine consists of welding control system, welding carriage with torch, welding power source, wire feeding device and accessories.

What should I do when there is a problem with the control system of the hydraulic storage tank lifting equipment?
Before using hydraulic storage tank lifting equipment, what should be paid attention to avoid malfunction?
What is the reason why the temperature of hydraulic storage tank lifting equipment is too high and cannot be lifted?
Countermeasures adopted: the hydraulic control system of hydraulic storage tank lifting equipment should be replaced immediately for maintenance due to common failures; maintain the cleaning of the hydraulic transmission system, and clean the filtration system (including the emulsion tank) on time; the key components of the hydraulic control system of the hydraulic press (such as Hydraulic seals) are very damaged to maintain, spring yellow parts should be sampled and tested on time, valves should be tested for characteristics, welding leaks should be repaired after dismantling the internal hydraulic seals, and pressure tests should be performed as required.
1. The weight of the object must be estimated before lifting, and remember to overload it.
2. When using, the center of gravity of the object must be determined, the focus point of the jack should be selected, and the placement should be stable. At the same time, the degree of softness and hardness of the ground must also be considered. If necessary, a tough wooden board should be padded to prevent skewing or even tipping during lifting.
3. This hydraulic storage tank lifting equipment is only used for jacking up. After the heavy object is jacked up, it should be supported by tough support (vehicle support, tough wood or other materials) to prevent the failure of the jack. Danger.
4. If several thousand hydraulic storage tank lifting equipment are used together, the lifting speed should be kept synchronized, and the load of each hydraulic storage tank lifting equipment should also be balanced, otherwise there will be a danger of tipping.
5. hydraulic storage tank lifting equipment should avoid sudden vibration when using it.
What is the reason why the temperature of hydraulic storage tank lifting equipment is too high and cannot be lifted?
There are several reasons for the high temperature of hydraulic storage tank lifting equipment: 1. Not enough hydraulic oil; 2. Too dirty hydraulic oil; blocked filter element; 3. Low pressure of safety valve; 4. Damaged working pump; In order from easy to difficult to rule out.
