IW-G4Si1 SG3 The IW-G4Si1 (SG3) is a copper-coated solid welding wire with increased silicon and manganese content. Compared to SG2, it features improved mechanical properties, making it specifically recommended for higher-alloyed structural steels and applications where the weld joint is subjected to higher stress. Suitable for tensile strengths up to 640 N/mm2 in CO2 or Ar/CO2 shielding gas environments.Certifications: CE, TÜVTechnical Data: Classification EN ISO 14341-A: G 4Si1 AWS Standard AWS A5.18: ER70S-6 Tensile Strength 530 - 680 MPa Yield Strength > 460 MPa Elongation > 22%Welding current: DC (+) Key features and benefits: Stable Arc: Ensures smooth metal transfer with minimal spatter. Excellent Weld Quality: Results in cleaner, visually appealing, and X-ray quality welds. Universal Application: Highly manageable in both manual and robotic welding processes. Copper Coating: Ensures optimal current transfer and protects the wire from corrosion during storage. Attention! GLS delivery is not possible! Orders for wire coils can be placed per coil (depending on the type of the wire it applies to 1kg/2kgs/7kgs or 15kgs). Regardless of quantity the 15kgs coils are delivered exclusively on pallet. If it is a standard EUR size, the pallet will be charged at a net price of 12 EUR/pc regardless of the value of the whole order. Delivery charges may apply and vary depending on the destination.
