6 Welding Errors During Custom Sheet Metal Fabrication
6 Welding Errors During Custom Sheet Metal Fabrication
September 13, 2022

Welding is an integral part of the custom sheet metal fabrication process. There are many varieties of welding gases and tools available for the welding technician to choose from. However, despite the advanced techniques, equipment, and methods available, it is a process with a lot of scope for errors. In this blog, we highlight some of the common welding errors during custom sheet metal fabrication.

 

Common welding errors during custom sheet metal fabrication

 

Not enough penetration:
Welders must ensure that the weld puddle penetrates the entire thickness of the metal being welded. If the weld puddle doesn't penetrate completely, the weld will be weak and may fail.

 

Not enough welding heat:
If the welding heat is too low, the weld will be weak and may fail. The welder must make sure that the metal is properly heated before welding so that the weld will be strong.

 

Excessive welding heat:
If the welding heat is too high, the weld will be too brittle and may break or crack. The welder must make sure that the metal is not overheated during welding.

 

Improper welding technique:
Welders must use proper welding techniques to ensure a strong weld. Improper techniques can lead to weak welds that may fail. This is one of the most common welding errors faced by beginners.

 

Poor fit-up:
If the parts being welded do not fit together properly, the weld will be weak and may fail. Welders must make sure that all parts are properly aligned before welding.

 

Lack of fusion:
Lack of fusion is another amateur mistake that happens during the welding process. Lack of fusion results in weak joints. This usually happens if the joints are not placed under the heat for enough time or if the heat is not as per the requirement.
