Inclusions welding
WebJul 19, 2024 · Slag Inclusions: Many weld processes use flux shielding, including shielded metal arc welding (SMAW), submerged arc welding (SAW), and flux-cored arc welding (FCAW). Welds produced by these methods are particularly susceptible to discontinuities known as slag inclusions. WebMar 26, 2016 · As you're welding, you're likely to encounter slag inclusions (foreign materials trapped in the weld metal at continuous or randomly spaced intervals). The most common is slag, a non-metallic solid material trapped in the weld or between the weld and the base metal. One of the most common causes of slag inclusions is the presence of coatings on ...
