Abstract
This paper has focused on the joint type effect on the creation and gradient temperature of weld metal in the welded pipe. The main purpose is to reduce the heat generated in the weld metal and the temperature gradient in the pipe thickness direction, by joint type Changes. To obtain a suitable joint type, different joint types have been studied experimentally and numerically by Comsol software. By using destructive and non-destructive tests, the mechanical properties, such as the ultimate tensile strength and the elongation of the weld metal, have been investigated. Evaluation of the metallurgical properties, for instance, the grain boundary and the enlargement of the heat affected zone, has also been examined. The results show that changing the joint type reduces the generated temperature 19% and the temperature gradient in the weld metal. Follow it, the grain boundaries increase and a rectangular weld metal profile is created. Increases the ultimate tensile strength 5% but not obvious change in elongation.increases the ultimate tensile strength by 5%.
