Abstract
The report describes work carried out as part of an on-going collaborative effort between DREP and CANMET's Metals Technology Laboratories aimed at establishing a database for guidelines and specifications for joining high-strength steels. The results of this investigation show that both high yield strength and good low temperature toughness can be successfully achieved in Pulsed Gas-Metal-Arc welds deposited using commercially-available solid and metal-cored electrodes and gases, provided that appropriate welding techniques and parameters are employed. In the case of Submerged-Arc welds, slight lower, but generally acceptable mechanical properties were achieved, although limiting energy input may be required to produce consistently adequate yield strength and toughness. These results are explained in terms of resultant microstructures formed in the respective welds. The influence of energy input (cooling time) and the amount of oxygen and sulphur were also identified as important factors.
