1 Continued on next page... Weld Defects-Their Causes and How to Correct Them With the correct welding conditions, techniques and material quality standards, the mig process will yield a very high quality weld deposit. However, as with any other welding process, weld defects can occur. Most defects encountered in welding are due to an improper welding procedure. Once the causes are determined, the operator can easily correct the problem. Defects usually encountered include incomplete penetration, incomplete fusion, undercutting, porosity, and longitudinal cracking. This section deals with the corrective action that should be taken.
