Weld problem diagnosis
Defects, inconsistency, contamination, fit-up, distortion, process drift. Traced to the likely cause, not just the visible symptom.
Independent welding consulting in 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 independent technical read before money is committed. We identify the root cause and recommend the simplest sound path forward. Nothing in the answer is shaped by a sales quota.
Describe the material, the setup, and the symptom.
An experienced, independent read on the real cause, not the symptom.
Vendor-neutral and specific. Only what the job actually needs.
An experienced technical opinion before you change a process, replace equipment, reject a part, or build the wrong fix.
No equipment sales • No preferred vendor • No inflated scope
Defects, inconsistency, contamination, fit-up, distortion, process drift. Traced to the likely cause, not just the visible symptom.
Amperage, torch setup, shielding, consumables, equipment capability. Defined to what the work truly needs. Nothing padded.
Material, joint design, preparation, heat input, shielding strategy. Evaluated before the first arc or the next rework.
Fixturing, sequence, repeatability, throughput, operator access. Practical improvements, production-minded.
Prints, notes, and performance requirements turned into a clear, workable plan for the floor.
Direct instruction that puts the recommendation into practice on your floor.
We write Welding Procedure Specifications that hold up on the shop floor and in front of an inspector. Code-compliant WPS development, qualification support, and repair of procedures that are failing audits or producing rejects.

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.
