5 Welding Defects. 1 Too high welding amperage 2 Too fast electrode manipulation. Weldings defects are classified into the following types.
External Welding Defects. Incompletely filled groove or Incomplete penetration. Even if irregularities are very minimal but if the shape size and quality of the weld are way different than what is expected it is also called welding defects.
In the welding process both internal and external types of welding are quite common.
Weld failures can result from weld defects such as cracking or inclusions but there are a number of other issues in the welding operation that can also contribute to the problem. Even if irregularities are very minimal but if the shape size and quality of the weld are way different than what is expected it is also called welding defects. Incomplete penetration Slag inclusion Internal porosity Internal crack Incomplete fusion Internal Blowholes etc are examples of internal welding defects. 1 Slag Inclusion 2 Incomplete Fusion 3 Necklace cracking 4 Incompletely filled groove or incomplete penetration 20 External Welding Defects.
