Thornhill Inspection Services Inc. provides Quality Assurance / Quality Control (QA/QC) inspections. We also provide nondestructive inspection to refineries, Offshore platforms and Shipyards for clients across Canada and the United States. Our inspectors are certified to CSA Standard W178.2, and through the Canadian General Standards Board for NDE inspections.

We can provide full time welding quality control or scheduled random site visits to evaluate weld quality at various stages of construction. Our quality control service to you will consist of confirming that all welders hold valid tickets, assuring the proper weld consumables are used, that welding electrodes are stored as per code, proper torque values at bolted connections are met, weld details as stated in drawings are duplicated in the field, completed welds are the required size and length, and that welds conform to the applicable code or standard.
