DETAILS
THQ80-1 (ER110S-G) is an 800 MPa class high-strength low-alloy solid welding wire designed for M21 mixed gas shielding. Featuring excellent all-position usability, it yields weld metal with high low-temperature impact toughness.
Features
- Designed for welding 800 MPa grade high-strength low-alloy (HSLA) steels
- Optimized for M21 mixed shielding gas ($\text{Ar/CO}_2$)
- Delivers superior low-temperature impact toughness and high yield/tensile strength
- Exceptional all-position welding capability with a stable arc, deep penetration, and low spatter
Typical Applications
- Engineering machinery, heavy earthmoving, mining equipment, and crane booms
- Steel bridge construction, high-rise buildings, and heavy structural frameworks
- Vehicle manufacturing, heavy transport chassis, and mobile equipment
- High-strength pressure vessels and industrial steel fabrications
Welding Positions
- PA / PB / PC / PD / PE / PF / PG
