Pressure head type welding machine
Pressure Head Type Elbow Welding Machine
It is an exclusive equipment for heavy duty welding of pipe with large diameter in C.S, A.S, L.T.S, S.S, D.S.S, Nickel Alloy etc., based on many years' experience in pipe spool fabrication, also combined with on-site condition.
It is consisted of pressure head type elbow welding machine, pipe supporter, rail skid, welding control system, Miller welding system and electric control system etc., which can complete TIG root pass, SAW fill & cap pass welding of pipe + pipe, pipe + flange, pipe + elbow etc. butt seam.
It can effectively control the eccentric force during rotating process of eccentric fittings to guarantee the welding stability. It can realize suspending, positive/negative rotating and VF speed adjusting function during rotating. The welding torch adjustment mechanism can realize up/down, left/right and angle adjustment.
Adopt imported Miller welding power supply and relative exclusive assistant equipment to realize TIG, SAW welding, further to satisfy the welding requirement of pipe in several thickness on site.
