On heavy steel structures, iron anchor welding consumables are widely used in large-span space steel pipe structures, UHV transmission lines, wind power towers, heavy steel pipes for bridges, super high-rise buildings, offshore heavy industry equipment manufacturing and many other fields.

The series of gas shielded solid welding wires cover various grades from 50Kg to 90Kg. Among them, WH80-G and WH90-G are designed with Cr-Ni-Mo alloy system, low S, P, and low impurity elements to meet the requirements of high strength and high impact toughness at -40℃. Environmental protection non-plated solid welding wire WH50-6N, WH60-GN, etc., no acidification in the production process of the welding wire, no "copper fume" generated during the welding process, which effectively protects the operator's occupational health.

The series of submerged arc welding consumables cover the grade of 50-70Kg, of which MCJ10Mn2/TM.SJ101 and MCJ08Mn2E/SJ101Q have been purified and are suitable for the welding of large and thick wind power plates with a thickness of more than 1000mm. MCJ70Q is suitable for Q590 high-strength steel welding. Up to 120J or more.

Series of high-efficiency metal powder-cored flux-cored welding wires TMC-50M, TMC55N2M, TMC-69N3M2M, TMC-76N3M2M, TMC-76N4C1M, etc., are especially suitable for high-speed fillet welding. There is almost no spatter, the welding operation is excellent, and the welding efficiency is increased by more than 30% compared with ordinary solid welding wires. Among them, TMC-69N3M2M, TMC-76N3M2M, TMC-76N4C1M high-strength metal powder flux-cored welding wires have excellent mechanical properties at -50 °C, fully satisfying 70Kg and welding requirements of 80Kg high-strength steel.

A series of welding consumables for marine engineering YCJ91K2, YCJ551K2-1, WH55Ni1, MCJNi1K can meet the welding of large and thick plates for offshore engineering, and still have good mechanical properties at -60 °C.

Gas shielded gas welding flux-cored wire YCJEG50 can be used for one-time forming of thick plate vertical welding, with high welding efficiency, easy slag removal, and beautiful welding seam.
