- WELDOX960, as low-alloy high-strength steel in new generation, is widely used in construction machinery and other heavy-duty field. In the paper, mixed gas shielded arc welding is adopted for multi-pass welding on low alloy high strength steel WELDOX960. Different intensity match methods are adopted for respectively preparing six groups of samples. Microstructure of weld joint is tested and analyzed after welding. The result shows that micro-structure in filling welding of six groups of samples is basically similar to cosmetic welding, which is composed of acicular ferrite and carbides. Backing weld micro-structure of samples 50-80, 50-85 and 50-90 are essentially the same. Their microstructures are basically composed of a small amount of pearlite, proeutectoid ferrite and acicular ferrite.
