In-service welding & materials engineering

Engineering-led in-service welding and hot tapping support for live pressurised systems — including operating pipelines. Services cover WPS/PQR development, hydrogen-assisted cracking and burn-through risk assessment, pipeline sleeve and repair welding, welding automation, and materials engineering advisory.

TES Canada provides in-service welding engineering for operators who need to perform welding on pressurized pipelines or equipment without full depressurization or shutdown. In-service welding is not simply welding while operating — it requires engineering assessment of burn-through risk, hydrogen cracking risk, heat input, cooling conditions, material chemistry, restraint, and post-weld inspection requirements. Our approach ensures that in-service welding decisions are engineered, documented, and verifiable.
