The Effect of Welding Methods on Temperature Distribution in Steel Components with Composite Lining

The paper presents the comparison of three welding processes, i.e. manual (i.e. hand-held) laser welding without the use of consumables (filler metals), manual laser welding involving the use of a solid wire as the filler metal and manual TIG welding with the solid wire used as the filler metal. Welding tests included measurements of temperature on the root side, i.e. 2 mm and 4 mm away from the weld axis, as well as the comparison of linear welding energy values. The measurement results enabled the identification of the most favourable solution applicable for the welding of steel materials with composite lining.
