摘要

This study investigated the application of narrow gap welding for titanium alloy samples with variable thickness, employing a controlled magnetic field to enhance process stability and weld quality. This work explores the influence of a controlled magnetic field on arc behavior and heat distribution during narrow gap tungsten inert gas (TIG) welding of samples with thicknesses ranging from 45 to 60 mm. The work demonstrated how the different thickness at the start and at the finish of the welded detail impacted welding modes and heat source parameters. Results of investigations of the macrostructure of the welded joints as well as dependency of welding current and the height of surfaced metal layer were presented.
