Classification, advantages and disadvantages of stainless steel welding
The arc is produced between the tungsten welding wire and the workpiece, so the protection gas is pure argon and the welding wire is not charged, so it can be sent by hand or by machine. Then it is whether to use direct current or alternating current, depending on the welding material.
Metal gas shielded arc welding.It belongs to the gas protection welding, also is a kind of arc welding, that is, in the protection of gas, welding rod arc melting. Metal gas welding can be used in steel, non alloy steel, low-alloy steel and high alloy, etc. these materials are widely used. But one thing, its protective gas must be an active gas, such as carbon dioxide or a mixture of gases. The only drawback is that if the outdoor welding, then the workpiece can not be damp, otherwise it will affect the protection of gas protection effect.
The utility model has the advantages of universal use and easy operation, and is mainly regulated by people, and the welding seam material is an electric welding strip. Manual welding can weld almost all of the material, even outdoors, so it has good adaptability and is usually powered by direct current.Welding, either titanium type electrode, can also be sealed. The titanium electrode is easy to weld, the welding seam is beautiful, and the welding slag is easy to remove. But the drawback is that if you do not use it for a long time, you must bake it again to prevent moisture accumulation.
