Webb25 feb. 2024 · This type of weld defect occurs when there is an insufficient fusion between the base metal and the weld metal. This creates a gap under the joint or in between adjoining weld beads. Due to the insufficient fusion, molten metal can not reach all areas of the weld and thus creates the gap. This kind of weld defects weakens the structure. Webb3 jan. 2024 · The phenomenon of weld decay occurs in : Cast iron Brass Bronze Stainless steel
