Description

ER70S-6 copper welding wire

coated welding wire, suitable for 100% CO2 and argon and CO2 mixed gas protective weld. Copper coated welding wire ER70S-6, suitable for 100% CO2 and argon and CO2 mixed gas protective welding supplies.

1) Type and characteristic:
welding wire ER70S-6 is a kind of mild steel copper coated weld wire, suitable for 100% CO2 and argon and CO2 mixed gas protective weld with stable feasibility, good welding seams, less spatters and excellent welding supplies process properties. Suitable for all-position weld work.

2) Applications:
used to weld ship building steel (A , B, D, E, A36, D36, E36) and equivalent mild steel or 550Mpa grade mild alloy steel, such as container buildings, bridge building, machinery manufacturing, railway construction, pressure vessels for semi-auto or automatic gas shielded weld and general welding purposes etc.

3) Conform with:
GB/T 8110 ER50-6
ISO 636-A-W 42 3 W3SIL
AWS A5.18 ER70S-6
ISO 636-B-W 49A 3 W6
BS EN 1668-W 42 3 W3SIL
JIS Z3316 YGT50

A general purpose weld wire for fabrication of mild steel. Contains more deoxidizers than ER70S-3. The additional deoxidizers also provide better wetting, giving a flatter bead shape and the capability of faster travel speeds. Usually used with 75/25 (argon/CO2) shielding gas or with higher contents of argon, such as 90/10. Can also be used with 100% CO2. Conforms to AWS A5.18 ER70S-6.  Very good weld performance and the weld metal shows lower temperature impact toughness. It is mainly for butt and fillet welding structures made by shipping steels and low alloy steels, such as ships, containers, vehicles, engineering & construction machinery and so on.

It is an excellent choice for weld on metals with a medium to high presence of millscale. For best performance use on clean, oil-free and rust-free base material. Superior weld appearance, feedability and excellent arc characteristics.
