Undercuts in Laser Arc Hybrid Welding
Physics Procedia, 2014 AbstractUndercuts are usually an imperfection in welding that either continuously or sporadically form, especially when welding at high speed. Efforts, usually lowering the welding speed or overfilling, are applied to avoid undercuts as they can significantly lower the fatigue properties of the welded workpiece. Undercut formation is complex and occurs

Hybrid laser‑arc welding of laser‑ and plasma‑cut 20‑mm‑thick structural steels [PDF]
, 2022 It is already known that the laser beam welding (LBW) or hybrid laser-arc welding (HLAW) processes are sensitive to manufacturing tolerances such as gaps and misalignment of the edges, especially at welding of thick-walled steels due to its narrow beam ...
