Abstract
The invention provides an ignition flux for arc stud welding, including 30-55 wt % SiO, 30-55 wt % NiO, 10-35 wt % AlF, and 5-25 wt % NiF, or including 30-55 wt % TiO, 30-55 wt % NiO, 10-35 wt % AlF, and 5-25 wt % NiF. 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.
