Certified welders, your site, no equipment transport.

Mobile Pipe Welding

Mobile Pipe Welding

We bring pipe welding expertise directly to your site, so there is no need to transport large equipment or take a system out of the building. Our welders arrive with the right tooling, consumables, and safety gear for the job in front of them, and they are qualified for the specific system they are working on.

What We Do

  • SMAW (stick), GTAW (TIG), and GMAW (MIG) processes
  • Carbon steel, stainless steel, and alloy piping
  • Natural gas, steam, and chilled water systems
  • Boilers, pressure vessels, and high-pressure piping
  • Complex mechanical installations and retrofits
  • Burst pipe and repairs to failed lines

Why IMW

  • TSSA approved; TSSA certified and Red Seal welders
  • Documented procedures and welder qualification records
  • Flexible scheduling — nights, weekends, shutdown windows
  • On-site project guidance from people who have done this for decades
  • One contractor from cut to final weld

Common Questions

What does mobile pipe welding mean?

We bring certified welding capability to your site rather than requiring that a system, an assembly or a piece of equipment be transported to a shop. That matters most when the item is installed, large, or part of a live system.

Which welding processes do you use?

SMAW, GTAW and GMAW. Process selection depends on material, position, access and the applicable code.

Are your welders certified?

Yes — TSSA-certified welders for pressure piping, boilers and pressure vessels, and Red Seal welders across SMAW, GTAW and GMAW.

Can you weld on a system that is still in service?

Welding on live pressurized systems is carried out under our hot tapping and line stopping authorization, QA-03336, using qualified procedures. See hot tapping.

Do you do emergency call-outs?

Scheduled evening, weekend and holiday work is routine so plant production is not interrupted. We do not operate an unscheduled emergency call-out service. For burst pipes and failed lines, phone is faster than email.
