Frequently Asked Questions
Which welding certifications does ACE hold?
We hold AWS D1.1 (structural steel welding) and AWS D1.3 (sheet metal welding) certifications, with PQR-qualified WPS procedures. Our WPS is shared across Suzhou and Penang sites, ensuring identical weld quality at both locations.
What welding processes do you offer?
TIG (GTAW) for stainless steel and aluminum with clean cosmetic beads, MIG (GMAW) for carbon steel production runs, spot welding for high-volume light assemblies, and robotic welding cells for repeatable dimensional accuracy. Laser welding available on request.
Do you perform leak-tight welding for semiconductor gas boxes?
Yes, we regularly weld semiconductor gas distribution boxes with helium leak testing to 10⁻⁹ mbar·L/s standards. All weld seams get 100% visual inspection plus dye penetrant or leak testing per customer spec.
Can you handle large structural welding assemblies?
Yes, we weld large frames up to 3 m × 2 m × 2 m at Suzhou facility. Larger assemblies split into modular sections with match-machined joints. Robotic welding stations available for repeatable production of 20+ identical units.
