Abstract
Spiral welded pipes of 1016 mm diameter and 8.80 mm thickness, made of St 44.2 (DIN 17100) structural steel and commonly used for drinking water pipelines were joined via coated electrodes through manual arc welding. In the welding process, cellulosic electrodes of three different brands were used, after which non-destructive and destructive testing methods and metallurgical probing were carried out for the parts joined. In this study, welding metal, fusion lines, heat affected zones and base material micro structural variations were experimentally investigated as well as tensile, hardness and bending tests according to electrode brands used for welded parts and interpreted through existing literature on the subject.
