» Thermal transfer equipment / Boiler
Resistance to high pressure with highest temperatures

Used for the production of different components in e.g. steam generator or waste heat boiler fabrication for coiled pipes, high pressure preheating units, endless tube fabrication, etc. Increase in productivity (up to 50 %) with a constant ISO documented quality, even under restricted accessibility.

Standard applications:

Tube O.D.	25 - 64 mm
Wall thickness	2,5 - 6 mm
Material	Heat resistant steels (Cr-Mo), carbon steels

» Nuclear applications Critical areas
Complete systems to decrease the intervention time in contaminated areas, video surveillance as well as computer aided welding with automatic joint tracking and on line parameter adjustment.

» Power generation / Petrochemical industry Heavy wall tubes and pipes by using ”TIG/GTAW cold wire process”
Competition is always increasing, schedules are always shorter, therefore companies must choose the most effective welding procedures taking into account: - required quality and productivity - environmental conditions - qualifications of personnel - competitivity

» Pipeline laying Large productivity gains and increased flexibility
Reduced arc time, reduced weld metal volume, increased productivity, better mechanical properties, reproducible and traceable quality.

» Cladding Controlled heat input / dilution
TIG/GTAW cold/hot wire process and numerical weld control system ensure permanent control of the heat input. Each individual parameter (welding speed, welding current, wire) is controlled independently but repeatedly.
