product description:
 

1)Straight seam welding (TIG Welding)
Straight seam welding (TIG Welding) is a very important part of the LNG cylinder production line.
The welding process introduced by the company can weld stainless steel, carbon steel and other materials,This machine is not only good in processing quality, but also more labor-saving for welders.

 

2)Straight seam welding (TIG Welding) requirements
2.1.Straight seam welding (TIG Welding) form: butt weld.
2.2.Straight seam welding (TIG Welding) process: PAW plasma (or PAW plasma + wire filler) welding process is used, and "99.999% argon" is selected as the plasma gas. Select "99.99% argon" as the shielding gas. For the cylinder plate thickness δ2.5~5.0mm, plasma single-sided welding and double-sided forming at one time. The movement of the welding gun is coordinated by a stable DC motor, linear guide rail, and mechanical transposition, and the welding process is automatically completed through electrical control.

3)Straight seam welding (TIG Welding) results
3.1 When the assembly and surface condition of the workpiece are good, the welding material and the shielding gas are in good condition, the workpiece after welding is subjected to 100% RT inspection, and the weld is qualified by RT inspection level II. Make the first pass rate of welding greater than or equal to 99%.
3.2 When the assembly and surface condition of the workpiece are good, the TIG welding material and the shielding gas are in good condition, the workpiece after welding is subjected to 100% RT inspection, and the weld is qualified by RT inspection level II. Make the first pass rate of TIG welding greater than or equal to 99%.
3.3 The weld reinforcement is within the range of 0-1.0mm.
3.4 The appearance of the weld is golden yellow or silver white.


4)Straight seam welding (TIG Welding) Equipment structure
The general drawing of the equipment is as follows:

LNG insulated gas cylinder double ring seam equipment is suitable for double ring seam welding of cylinder body and head, and adopts a horizontal machine tool structure as a whole. Mainly composed of bed guide rail, head and tailstock hydraulic tightening, high-precision hydraulic bracket, head and tailstock fixture, column and beam (2 sets), welding head (2 sets), hydraulic system, welding power supply system (2 sets) and electrical control system.
