Arc Welding Service

CATEGORY

TYPE

Seamless metal core wire for heat and creep resistant applications.

APPLICATIONS

Construction of containers, boilers, machines and pipe work. Steam boilers and turbines construction.

PROPERTIES

Good arc restriking even with cold wire tip, suitable for robot applications. Ideal for use of short arc and spray arc. Excellent gap bridging for root welding. High-efficiency type for economic production of creep resistant steels and pressure-hydrogen-resistant 2¼Cr1Mo-steels. Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage in unconditioned condition.
