Abstract
In this research, an attempt is made to repair copper parts that are widely used in industry, electrical appliances and etc. using melting method. This is very challenging and it causes defects such as in hot cracks, thermal stresses and residual stresses and in order to prevent these defects the friction method is used.in this research, in order to repair copper parts using friction process have been used in 3 different ways and after welding, welding has been investigated in term of hardness and stresses, metallographic properties and crystal structure. in order to examine the weld in terms of mechanical and metallurgical properties, the following test were performd:1-hardness test 2-tensile test 3-metallography 4-prepration of SEM images and elemental analyze of EDAX. 5-inspection of welding and check the lacks 6-surface quality after welding and repairing 7-performed the XRD test to check the crystal structure and check phase changes in welding were investigated and results were presented. The result of this research shows these parameters have straight effects on the quality and properties of welding, including, changing in distance between crystal plates and changing in crystal structure and increasing in hardness of welding surface because of friction of tool with the work piece and temperature increase at this position.
