Inverstigation of mechanical properties of dh 36 ship steel sheets welded by various welding methods

In this study, mechanical and microstructural affects of various welding methods on materials were investigated. The optimum process parameters were tried to determine. Advantages and disadvantages of different welding methods were discussed. The welding methods studied here are electric arc welding,gas metal are welding and shield arc welding.In this study, the specimens were exposed to tensile test, bending test, impact test and microstructures were determined did their microhardness values were measured. The ductile to brittle temperature was determined as 0-20°C.
