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.

Designed for thick section, narrow gap SAW welding.
