Purpose:
For welding important low carbon steel structure and low strength grade low alloy steel structure, such as Q235,09MnV, 09Mn2 and so on.
Features:
J422 is a carbon steel electrode with titanium coating. AC, DC dual-use, all-position welding. Excellent welding process and mechanical properties; arc stability, small spatter, easy slag, easy re-arc; beautiful weld shape, welding wave can be wide, narrow, thin, thick, easy welding, efficient.
Points to note:
In general, do not bake before welding. The electrode must be baked at 150-170℃ for 0.5-1 hour after being wet.
Welding position:
