Welding Sourcing Across Asia
Certified welded fabrications and assemblies, sourced from vetted manufacturers across India, China, Vietnam and Thailand, with welder qualification review, in-process inspection, and logistics handled for you.
Your trusted partner for custom welding sourcing
A welded assembly is only as strong as the weld itself, which means the factory's welder qualifications, procedure documentation, and inspection discipline matter as much as the equipment on the floor. AASA works with U.S. businesses to identify overseas welding partners that can actually back up their work with WPS and PQR documentation, not just a finished part that looks acceptable. Our network across India, China, Vietnam, and Thailand covers MIG, TIG, and robotic welding, matched to your material, joint type, applicable code, and volume.
AASA stays involved past the introduction. We review your drawing and weld symbols, confirm the factory's welder certifications against your requirements, and monitor production with in-process visual checks and, where specified, non-destructive testing. Every order is inspected against your drawing before it ships, and freight and customs are coordinated through the same team, so a welded frame, skid, or pressure component reaches your dock as a finished, verified part.

Comprehensive welding capabilities
Welded fabrication spans a wide range of processes, and the right one depends on your material, joint access, and how many pieces you need. AASA sources across the processes below, and factory selection is based on the certifications and equipment your specific drawing calls for.
High-deposition welding for carbon steel structural fabrication, brackets, and higher volume production runs.
Precision welding for stainless steel, aluminum, and thin-wall or appearance-critical parts.
Fixtured, repeatable robotic welding cells for high-volume assemblies with consistent weld quality.
Fast, repeatable joining for sheet metal enclosures, brackets, and light-gauge assemblies.
Laser or plasma cutting, forming, and jig-based fit-up before and after welding.
Grinding, blasting, passivation, and painting to bring welded parts to final appearance and spec.
Send your drawing or spec and we'll come back with a factory match and a quote in 48 hours — no obligation.
Join the manufacturers already sourcing welded fabrications through AASA.
Weldability, filler metal selection, and post-weld treatment all depend on the base material, and getting that wrong is one of the more common causes of cracking or distortion in overseas fabrication. AASA sources welded components across the materials below, matched to a factory with proven experience in that specific alloy.
- Carbon Stee - lA36 / structural grades
- Stainless Steel - 304 / 316
- Aluminum - 5052 / 6061
- Alloy Steel - 4140, higher strength
- Exotic Alloys - Titanium, Inconel, on request

Direct Factory vs Sourcing Through AASA
Reduce sourcing risks, simplify supplier management, and gain access to a vetted network of welding and fabrication partners across India, China, Vietnam, and Thailand, all through a single point of contact.
Direct Factory
- Limited to the welding processes and equipment of one factory
- Time-consuming supplier research and qualification
- You manage engineering communication
- Quality oversight depends on your internal resources
- Need to coordinate production updates yourself
- Limited alternatives if production issues occur
- You handle supplier negotiations
- Separate management of logistics and export documentation
- Multiple contacts across different vendors
- Higher risk when sourcing from an unfamiliar supplier
AASA Sourcing
- Access to a network of vetted welding and fabrication manufacturers across Asia
- Factory selection based on your part, budget, and quality requirements
- Dedicated sourcing and engineering support throughout the project
- Independent quality inspections before shipment
- Regular production monitoring and progress reporting
- Ability to identify alternative qualified suppliers when needed
- Assistance with pricing, terms, and supplier coordination
- End-to-end coordination, including shipping and export support
- One dedicated point of contact throughout the project
- Reduced sourcing risk through supplier evaluation and ongoing oversight

What welding processes can AASA source for overseas manufacturing?
AASA's factory network supports MIG (GMAW), TIG (GTAW), stick (SMAW), and robotic welding, along with spot and resistance welding for sheet metal assemblies. Factory selection is based on your material, joint type, and production volume.
Can AASA source welding to AWS D1.1 or ASME Section IX standards?
Yes. AASA works with factories holding welder qualifications and procedure qualifications under AWS D1.1 and ASME Section IX, and can request documentation such as WPS, PQR, and welder certifications before production begins.
How does AASA verify weld quality on an overseas order?
Weld quality is checked through in-process visual inspection, dimensional review, and where specified, non-destructive testing such as dye penetrant or ultrasonic testing. A pre-shipment inspection confirms every order against your drawing and spec before it leaves the factory.
Should I choose MIG or TIG welding for my part?
MIG welding is faster and well suited to carbon steel structural fabrication and higher volume runs. TIG welding is slower but produces cleaner, more precise welds, making it the better fit for stainless steel, aluminum, thin materials, and appearance-critical parts. AASA can recommend the right process once we see your drawing and material.
Can AASA source welded assemblies that also require machining or finishing?
Yes. AASA coordinates welded fabrication alongside CNC machining, grinding, surface finishing, and painting, so you receive a finished, ready-to-install assembly rather than a raw weldment you have to route to a second vendor.
Which countries does AASA source welding and fabrication from?
AASA's welding and fabrication network spans India, China, Vietnam, and Thailand. Country selection depends on your material, certification requirements, production volume, and target landed cost.
What information do you need to quote a welded fabrication?
We typically need a drawing or technical specification, material and thickness, weld symbols or joint requirements, any applicable code or certification such as AWS D1.1, estimated quantities, and your target timeline. If you don't have complete documentation yet, our team can still discuss your requirements and help determine what's needed to move the project forward.
