The HOSAB-2 factory makes the bodies for the KARSAN-branded JEST, ATAK, and ATA minibuses and buses. Production is made by joining shaped metal sheets and profiles on a separate welding fixture for each vehicle, mainly using the gaseous sub-welding method.
The responsible units check and monitor all process parameters (current, force, timing and coolant system), process descriptions, and plant equipment against the check plans. All products made in the welding workshop are subjected to destructive and non-destructive tests at specific intervals and spot welding checks are carried out. The dimensional accuracy of the produced bodies is measured using a 3D measuring device at the intervals specified in the quality plans. Once they are made, the bodies undergo quality control checks before being sent to the Paint Section.
