How can arc strike appear on a guided bendtest? - Answers

Arc strikes can appear on a guided bend test when the welding process generates an electric arc that unintentionally contacts the base material or filler metal. This can occur due to improper technique, equipment malfunction, or inadequate shielding, leading to localized overheating and potential damage to the material. The resultant arc strike can weaken the weld and create defects that may compromise the integrity of the final product. Proper welding practices and equipment maintenance are essential to minimize the risk of arc strikes during testing.
