Abstract
Similar Plates of stainless steel (AISI 316L) and dissimilar plates of stainless steel (AISI 316L) and low carbon steel (Ck15) are welded by brazing using copper base non- active filler metal alloys in furnaces with inert gas atmospheres The specimens were inserted in special container called (Retort) filled by inert gas(argon) during brazing process with flow rate (1-2 litter / min). Three types of filler metal alloys DINL- Ag20Cd , AWSRB CuZn-C , AWS RB Cu Zn – D were used with changing the brazing time (5 , 10) min at given temperature suitable for each filler metal alloy . Many or various mechanical and metallurgical tests were carried out including single shear test, double shear test and tensile shear test, in addition to the microstructure and x-ray diffraction inspection for each similar and dissimilar welds. It was shown that single and double butt joints of the similar metals of stainless steel (316L) showed higher shear strength than that of dissimilar weld of stainless steel (316L) and Low carbon steel( CK15) . The brazed joints by filler metal alloy (RBCu Zn-D) showed the best shear strength for similar and dissimilar metal of stainless steel (316L)and low c brazing time arbon steel (Ck15) in comparison with joints brazed by other filler metal alloys at (5, 10) min .
