QuSG2 Bobbin – Laser Welding Wire Mild Steel SG2 / ER70S-6 (1.5125) – S235 to S355, Boiler Making

QuSG2 Bobbin – Laser Welding Wire Mild Steel SG2 / ER70S-6 (1.5125) – S235 to S355, Boiler Making

QuSG2 is the standard wire for unalloyed and low-alloy steels: EN ISO 14341-A G 42 4 C/M 3Si1 · AWS ER70S-6 · DIN 8559 SG2 · filler no. 1.5125.

SG2 is the most widely used welding wire there is — here in laser quality. It covers the whole field of structural steels: S235JR to S355J2, the boiler steels P235GH / P265GH / P295GH and fine-grain steels up to S420N. Per the datasheet the weld metal is crack-safe even in multi-layer welding — which is why it also suits larger build-up volumes, not just the thin bead. Hardness 200–250 HB.

Recommended base materials

  • S235JRG2 – S355J2
  • P235GH, P265GH, P295GH — boiler steels
  • Fine-grain steels up to S420N, StE255 – StE380
  • St 35 – St 55, GS 38 – GS 52, HI/HII, 17Mn4, 19Mn

Typical applications

  • Vehicle construction
  • Vessel and boiler construction
  • Machine tool construction
  • Joints and build-ups on low-alloy steels

Properties and advantages

  • Crack-safe even in multi-layer welding (datasheet)
  • Covers S235 to S355 and fine grain up to S420N
  • Re 430 MPa · Rm 500 MPa · A 22 %
  • 200–250 HB
