'se-a50fs' Arc Welding Wire For Thin Steel Sheet

摘要

A new solid wire for Ar-CO_2 mixed gas welding has been developed for welding automobile part, such as frame assemblies and underbody parts, which are typically made of thin steel sheets 2-4mm thick. This new, innovative chemical composition wire design resulted in considerably improved molten pool properties. The most important advantages of this newly developed wire, compared to conventional solid welding wires, are as follows. 1) It has a wider and more stable bead shape; 2) It allows for higher welding speeds since undercut defects do not occur; 3) The welding condition settings are made easier for operators because the bead shape is immune to voltage changes; 4) The wire has very low slag generation and excellent paintability characteristics.
