Welding Wire ER70S-G

The ER70S-G welding wire is a 500MPa grade carbon steel welding wire. The inclusion of titanium (Ti) element in the wire refines the molten droplets and weld metal grains, resulting in excellent high-current welding performance, superior impact toughness, and minimal spatter and smoke generation.

Notes:

1. Impurities such as rust, oil, and moisture must be removed from the weldment before welding.

2. The energy of the welding line will directly affect the mechanical properties of the weld. The magnitude of the line energy depends on the level of importance of the structure. The more important the structure, the smaller the line energy should be used.

3. The welding parameters provided are for reference only. The user should formulate the welding specification for suitable production according to the specific situation.
