IGNITION FLUX FOR ARC STUD WELDING AND ARC STUD WELDING METHOD

摘要

The invention provides an ignition flux for arc stud welding, including at least 30 wt % of an active agent, with the active agent selected from a group consisting of SiO₂ and TiO₂. As such, the electric arc can be easily created and smoothly formed. The invention further provides an arc stud welding method utilizing such ignition flux. As such, the fastener and the metal workpiece can be tightly connected together without the need of inserting an ignition tip into the welding portion of a fastener.
