Weld irregularities occur for a variety of reasons and it results in different welding defects. They can be classified into two major categories: internal welding defects and external welding defects. External Welding Defects. External welding defects refer to discontinuities in the weld metal that are noticeable to the naked eye. Cracks Welding is one of the most efficient methods used in connecting different pieces of metal to make a single piece. It is a significant technique in sheet metal fabrication to complete a part’s manufacture. However, there is a possibility that welds can fail, causing welding defects. Weld defects are common in.

When the sheet metal is bent, the inner layer is subjected to compressive stress and the outer layer is subjected to tensile stress. Although these two stresses exceed the yield stress during elastic-plastic bending, in fact, there will always be an elastic deformation zone where the stress is lower than the yield stress when transitioning from tensile stress to . For thin sheet metal welding it can be 30 ampere while for thicker (e.g. 1/8” square groove weld)- it can go up to 220 ampere for example.
