Customized Aluminum Sheet Metal Welding Parts Cnc Precision Machining Service

Product Description

Crida delivers precision sheet metal welded assemblies engineered for critical applications in automotive, medical, and industrial sectors. Our expert welders utilize advanced laser, TIG, and MIG processes to join laser-cut components with exceptional accuracy (±0.05mm positional tolerance), ensuring structural integrity and leak-proof performance. All welds undergo rigorous quality validation through visual inspection, dye penetrant testing, and CMM alignment checks to meet ISO 13485 and IATF 16949 standards. We specialize in complex geometries—from thin-gauge enclosures to load-bearing chassis—with distortion control techniques that preserve dimensional stability. Complementary in-house services include CNC forming, surface finishing (powder coating, passivation), and full material traceability. Backed by DFM-driven welding procedure specifications (WPS) and weld sample validation, Crida guarantees repeatable, compliance-ready assemblies that perform reliably in demanding environments.

Advantages

1. Micro-Precision Welding (±0.05mm Tolerance)
Advanced laser/TIG processes ensure pinpoint accuracy in critical joints, ideal for medical instruments and aerospace assemblies.

2. Industry-Compliant Quality (ISO 13485/IATF 16940 Certified)
Full traceability, weld procedure specifications (WPS), and destructive/non-destructive testing for regulated sectors.

3. Superior Structural Integrity
Optimized heat control prevents warping while achieving >95% base material strength in load-bearing applications.

4. Leak-Proof Seals for Fluid Systems
Porosity-free welds validated through pressure testing (up to 150 PSI) and dye penetrant inspection.

5. End-to-End Integrated Manufacturing
Seamless workflow from laser-cut blanks → CNC forming → precision welding → certified surface finishing.

6. Distortion-Controlled Complex Geometries
Fixturing expertise and pulsed welding techniques maintain dimensional stability in thin-gauge (<0.5mm) assemblies.
