Union ER 80S-B2 is a solid MIG/MAG wire for welding creep-resistant CrMo steels. It works in power generation, on superheaters, headers and pressure piping in chromium molybdenum steel.
The wire suits hand work with a semiautomatic torch and mechanised stations, fed continuously under shielding gas, in boiler, pressure vessel and petrochemical plant construction.
- Classification EN ISO: 21952-A, G 1CM
- AWS classification: A5.28 / SFA-5.28, ER80S-B2
- Diameters: 0.9 / 1.14 / 1.2 mm
Do not break off welding and do not let the joint cool below the interpass temperature before the fill is finished. Set the gas flow so the pool is covered over the whole length of the bead, and shield the station when you work in wind. Check the contact tip, a worn bore upsets the wire feed and causes burnback. Match the diameter to the thickness and the position, thinner wires are easier to control in constrained positions.
