Application

AWS A5.18 E70C-3M Flux Cored Arc Welding Wire is a metallic flux cored wire designed to be used with Ar/CO2 for mild ssteel and 490N/mm2, high tensile steel, it's deposition rate is 10-30% higher than a solid wire. Multi-layer welding can be performed without removing slag. Smooth arc characteristics low diffusible hydrogen weld deposit low smoke and spatter levels. It is suitable for steeel structure, bridges, shipbuilding, vehicles, storage  tanks, etc.

Typical Mechanical Properties of Weld Metal

Welding Positions:

Notes:

1. Use DC(+) polarity.
2. When use larger diameters(1.6mm or higher), we recommend higher power supply of welder.
3. Trailer shield is essential to ensure that the weld pool is completely shield by75-80% Ar-25-20% Co2 gas until solidification is complete and no porosity problem.
4. Inter- pass temperature should be under 150℃ while in multiple-pass welding.

5. Keep the product dry, while it is stored or delivered.
