Abstract
The main purpose of this study, the fabrication of tube-to-tube sheet welds ofan acid cooler exchanger, which is produced with stainless steel material, was examined usingdifferent welding methods. The tubes were subjected to two different welding methods usinga tungsten electrode. In orbital welding, the machine places the tube on a mandrel andautomatically performs the welding based on the manually inputted tube diameter. At the endof each tube weld, the mandrel is transferred to the next tube by the welder. In manualwelding, the entire tube-to-tube sheet weld is performed by the welder. Welds were madeusing the same material, same diameter, and same thickness of tubes for both orbital welding and manual welding. As a result, the test results and quality controls for both weldingmethodswere examined.
