Check out the in depth video where Guy breaks down how to remove slag the proper way in our #weldapp l. Weld flash and weld slag are important considerations in cable assembly design for applications in welding, spot welding, or stick welding environments such as industrial manufacturing floors and robotics and process automations. Slag is the hard, glassy layer that forms over welds in processes like stick and. Prevention of slag inclusions by grinding between runs The characteristic features and principal causes of slag imperfections are described. Radiograph of a butt weld showing two slag lines in the weld root Slag is normally seen as elongated lines either continuous or discontinuous along. The American Welding Society (AWS) defines slag as “a nonmetallic byproduct of the mutual dissolution of flux with nonmetallic impurities in welding and brazing processes. ” In short, it is the hardened layer left on the top of the weld made during flux-cored welding (FCAW). Slag, far from being just a byproduct, plays a pivotal role in ensuring the strength and integrity of welded joints.
