JQ.MG50-6 is a kind of carbon steel shielded welding wire. The melting speed of welding wire is fast when welding. It has stable arc, low spatters and beautiful appearance. Good corrosion-resistant on surface of base material. Decrease the probability of blowhole formation. All position welding has good performance CO2 or Ar+CO2 can be used as shielded gas.
1. Used for welding all kinds of 500MPa structural steel parts.
2. Used for welding all kinds of 500MPa plates and pipes.
2. Used for welding all kinds of 500MPa plates and pipes.
