High Carbon steels MIG ER70S-G weld fabrication jointing
Application
Suitable FOR shipbuilding, bridge, construction and excavation welding applications, also used in high current finger plate butt welding, fillet welding and cross welding.
The standard we met: GB/T8110 G 49A4 C1/M21 S11 N , AWS A5.18 ER70S-G & A5.18M ER49S-G, ISO14341-A:G 42 4 C1/M21 Z4Si1, ISO 14341-B:G 49A 4 C1/M21 S11
JIS Z3312 YGW-11/15
Peculiarity
Environmental protection and health, and can avoid the adverse impact of copper on welding quality;
In addition to proper alloying elements such as Si and Mn, sufficient Ti elements are added to stabilize the arc and make the arc transition refined; The relative amount of splash and smoke is also significantly reduced;
Ti has the role of grain refinement of the weld pass, so that the toughness of the weld pass is greatly improved, and it can also play its superior performance in large flow welding.
