2. Welding wire for steel structure: suitable for welding Bridges, pressure vessels, thickened plates and other steel structures, with high strength and toughness.

3. Stainless steel welding wire: suitable for welding stainless steel, alloy steel, heat-resistant alloy and other high-temperature alloy materials, with corrosion resistance and high temperature strength.

4. Aluminum alloy welding wire: suitable for welding aluminum alloy, magnesium alloy and aluminum magnesium alloy and other materials, with good electrical conductivity and heat conductivity.

Second, the characteristics and use of various welding wires

1. Ordinary carbon steel welding wire

Ordinary carbon steel welding wire is a kind of high quality welding material, suitable for welding low carbon steel, low alloy steel and carbon steel parts. It has excellent weldability and mechanical properties, high weld quality and good tensile strength and impact toughness. The diameter and gas protection of the welding wire should be selected when in use.

2. Welding wire for steel structure

Welding wire for steel structure is suitable for welding Bridges, pressure vessels, thickened plates and other steel structures. It has high strength and toughness, and can weld steel plates of various hardness. In use, attention should be paid to selecting the appropriate welding process and protective gas.

3. Stainless steel welding wire

Stainless steel welding wire is suitable for welding stainless steel, alloy steel, heat-resistant alloy and other high-temperature alloy materials. It has corrosion resistance and high temperature strength, high tensile strength and toughness after welding. In use, attention should be paid to the selection of appropriate gas protection and control of welding temperature.

4. Aluminum alloy welding wire

Aluminum alloy welding wire is suitable for welding aluminum alloy, magnesium alloy and aluminum magnesium alloy materials. It has good electrical conductivity and thermal conductivity, and can be welded to thin aluminum alloy parts. In use, attention should be paid to selecting the appropriate welding process and gas protection.
