Key words of this product: High tensile strength, weatherability grade steel welding wire High tensile strength, weatherability grade steel welding wire
Performance
This product adapts advanced copper electroplating technology. The surface of welding wire is smooth and level and the copper layer is uniform and firm. Being adapted cisarrangement technique, it has excellent weld technology property. Particularly it is suitable construct weld used at negative temperature. The welding line has good impacting rough. It has many advantages such as high productive efficiency, low cost, atmosphere corrosion and good function, etc.
Applications
Apply to the engineering machinery, minning machinery, heavy-duty, automobile mainly, the bridge, pressure container, railway locomotive, such trades as the autombile, etc.
