Abstract

A technique for in-situ measurement of the surface tension of molten steel droplets in a gas-metal-arc welding plasma is described. Surface tension measurements obtained using this method are reported for ER 70S-6 wire, with varying shielding gas compositions, and compared with previously reported results. The in-situ technique is found to produce results consisten with values found in the literature, while incorporating the effects of alloy composition and arc atmosphere.
