Abstract
A method was developed for narrow-gap welding of thick titanium alloys (20-110 mm), having the following advantages: decrease in requirements to edge preparation, reduction of costs for preparatory operations, lowering of angular distortions and residual welding stresses in welded joints, and saving of welding wire and electric power, while ensuring a high quality of the welded joints. Guaranteed fusion of side walls of the groove with the weld is achieved due to application of the controlling transverse alternating magnetic field.
