Sourcing Welded Assemblies in United States
What an industrial buyer needs to know before requesting quotations for welded assemblies from United States-based suppliers.
Overview
Sourcing welded assemblies from United States is one of the recurring decisions of any industrial buyer who needs to balance unit cost, quality control and lead time. This page collects what an EU buyer should know before opening a Request for Quotation for welded assemblies suppliers in United States: typical materials, tolerances expected on the drawing, certifications worth asking for, current price positioning and shipping turnaround.
From a pure cost angle, United States prices welded assemblies roughly 30–50% higher compared to the average European baseline. Real numbers depend on volume, alloy and surface treatment, but this gap is what justifies a sourcing exercise toward United States in the first place. Cost is rarely the only variable: lead time, audit access, certifications and supplier capacity at the right volume usually decide which suppliers actually make the shortlist.
A typical first article from a United States-based welded assemblies shop takes 14–60 working days, plus 10–18 shipping days of shipping to central Europe. Series production lead time depends on volume and capacity reservation: most established shops want a forecast horizon of 60 to 90 days to plan raw materials and surface treatment subcontractors.
When to choose this process
Use for low-to-medium volume sub-assemblies where casting or forging would be uneconomic.
Welded assemblies combine cut, formed and machined components into structural sub-systems: frames, skids, tanks, pressure vessels. Quality lives in the welding procedure (WPS), qualified welders and post-weld treatments.
Why source here — United States
- Most advanced certified processes (NADCAP, AS9100D, FDA)

Frequently asked questions
Is it worth sourcing welded assemblies from United States?
It pays off when the lower hourly rate (30–50% higher) beats the logistic friction (10–18 shipping days) and the selected supplier holds the required certifications (ISO 9001, AS9100D). Below ~200 pcs/year it often doesn't; above ~1,000 pcs/year the math almost always tips in favour.
Do I need to provide the WPS?
No. Send drawing + material + service conditions; the supplier issues WPS/PQR and welder qualification records for your approval.
Why source from the US as an EU buyer?
For AS9100/NADCAP aerospace parts feeding US programmes, FDA-cleared medical devices for the US market, or semi-conductor equipment with US-content rules.
