Narrow Gap Welding - Tandem SAW


Narrow Groove thick section SAW welding is desirable for certain Vessel, Boiler, manufacturing processes.  AMET has designed an automated Narrow Groove Tandem SAW Weld Head.  Designed for a maximum welding capacity on a groove depth of 350mm.  Integral to the process, is a precision tilting drive unit for both lead and trail wire that allows for the programmable, or joystick positioning, of each wire to either sidewall.
