Stainless steel welding method:

1. Manual welding (MMA): Manual welding is a very common and easy-to-use welding method. The length of the arc is adjusted by hand, which depends on the size of the gap between the welding rod and the workpiece. At the same time, when used as an arc carrier, the welding rod is also a weld filler material.

2 .MIG/MAG welding: This is an automatic gas shielded arc welding method. In this method, the arc burns between the current carrier wire and the workpiece under the shield of protective gas. The wire fed by the machine acts as a welding rod and melts under its own arc. Due to the versatility and specificity of MIG/MAG welding, it is still the most widely used welding method in the world. It is used for steel, unalloyed steel, low alloy steel and high alloy based materials. This makes it an ideal welding method for production and repair. When welding steel, MAG can meet the requirements of thin gauge steel plates with a thickness of only 0.6 mm. The shielding gas used here is Active gases, such as carbon dioxide or mixed gases. The only limitation is that when welding outdoors, the workpiece must be protected from moisture to maintain the effect of the gas.

3. TIG welding: The arc is generated between the refractory tungsten welding wire and the workpiece. The shielding gas used here is pure argon, and the welding wire fed in is not charged. The welding wire can be fed either manually or mechanically. There are also some specific uses that do not require the feeding of welding wire. The material being welded determines whether direct current or alternating current is used. When direct current is used, the tungsten welding wire is set to the negative pole. Because it has a deep penetration ability, it is very suitable for different types of steel, but it has no "cleaning effect" on the weld pool.
