...EXPERIMENTAL PROCEDURE Three number of identical test coupons having single V groove, shown in Figure 3 were welded in 1G position with submerged arc welding process using different heat inputs achieved by varying the welding parameters i.e. current (Amp), voltage (V) and travel speed (mm/min...

...Abstract The paper considers best practice to realise the optimum combination of strength, toughness, corrosion resistance and radiographic integrity in UNS S32760 pipe girth welds made using the GTAW process. Aspects of fit up, tacking, root gap are considered. The effect of weld heat input...

... of advantages over a simple V-preparation in reducing the number of passes to complete a joint and thus reducing the overall heat input. This reduces the extent of the HAZ in the base material and may be beneficial in minimising metallurgical reactions and formation of precipitates in the HAZ. At the same time...
