Development of a Two-Dimensional Bead Shape Prediction Algorithm for Fillet FCAW Considering Welding Speed and Torch Offset

Automated welding processes have become increasingly critical in the shipbuilding, automotive, and aerospace industries. Precise weld seam tracking is essential for reliable automated welding, as torch misalignment causes weld defects and significant variations in bead geometry....

Influence of base metal geometry on heat dissipation, molten pool dynamics, and solidification behavior in GMAW bead formation

The geometrical configuration of the base metal can alter heat dissipation and molten pool behavior during gas metal arc welding (GMAW), even when the same nominal welding parameters are applied. This study investigated the effect of base metal width on heat dissipation, bead mor...
