The welding methods of stainless steel pipes include manual welding, MMA, metal polar gas shielded arc welding and tungsten inert gas arc welding, metal polar gas shielded arc welding (MIG/MAG) and tungsten inert gas arc welding (TIG).

手工焊

Manual welding

使用非常普遍，且操作容易，主要是靠人进行调节，焊缝填充材料为电焊条。手工焊几乎能焊接所有的材料，即使在室外也可以，因此它具有很好的适应性，一般焊接时是采用直流电。

It is very common and easy to operate. It is mainly regulated by people, and the filler metal is an electric welding rod. Manual welding can almost weld all the materials, even in the outdoor, so it has good adaptability, and the general welding is the use of DC.

电焊条，既可以是钛型焊条，也可以是缄性的。钛型焊条比较容易焊接，焊缝美观，且焊渣容易去除。但缺点是如果长时间不用后再使用，那么必须重新进行烘烤，以防潮气积聚。

Welding, either titanium type electrode, can also be sealed. Titanium electrode is easy to weld, the weld is beautiful, and the slag is easily removed. But the drawback is that if you don't use it for a long time, you must re - roast it in order to prevent the accumulation of moisture.
