Use

Welding is used for pressure vessels and other components rated at 830 MPa, such as WEL-TEN80, WEL-TEN80C, and for repair welding of defects in train couplers fabricated from E-grade steel.

Welding for pressure vessels and other components rated at 830 MPa.

High-strength, ultra-low-hydrogen, high-toughness welding electrode; exhibits high deposit strength, excellent ductility and toughness, and superior crack resistance. It also boasts outstanding process performance and is suitable for all-position welding.

High-strength, ultra-low-hydrogen, high-toughness welding electrode with high deposit strength, excellent ductility and toughness, and superior crack resistance. It exhibits outstanding process performance, is suitable for all-position welding, and is used for welding critical structures with a yield strength exceeding 790 MPa that demand high toughness; it can also be used to weld medium-carbon alloy steel components such as 34CrNi3Mo.
