Types of welding distortion and measures to reduce welding distortions

Types of welding distortion and measures to reduce welding distortions


Distortions or warping are occurring due to uneven shrinkage between the base metal of the weld and the base metal during heating and cooling after welding. Volumetric changes, especially when solder joints are constrained by clamped structures or by other materials around them, can easily lead to formation of stresses.
