Pipe Welding
Certified pipe welders for process piping, pipelines, and plant systems — built to code, tested, and backed by a crew that’s worked the plant side of the job.
Built to Code. Built to Last.
Pipe welding is unforgiving — a weak joint doesn’t fail on the bench, it fails under pressure, on a system your plant depends on every day. Southern Welding’s certified welders handle process piping and pipeline welding across carbon, stainless, and specialty alloys, using TIG, orbital, and manual processes matched to the application, not just whatever’s fastest.
Every weld is performed to the applicable code and documented — because in cement, mining, power, and pulp & paper plants, “probably fine” isn’t a standard we work to.
- TIG and orbital pipe welding
- Process piping — carbon, stainless, specialty alloys
- Pipeline sections and tie-ins
- Code-certified welders with documentation
- Emergency and planned pipe repair
- Nationwide mobilization from our Texas, Louisiana, Alabama, Florida, and Arizona teams
What We Do
Three Ways We Weld Pipe
Pipeline Welding
Pipeline sections, tie-ins, and repairs welded to code by crews experienced in both shop and field conditions.
Get a Quote →Specialty Pipe Processes
TIG and orbital welding for the jobs that demand tighter tolerances than a standard weld — food-grade, high-purity, or thin-wall applications.

From Scope to Sign-Off
Scope & Material Review
We review drawings, specs, and the piping material before crews mobilize — so the right process and filler metal are confirmed before any arc strikes.
Fit-Up & Prep
Joints are prepped, fit, and inspected to spec. On pressure systems, this step is where most future failures get caught before they happen.
Weld & Inspect
Certified welders execute to the specified procedure. In-process and post-weld inspection — including NDT where required — verifies the joint before the system goes back into service.
Documentation & Handover
Weld logs, material certs, and inspection records are handed over complete — so your team has the paper trail when the auditor or the next outage comes around.
