Product information "ESAB OK Tigrod 12.64 TIG welding rod, G4Si1 / ER70S-6, Ø 1.6 x 1,000 mm, 5 kg, 126416R150"
The OK Tigrod 12.64, 1.6 mm, is a copper-clad solid rod for TIG welding of unalloyed and low-alloy steels. The rods are 1,000 mm long and come in 5 kg packs. In addition to this version (126416R150), we offer the rod in diameters of 2.0 mm, 2.4 mm and 3.2 mm.
Classification of the filler metal
According to EN ISO 636-A, the wire is classified as W 4Si1 and the weld metal as W 46 5 4Si1. According to SFA/AWS A5.18, the classification is ER70S-6; the wire type is specified as G4Si1 / ER70S-6. The alloy type is carbon-manganese steel; the wire composition is 0.074 % carbon, 1.68 % manganese and 0.95 % silicon. The shielding gas specified is I1 according to EN ISO 14175, i.e. argon.
Characteristic values of the weld metal
In its untreated state, the weld metal has a yield strength of 525 MPa, a tensile strength of 595 MPa and an elongation at break of 26 % according to EN. The notched impact energy is 150 J at -40 °C and still 90 J at -50 °C. According to AWS, the yield strength is 510 MPa, the tensile strength 610 MPa and the elongation at break 30 %. The chemical analysis of the weld metal is 0.08 % C, 1.28 % Mn, 0.80 % Si, 0.013 % S and 0.015 % P.
The classification and characteristic values are the same for all four diameters. The appropriate diameter depends on the weld preparation and the welding current.
Typical applications
- Root and joint welds on unalloyed and low-alloy steels
- General structural steels and fine-grained structural steels
- Pressure vessel steels, e.g. from P235/S235 to P460/S460, tested for suitability down to -40 °C
Approvals and conformity
Depending on the plant location, the following approvals and conformity markings are available: ABS 3Y (I1), BV 3YM, CE EN 13479, DB 42.039.48, DNV-GL III YM (I1), LR 3Y H15 (I1), UKCA EN 13479 and VdTÜV 05260. Which of these applies to a particular delivery depends on the plant location.
