What are weld lines in plastic injection molding? Weld lines, also known as knit lines, are formed in plastic injection molding when two or more melt flow fronts come together during the filling phase and fail to blend, resulting in a visible line. This usually occurs around holes or obstructions and areas of complex geometry, […]

Understanding Welding Defects Types of Weld Defects Welding, though a robust fabrication method, is susceptible to various defects that can compromise the integrity of the welded structure. These defects might arise due to numerous factors, including incorrect selection of welding parameters, faulty welding equipment, and inappropriate welding techniques. Broadly, these defects can be classified into
