If you can't find such equipment, find a blacksmith's shop for brazing.

Argon arc welding? Is it too thin? If it is bad, it will leak.

The speed of argon arc welding is about 1m/5min. The speed of roll welding is much higher than that, and spot welding is faster.

Similar to spot welding, it is a kind of resistance welding. It has two electrodes with rollers, which rotate at a uniform speed to drive the workpiece to move at a uniform speed, and at the same time, it is electrified, heated and pressurized for welding.
