FCH 3-21 / 3-38 / 6-76 / 9-114 welding heads

FCH 3-21 / 3-38 / 6-76 / 9-114 welding heads

Mechanised orbital welding

WELDING PROCESS: TIG

Closed welding heads for the mechanised TIG orbital welding of thin-walled pipe joints (external diameter 3 - 114 mm, wall thickness up to 3.5 mm) made of stainless steel, titanium, nickel-based alloys, aluminium and other materials without the use of filler wire.
