1. EQUIVALENT STANDARD AND CONFORMITY
- Vietnamese Standard TCVN: 3223-2000
- Vietnamese technical regulation QCVN: 21:2015/BGTVT, PART 6-SW53
- America Standard: AWS A5.18 ER 70S-6
- Japan Standard: JIS YGW12
- NK Registry: NK: KASW53TM
2. DESCRIPTION
- The advantage of the ER70S-6 welding wire according to the MIG/MAG welding method is that the welding productivity is 2.5 times higher than that of electric arc welding with protective coating, more diverse and flexible than automatic welding under the flux layer in welding position in space. During the welding process less toxic gas is generated.
- ER70S-6 is a welding wire with low carbon content, high manganese and silicon content, and extremely small sulfur and phosphorus impurities, creating welds with high strength and toughness.
- ER70S-6 is built with high precision, uniform wire direction, and is plated with a layer of high purity copper for preservation and a stable welding process.
- Welding wire ER70S-6 drum is mainly used in companies that manufacture car components, motorcycles, precision mechanics, etc., where welding is done by pre-programmed robot arms.
