Abstract
Transfer of yttrium into deposited high-strength low-alloy metal in welding with flux-cored wire in a shielding gas atmosphere and with covered electrodes of the basic type was investigated. Thermal desorption analysis revealed interaction of yttrium with dissolved hydrogen to form residual hydrogen depending on the concentration of yttrium. The effect of yttrium on microstructure of deposited low-alloy steel and mechanical properties of metal is shown.
