Overview

What weld proving covers

Feasibility & Repeatability

Confirm the weld is achievable consistently (manual/robot), with repeatable torch access and positioning.

Parameter Window Finalization

Identify a stable window for current, voltage, speed, wire feed, and torch angle to handle variation.

Quality & Acceptance

Align output to your acceptance criteria - visual checks, NDT requirements, and production-ready proof.

Deliverables

What you will receive

Outputs

  • Trial report with selected weld parameters (window)
  • Weld sequence / torch angle recommendations
  • Defect observation notes + corrective actions
  • Sample weld results (as per agreed quantity)
  • Basic acceptance checklist (visual/NDT-ready)

Inputs needed

  • Material grade + thickness range
  • Joint type (lap/butt/fillet), gap tolerance
  • Component drawing / photo + accessibility
  • Acceptance criteria (visual, PT, MT, UT etc.)
  • Production target (takt time / weld length)
Process

How we execute (interactive steps)

Input Review

We review material, thickness, joint design, access, and quality criteria. We define trial plan, samples, and acceptance method.

Trial Runs

Execute test welds with controlled changes to parameters. We observe bead profile, penetration, spatter, and heat input.

Validation

Confirm repeatability across sample set. If needed, perform basic checks (visual, mock NDT prep) and refine settings.

Handover

Provide the parameter window, process notes, recommendations on fixturing, and a checklist for production acceptance.

FAQ

Common questions

No. Weld proving can be done for manual or robotic welding. The goal is to confirm feasibility and define a stable parameter window.
Yes. Share your acceptance standard and test method. We will align the trial plan to your inspection expectations.
We diagnose root causes (gas, wire, torch angle, travel speed, heat input, joint gap) and iterate until the window becomes stable.
Depending on complexity and sample availability, a basic proving can be completed quickly. For high-critical joints, we plan more iterations.
