MIG Welding Defects

November 20, 2018 @ 3:54:pm

Typical weld defects found in MIG welding are lack of fusion, burn through, crater/ crater cracks, undercut and porosity in the weld metal. These defects can be caused by a number of factors, such as wire feed, speed, travel speed, improper voltage, improper shielding gas, improper shielding gas flow rate, along with defects that occur from improper welding techniques, improper weld preparation and defective equipment.
