DRIWELD--THE MOST PRACTICAL TECHNIQUE FOR CODE QUALITY UNDERWATER WELDING

The paper presents the results of experience with the DriWeld technique developed by British Oxygen Company for offshore repair and construction. The principle of the technique is to create an inert, stable gas envelope around the weldment and the welding gun using a localised dry chamber. Some mechanical test results of butt welds made using the DriWeld and a pulsed-arc welding process at depths down to 140 feet are given. The metallurgical properties of these welds are normally identical to those expected from similar surface welds and hardness values are rarely in excess of 300 DPN. Further development of the DriWeld system toward operation in deeper waters is reviewed. Order from: BSRA as No. 48,086.
