The Effect of Arc Current on Microstructure and Mechanical Properties of Hybrid LasTIG Welds of High-Strength Low-Alloy Steels

Popis výsledku v původním jazyce

A hybrid laser-tungsten inert gas (LasTIG) welding system was applied for 3-mm-thick S460MC and S700MC high-strength low-alloy steel sheet butt welding with the aim to reduce the cooling rate compared with laser welding. The effect of the electric current was evaluated. Increasing arc current led to the increase of fused metal and heat-affected-zone (HAZ) dimensions. Fused metal grains were larger whereas the microhardness increase toward the base metal was lower at higher currents in this region. Microhardness peaks corresponding to the coarse-grained HAZ were reduced at higher currents for S460MC but were almost not affected in S700MC. The tensile strength of both the laser weld and LasTIG welds was comparable to the base metal for both alloys.
