SAW Welding Tractors

IRCO submerged arc welding tractors are self-propelled mechanized welding systems designed to offer consistent and repeatable welds. It is available in several configurations based on weld process and industry application.

Rugged Frame & Body

For optimal weld consistency, the cast aluminum body and rigid post design maximize the CG orientation of the SAW equipment. The available knock down post configuration allows for quick set up and disassembly as well as entry through limited ID man ways for tanks and vessels.

Multiple Configurations & Options

For optimal control and improved torque when pulling long leads, the IRCO tractor is available in multiple drive configurations, including: 2WD, 4WD and Steerable options. The tractor is also available with various controls options, like: LED speed readout, weld engage and disengage, and forward-stop-reverse.

The IRCO tractor is used in many industries and applications, such as: shipbuilding, structural steel, tank & vessel and tanker car manufacturing, and transportation.
