INTRODUCTION The welding stresses introduced into the structures due to welding sometimes increase to higher values ​​as the yield strength of the material.. The problem of welding stress was not taken seriously until the construction of large structures by fusion welding. However unwanted internal stresses may reduce the endurance limit of individual parts. But these […]
