Pipe / Flange Welding Machines

Flanged pipe spools can be economically fabricated if the welding task is performed in the horizontal position.  For straight pipe spools this is fairly straight forward, but with bent pipe spools, the process is more involved.  Jesse Engineering offers a line of machines to support this process, ranging from simple fixtures to automated welding machines.

The principal fixturing goal is to ensure the flange bolt holes are aligned for tack welding.  All of our Flange Welding systems accomplish this task.

The FW200MTF allows slip on flanges or elbows to be fit and welded to straight pipes from 1-1/2  to 8" nominal diameter.  The machine includes two pipe support roller sets and two flange holding chucks.  One of the chucks is reversible providing an elbow fitting platen, and the other chuck is rotatable for flange hole offset, i.e. "1 up" or "2 up".  After aligning flanges, the operator tack welds the assembly together.  After withdrawing the chucks, the operator may finish welding the assembly using the integrated turning rolls and steady rest provided.  Welding equipment is not provided.

FW500MTF

The FW500MTF allows slip on flanges to be fit and welded to straight pipes from 6" to 20" nominal diameter.  The machine includes two moveable pipe supports that center the pipes and two moveable flange holding chucks,  One chuck is rotatable for flange hole offset, i.e. "1 up" or "2 up".  After aligning flanges, the operator tack welds the assembly together.  After withdrawing the chucks, the operator may finish welding the assembly using the integrated turning rolls and steady rest provided.  Welding equipment is not provided.

FW360MTAW

The FW360MTAW is a complete semi-automatic pipe flange welding system.  Pipes of varied length from 1-1/4" to 14" nominal diameter roll into the machine.  Pre-loaded slip-on flanges are then manually tack welded onto the pipes.  Four automated weld heads are lowered down onto the tack welded pipe spools.  Four fillet welds are applied simultaneously.  Automated loading tables and unloading carts are normally available as options.
