Precision welding in high purity industries
Closed chamber welding heads are specially designed for autogenous welding of tubes without filler wire. Different sizes are available, covering a range of diameters from 1.6 mm to 170 mm (ANSI 1/16″ to 4″). Excellent results can be achieved when welding austenitic stainless steel, metals susceptible to oxidation, such as titanium, or alloys such as Inconel. Depending on the application, clamping cassettes or TCIs (Tube Clamping Inserts) are used to fix the closed chamber head onto the tubes and fittings, to be welded.
