Improving Welding Quality on Zacns 98 m³ Wagon Underframe

The Zacns 98 m wagon is a wagon with a tank intended for the transportation of dangerous goods in a liquid state.Accidents caused by faulty production can have serious consequences for material goods and human health.It is therefore necessary to pay particular attention to the quality of the production process.The wagon itself consists of two parts: the tank and the underframe.These and other components are joined together using welding technology.The quality of the weld seams on the underframe, in particular the weld seams that belong to weld seam quality class CP B1 or CP B2 according to the HRN EN ISO 15085-3 standard, is the focus of the quality assurance system.Non-destructive surface and volume tests must be carried out on such weld seams and the results, which indicate problems in the welding process, must be closely monitored.This article presents welding and quality control systems for CP B1 and CP B2 performance class welds.In addition to the technologies of welding and quality control, the authors intend to show the quality level over a longer period and propose measures to improve it.The experimental study was carried out in the company uro akovi Specijalna Vozila from Slavonski Brod.
