Most people search orbital welding procedures because something already went wrong: welds look good outside but fail X-ray, pipes warp, or production is too slow.

From our factory experience building automated pipe welding lines, a stable weld is not magic—it’s a workflow. A repeatable one. Below is how we actually run projects using an orbital tube welding machine and trained operators.


 

1. Workpiece Preparation – Where 70% of Problems Begin

Good orbital welding procedures start before the arc.

In our shop we insist on:

• Precision cutting – tube squareness within 0.1 mm

• Bevel prep – thin wall often needs zero-gap fusion

• Cleaning – acetone wipe + oxide removal

• Material check – stainless grade confirmation

If the pipe is dirty, no orbital tube welder can save it.

For pharmaceutical or semiconductor pipelines, preparation is even stricter because of high purity orbital welding requirements. Any oil or oxide becomes contamination.

That’s why our orbital welding system packages include alignment tools and prep guidelines—not just a machine.


 

2. Clamping and Alignment – Quietly Critical

Bad alignment kills beautiful welds.

Real orbital welding procedures always define:

• Clamp type

• Concentricity tolerance

• Gap control

• Tack-free positioning

Our closed-loop orbital tube welding machine fixtures hold pipes without tack welding, which avoids internal oxidation—important for high purity orbital welding projects.

Customers often discover their biggest improvement after switching from manual fit-up to automated clamping with an orbital tube welder.


 

3. Shield Gas Setup – Invisible but Decisive

People focus on amperage, but gas control is the real hero of orbital welding procedures.

We set:

• Shield gas flow

• Back purge timing

• Oxygen ppm target

• Pre-flow & post-flow

For food-grade or biotech lines, our high purity orbital welding setups require <20 ppm oxygen before arc start.

A professional orbital welding system must maintain gas stability during rotation. That’s why our welding heads use sealed chambers and balanced flow channels.

An orbital tube welding machine without purge stability is just a rotating torch.


 

4. Welding Program Setup – Not One Number, But a Curve

Customers always ask:
“What current for 2-inch stainless?”

Real orbital welding procedures don’t use one number. They use curves.

We program in the orbital tube welder:

• Start current

• Peak current

• Background current

• Downslope

• Rotation speed

Our orbital tube welding machine controllers store parameter libraries for different pipe sizes and alloys.

For thin stainless tubing in high purity orbital welding, we use lower heat input and multi-segment cooling to prevent discoloration and carbide precipitation.

A good orbital welding system remembers good welds so operators don’t reinvent them.
 

5. Post-Weld Inspection – Trust but Verify

Real factories don’t guess.

Standard orbital welding procedures include:

• Visual inspection

• Weld bead profile check

• Borescope internal check

• Pressure test or X-ray

With a calibrated orbital tube welder, weld consistency becomes predictable. Operators stop worrying, inspectors stop rejecting.

That’s the moment automation pays for itself.
 

From Workflow to Complete Orbital Welding Solutions

Because we manufacture automated pipe welding equipment ourselves, we don’t just sell an orbital tube welding machine.

We help customers build their own library of proven orbital welding procedures, optimized for their materials, pipe sizes, and production speed.

Our complete orbital welding system includes:

• Equipment and fixtures

• Process parameter database

• Operator training

• On-site commissioning

• Support for high purity orbital welding projects

Many clients come to us only wanting an orbital tube welder.
They leave with a stable production workflow.

Because in real manufacturing, machines matter—but procedures make profit.
