What type of MIG welding wire is suitable for Q355 material?

[RafaelRose]

Use ER50-6 welding wire for welding. ER50-6er: ER50-6er represents the welding wire, where 50 indicates the minimum tensile strength of the deposited metal at 500 MPa, and 6 denotes the chemical composition code 6. ER50-6er represents the welding wire, where 50 indicates the minimum tensile strength of the deposited metal at 500 MPa, and 6 denotes the chemical composition code 6. Welding requirements: For applications requiring good plasticity, high impact toughness, excellent low-temperature performance, and strong crack resistance, alkaline or high-toughness electrodes should be selected. For welding medium carbon steel or cast steel, ultra-low hydrogen type, high-toughness electrodes are generally recommended, supplemented by preheating and other process measures.
