• A number of techniques based on the shielded metal arc welding process have been developed to modify the microstructure of both weld metal and heat affected zone (HAZ) in order to improve the as-welded fracture toughness. In this work, a comparative study was carried out for different repair welding techniques to determine the optimum values of mechanical properties, which can be obtained to identify, the best repair welding techniques. Also, the effect of repeated repair welding on the mechanical properties was investigated to establish the optimum quality of repair welding without post weld heat treatment (PWHT). High strength low alloy structural steel grade 52/3, 40mm thickness was selected for this study. The present experimental results showed that the two-layer repair welding technique is superior among the various repair-welding techniques investigated.
