METHODS OF DETERMINING WELD QUALITY BY REALISING A WELD SIGNATURE ANALYSIS

摘要

A method of determining weld quality includes the step of providing a reference weld signature having a first shape. A weld signature (200) of a welding parameter is captured, wherein the weld signature (200) of the welding parameter has a second shape. The first shape is automatically compared to the second shape and a weld signature shape difference between the first shape and the second shape is determined. A weld fault condition is determined based on the weld signature shape difference.
