All weld technicians at Aircraft Ducting Repair are certified to AMS-STD-1595 and BAC5962. All gas tungsten arc welding, often referred to as heli-arc welding and tig welding, is done in accordance with AWS D17.1. Each new weld technician at ADR receives both classroom training and on-the-job training (OJT). Classroom training begins immediately during orientation with each weld technician receiving a copy of ADR’s Employee Training Manual. This document covers, in depth, many of the welding situations encountered on a daily basis, including grinding, fitting, cleaning, purging, tacking and welding on a wide variety of metals. Depending on each weld technician's level of expertise, the classroom and OJT phase may last from two weeks to two months.

After completing the training phases, each technician is required to weld and submit test samples for independent certification in all groups necessary for the work to be performed at ADR. These groups include material certification for 2219, 5052, 6061 and L82 Aluminum; Hastelloy X; Inconel 600, 625 and 718; 304, 321, 347 15-5PH, 17-7PH and S527 Stainless Steel; Commercially Pure and 6AL-4V Titanium; as well as other alloys.

Once a weld technician has passed their group certifications they are approved for welding aircraft parts in only the groups for which they are certified. Every technician at ADR, as monitored by the QA Department, continues to receive recurrent training and is re-certified as prescribed per AMD-STD-1595 and BAC5962.
