Tensile Properties and Microstructure of Butt Weld of Q235A Steel Made by Wet Welding Process
The effect of underwater wet welding processes with flux-cored wire on tensile properties and microstructure of Q235A steel was studied. Rolled plates of 8 mm thickness have been used as the base material for preparing single pass butt welded joints. OM and SEM were used to analyze the microstructure of the joint and the fractography of the tensile specimen. Tensile test showed that the fracure was occured at base metal and tensile strength could reach 415Mpa.
