What industrial welding services cover
Industrial welding covers any code-driven welding work: structural (AWS D1.1), pressure vessel (ASME IX), pipeline (API 1104), aerospace (AWS D17.1, Nadcap), and food/sanitary. Common processes: SMAW (stick), GMAW (MIG), GTAW (TIG), FCAW (flux-cored), SAW (submerged arc), and increasingly orbital and robotic systems. Most Texas welding shops carry one or more of these certifications and operate under qualified welding procedure specifications (WPS) per their certification.
What to look for in a supplier
Match the certification to the work: AWS D1.1 for structural steel, ASME Section IX for pressure-vessel and boiler work, API 1104 for pipeline, AWS D1.6 for stainless structural, AWS D17.1 for aerospace. Confirm the shop's WPS covers your specific base material, filler, position, and thickness range — generic AWS certification doesn't guarantee any specific weld is in scope. Welder qualifications (welder performance qualifications, WPQ) must match the WPS. For aerospace and pressure-vessel work, ask about NDE capabilities: radiography (RT), ultrasonic (UT), liquid penetrant (PT), and magnetic particle (MT) — and whether they're in-house or subcontracted.
FAQ
Common questions
What's the difference between AWS D1.1 and ASME Section IX?
AWS D1.1 is the structural welding code — governs welded structural steel for buildings, bridges, equipment frames. ASME Section IX is the welding-procedure-qualification standard used by ASME pressure-vessel and piping codes. They cover different territory; many shops are certified to both.
What's a Welding Procedure Specification (WPS)?
A WPS is the documented recipe for a specific weld — base materials, filler metal, joint design, position, electrical parameters, pre-heat, post-weld treatment, and inspection. WPS is qualified by a procedure qualification record (PQR) showing a sample weld passed mechanical and NDE testing. Code work requires welding within a qualified WPS.
What's the difference between TIG and MIG welding?
TIG (GTAW) uses a non-consumable tungsten electrode and separate filler rod — slower, cleaner, more precise; standard for stainless, aluminum, and code work where weld quality matters. MIG (GMAW) uses a continuously-fed wire that's also the filler — much faster, used for high-deposition work and production. Most shops do both; choose TIG for code work, MIG for high-volume production fab.
What NDE methods are standard for code-driven welding?
Visual inspection (VT) is universal. For volumetric inspection, radiography (RT) and ultrasonic (UT) are the standards — RT for thinner sections and pressure-vessel butt welds, UT for thicker sections and complex geometries. Surface NDE uses liquid penetrant (PT) for non-ferrous or magnetic particle (MT) for ferrous. Code work specifies which methods apply per joint.
