Abstract
In this research brazing process was done by using Electrical Arc as a heating source to join stainless steel sheets Type (304L) together. The brazing process was accomplished by using silver brazing filler metal tetra composition alloy (Ag-Cu-Zn-Cd). The brazing variables were heat quantity (as welding electrical current) and clearance between the two joined base metals. After finishing brazing there were three destructive tests to find out mechanical and phase transformation which happened during the operation. The first was tensile test and the second was micro-hardness testing by preparation specimens and testing them and the third test was micro examination test by taking micro photos of sections of brazing joints maximum tensile strength was 185 MPa at current of (15) ampere with clearance of (0.125) millimeter for stainless steel sheet thickness of (1.5) millimeter and the prepared specimens whivh (V) chamfered were batter than non chamfered specim
