The process of welding sheet metal parts

The process of welding sheet metal parts with large thicknesses (>100 mm) requires the introduction of a significant amount of heat 🔥 into the welded material. In addition to the obvious preheating, it is also necessary to gradually cool ❄️. After this stage, we conduct preliminary ultrasonic and magnetic particle tests on the welded lifting columns.🔍These are preliminary tests, as our role does not end at this stage - the parts are then subjected to PWHT heat treatment. After annealing, the tests are repeated, as required by the 📜 regulations, which make it mandatory to conduct final tests after the last stage of processing.
