Abstract
The method of fit-up for narrow-gap TIG welding of 20-100 mm thick titanium plates was developed, providing a high quality of welded joints and substantial reduction of cost of the welding process. Fit-up of plates for welding is performed by using a forming backing, which acts as a mould when making the root pass. The use of backings makes it possible to simplify edge preparation and fit-up of the welded joints, and decrease welding deformations.
