How To Detect Welding Defects. There are many ways to identify weld defects. Welding defects always appear as a result of specific physical and chemical characteristics of an Mg alloy mainly including oxidation and evaporation overheated coarse grains heat cracks pores and thermal stress and so on713.
A welding camera that provides a clear and consistent image of the weld means an operator can reliably detect defects in real time. DIMENSIONAL Welding-defects can be assessed by visual inspection and by measuring with simple weld gauges. Poor ductility of the given base metal.

The presence of residual stress can cause a crack on the weld metal. Poor ductility of the given base metal. The rigidity of the joint which makes it difficult to expand or contract the metals.
