Weld Quality Control

An important topic given welding

• is complexly dependent on several physical Laws of the Universe
• is a "special process" (ISO9000 definition) because quality cannot be determined by examining a completed weld (quality can only be guaranteed by controlling the conditions under which the weld is made to those proven to give a satisfactory weld)

Ali MIG/GMAW welding with quality control
Proposed project to obtain consistent good quality at good productivity for the welding of marine-grade "5000-series" Al-Mg alloys using well specified MIG/GMAW welding.

Stainless steel MIG/GMAW quality - work lost overseas
A cautionary description of an event I had first-hand experience of, where work was lost overseas due to consistent poor weld quality.
There is a strong similarity between this and the "Ali-MIG quality control" challenge.
