Union X 85 T is a low-alloyed, high-strength solid wire. It suits welding quenched and tempered high-strength steels on working machines, booms, cranes and structures that need a high yield strength.
The wire is fed continuously from the feeder and welded under shielding gas, by hand and on mechanised stations, on mobile structures, machine frames, cranes and parts built for a lower own weight.
- Classification EN ISO: 16834-A G 69 6 M21 Mn3Ni2.5CrMo
- AWS classification: A5.28 / SFA-5.28 ER110S-G
- Shielding gas: M21, C1
- Approvals: DB (42.132.74), ABS, DNV, CE
Do not exceed the permitted interpass temperature, an overheated heat affected zone loses its toughness. Match the drive rolls to the wire diameter and check the liner, wire slip shows up at once in an unstable arc. Watch the wire stick-out from the contact tip, too long a one lowers the arc voltage and worsens the fusion.
