Welding & Assembly Capabilities
Welding and assembly is a broad manufacturing capability that joins individual metal components into complete assemblies and structures. Welding processes include MIG (GMAW), TIG (GTAW), stick (SMAW), flux-cored (FCAW), resistance (spot and seam), and specialized processes like laser welding, electron beam welding, and friction stir welding. Assembly services include mechanical fastening, riveting, adhesive bonding, brazing, and soldering. Modern welding shops employ certified welders (AWS, ASME), robotic welding cells for production, and comprehensive quality systems including destructive and non-destructive testing. Welded assemblies are found in virtually every industry.
±0.015"-±0.030" typical for welded assemblies; fixturing improves accuracy
5-15 business days for prototypes; 3-8 weeks for production
$50-$5,000+ per assembly depending on complexity

Welding & Assembly in San Jose — FAQ
How many Welding & Assembly providers are in San Jose, CA?
The San Jose-Sunnyvale-Santa Clara metropolitan area has approximately 2,800 manufacturing establishments, many of which offer welding & assembly services. The area employs about 65,000 manufacturing workers, ensuring a skilled workforce for your project.
What welding certifications should I look for?
Key certifications include AWS D1.1 (structural steel), AWS D1.2 (aluminum), AWS D17.1 (aerospace), ASME Section IX (pressure vessels), and NADCAP (aerospace quality). Ensure the welding shop has certified welders and documented welding procedures (WPS).
What is the difference between MIG and TIG welding?
MIG welding is faster and easier to automate, ideal for production and thicker materials. TIG welding provides higher quality, cleaner welds with more control, ideal for thin materials, visible welds, and critical applications like aerospace and medical.
Can robotic welding handle small batches?
Robotic welding excels at medium-to-high volumes. However, modern collaborative robots (cobots) and offline programming have made robotic welding more economical for smaller batches (50+ parts). For true prototypes and one-offs, manual welding is more practical.
What testing is done on welded assemblies?
Non-destructive testing (NDT) includes visual inspection, dye penetrant, magnetic particle, ultrasonic, and radiographic testing. Destructive testing includes tensile, bend, and impact tests on sample coupons. Critical applications (aerospace, pressure vessels) require certified NDT.
