초록

In automotive company, a lot of researchers have investigated for the spatterless welding process during
last two decades. A spatter influences on the product quality such as strength and surface states. In this
paper, a hollow tip is proposed for spatterless process. An optimal size of electrode hole is obtained from
a weldability evaluation of each hole diameter. Through the cross section analysis, a phenomenon that
molten metal moves in the hole which located between two workpiece is observed, and this makes
spatterless welding process even though current is higher. Finally, widely acceptable weld area in lobe
curve is obtained by using hollow tip as compare with conventional no hollow tip. In this paper,
spatterless resistance spot welding with improvement weldability and productivity is proposed by using
hollow tip.
