Transport Canada
Approval

Acorn Welding is a Transport Canada Civil Aviation approved Maintenance Organization #100-91. We are also one of the very few EASA approved Welding Facilities. Our approval Number is EASA.145.7212.

We are also a Transport Canada Civil Aviation approved manufacturer. Acorn Welding holds ratings for Welding, Components, NDT, and Structures as well as distribution of aviation parts. For your convenience our approval certificates are provided online.

03

Product / Process
Control

Acorn Welding utilizes a state-of-the-art ERP-MRP solution to fully control your product, processes, and requirements. Each Customer process and corresponding work instructions are set up in our system. All drawings, specifications, tooling, and individual part requirements are loaded into the corresponding item configuration. Our ERP-MRP solution ensures full material traceability from time of receipt all the way to delivery of the part.

04

Welding Lab

Our Certified in-house lab allows us to prepare, etch, and examine welds to the AWS D17.1:2017 and AWS D17.2:2019 Standards. Having this capability in-house not only allows us to reduce the lead time on weld schedule validation but allows us to fine tune the welding process to reduce the number of weld rejects.

Our Metallurgical Lab utilizes EDM cutting equipment to accurately cut and prepare weld samples for metallurgical examination. A certified etching process is used to enhance the weld features to ensure sufficient weld penetration is present. A Calibrated Computer assisted digital microscope is used to measure and record the results. Results are validated by 3rd parties where required.
