In considering the importance of avoiding corrosion of weld metal under various environmental conditions, the investigation on the efficiency of different welding methods with various types of electrodes will be inevitable. In this paper, the strength and compatibility of various welding methods were experimentally investigated considering four welding types, including arc welding with phosphor bronze electrode, arc welding with steel electrode, oxy-acetylene welding with bronze electrode, and oxy-acetylene welding with brass electrode. In this regard, firstly, the material properties of base metal were determined by tensile testing, and then the behavior of 46 test samples were examined under three loading conditions of tensile, shear, and bending. investigation of the experimental results showed that with an acceptable approximation, the strength of arc welding with steel electrode could be considered the same in all thicknesses, and the effect of thickness on the tensile strength of the weld could be ignored. That is while the plate thickness has a remarkable effect on the quality of the oxy-acetylene welding. Also, the results of experiments showed that arc welding with steel electrodes in different types of samples has higher strength than the other three types of welding, and then the strength of arc welding with phosphor bronze electrode is in the second grade.
