Submerged Arc Welding is valued for its efficiency and deep penetration. As well as it’s consistent results on heavy plate and structural applications. But like any welding process, it comes with its challenges. Problems such as porosity, lack of fusion, or arc instability can slow down production and increase costs. Plus, compromise weld quality if not addressed correctly.<\/p>\n
