Weld problem diagnosis
Trace defects, inconsistency, contamination, fit-up, distortion, or process drift back to the likely cause—not just the visible symptom.
Independent welding consulting — St. Louis, MO
Independent welding consultation that finds the real problem, defines what the job actually requires, and keeps you from buying more process, equipment, or complexity than you need.
Diagnose first. Specify second. Spend only where it matters.
ArcLight gives owners, shops, and technical teams an experienced, independent read on the job before money gets committed. We separate the must-haves from the nice-to-haves, identify the root cause, and recommend the simplest sound path forward—without a sales quota shaping the answer.

Trace defects, inconsistency, contamination, fit-up, distortion, or process drift back to the likely cause—not just the visible symptom.
Define the amperage, torch setup, shielding, consumables, and equipment capability the work truly needs—nothing padded.
Evaluate material, joint design, preparation, heat input, and shielding strategy before the first arc or the next rework.
Find practical improvements in fixturing, sequence, repeatability, throughput, and operator access.
Turn prints, notes, and performance requirements into a clear, workable plan for the floor.
Help welders and teams put the recommendation into practice with direct, production-minded instruction.
Aerospace TIG experience informs practical recommendations for titanium and stainless, with grounded process support across carbon steel and aluminum.
Cleanliness, shielding, heat control, and deliberate gas coverage—including Pyrex or ceramic cup selection to suit the joint and access.
Process, purge, heat-input, and distortion guidance for clean, repeatable TIG work.
Practical process and joint recommendations for fabrication, tooling, and repair applications.
Fit-up, cleaning, machine setup, and technique guidance for lightweight component work.
Equipment vendors solve for what they sell. ArcLight solves for your actual requirement. The recommendation may be a different setup, a fixture change, better preparation, focused training—or confirmation that what you already own is enough.
It depends on the problem. Tell us what's going on and we'll give you a straight answer on scope and cost before any work starts — no surprise invoices.
No — and that's the point. With nothing to sell, the recommendation is shaped by your job, not a sales quota.
Yes. On-site across the St. Louis metro, remote anywhere else. Most engagements start with your photos, procedures, and a conversation.
