Inclusions welding
WebOct 13, 2024 · The most common causes for weld slag inclusions are improperly handled flux, poor flux quality, and poor welding technique. Although slag inclusions are most commonly associated with submerged arc welding, flux-cored arc welding and stick welding, they can also transpire in MIG welding. Weld slag inclusions can lead to … WebWelding slag inclusions can affect the quality of welds produced with flux-cored processes and occur when the slag becomes trapped in the weld when it solidifies. There are several best practices and techniques to help minimize this risk.
