MIG welding has highlight advantages, such as high density of current, strong penetrability, smooth welding quality.
5mm SS sheet could be full-penetration welded without groove.
MAG welding has features as high welding speed, seep weld pool, high deposition efficiency, perfect welding quality,
low welding deformation, low cost and easy operation. One time welding with full penetration, single side welding
with double side forming.
TIG welding speed is nearly one-time lower than that of MIG. But welding quality is perfect more easily polished than
that of MIG welding.
