this paper investigated the hydrogen effects on facture toughness in the fusion area of stainless steel weld overlay.
研究了氢对不锈钢堆焊层熔合区的断裂韧性的影响作用。
it indicated that double wire welding technique not only advanced the efficiency of welding and quality of weld seam but also improve the tensile strength and facture toughness of the welded joints.
