ER70S-4 MIG Welding Wire 0.03/0.035/0.045/(1/16) In 2/11/33/44 Lb
Conform to Standard :GB/T 8110 ER50-4,
ISO 14341-B-GS4, AWS A5.18 ER70S-4, JIS YGW12
Specification:
1. ER70S-4 is a Copper coated carbon steel rod for use in the TIG welding process. Typical tensile strength 490MPa. Ideal for root pass welding of pipes. Suitable for tanks, boilers, steel structural works, earthworks & construction works.
2 .It has CO2 or Ar+CO2 5%-20% as shielding gas. It has excellent welding performance. It has good one-time shaping performance. When used in argon-rich mixed gases arc welding, the bead is delicate and beautiful.
Purpose:
1.Used for welding thin plates.
2.Used for welding steel pipes.
