Abstract: This research deals with the welding technology of copper pipes which is mainly used in refrigeration systems and boilers. The chemical composition of this metal confirms that is to pure copper (≥99.99 Cu). This metal shows an excellent weldability. Oxyacetylene welding process with silver filler is used to join two pieces of copper pipes. Weld inspection for all welded samples involves the evaluation of the integrity and mechanical prosperities of the weld joint. That was conducted using several destructive and non-destructive tests on the weld joints such as, Tensile, hydrostatic, x-ray and Liquid penetrant tests). These tests procedure reveals that, the weld joint maintain a good mechanical properties and acceptable weld defect.
