Applications
For joining creep-resistant and fine-grain steels, e.g.:
EN 10025-2: S 235 J2 – S 355 J2
EN 10025-3: S 275 N – S 420 N
EN 10025-4: S 275 M – S 420 M
and corresponding casting and pipe materials.

Typical examples of use are:
Components from boiler and container construction, in particular pipe welding in heat exchangers; furnaces in energy generation plants; in ventilation, machine, steel, car body, carriage and ship construction.

Processing instructions
Clean the welding areas. Adjust the heat control during welding to the component, its material and dimensions. Limit the interpass temperature to 250 °C. Weld with a short, spray or pulsed arc; use pulse-arc technology if possible.
