Segmented Elbow Welding Machines for Duct, Dust Extraction and Pipe Elbows
Sheet metal elbows 200 to 800 mm with 3 to 9 joints, and heavy wear-resistant elbows 108 to 426 mm
Overview
What it does
A segmented elbow, also called a lobster-back or gored elbow, is a set of short cut sections tacked together at an angle. These machines weld all the joints after the sections are butted and tacked, turning the elbow on a large hand-wheel style fixture so the torch stays on the seam.
The sheet metal model welds ventilation and oil pipe elbows from 200 to 800 mm in diameter, 1 to 5 mm thick, with 3 to 9 joints and any angle from 10 to 90 degrees, by MIG/MAG, TIG or laser. Size changes are made by entering parameters, without teaching.
The heavy model is a robot cell for wear-resistant elbows in power plant and mine dust extraction: carbon steel 5 to 10 mm thick, 108 to 426 mm in diameter, 3 to 13 sections and up to 150 kg.

Frequently asked questions
About this machine
How are the elbows prepared?
The cut sections are butted together and tack welded first; the machine then welds all the joints. Clamping is quick and does not need fine positioning.
Does it need programming for each size?
On the sheet metal model size changes are made by entering parameters, without teaching.
Do you have machines that form round duct elbows?
Yes. Our duct range includes the SBWT-1500 gorelocker, which forms locked elbows, and an elbow welder for small round elbows.
What lead time and warranty apply?
Lead time and warranty for this machine are confirmed in the quotation for your configuration.
Is the machine CE marked?
CE marking is confirmed at quotation. Tell us the destination country and we check what documents come with the machine.
