Gas Shielded Solid Welding Wire
Gas Shielded Welding Wire
Gas shielded welding wire is made of excellent steel by drawing, straightening and copper coating and has various characteristic. It has been widely used in all kinds of field. Such as automotive industries, construction machinery production, shipbuilding, metallurgical equipment production, bridge, civil works, petrochemical industry, pressure vessels of boiler, locomotives, etc. Some of its advantages are as below:
1. Low welding cost
2. High productivity and low electricity consumption
3. Easy to operate, all position welding
4. Very low hydrogen content in the weld and lower nitrogen content, excellent crack-resistance
5. Little deformation after welding
6. Wide applicability. Suitable for welding thin, medium and thick plates.
