Abstract
A diode laser-TIG hybrid cladding process was proposed in this study to make further improvement on wettability and spreadability of cladding layer. Cladding layers fabricated with different heat sources were wire-cutted to observe their cross section so as to characterize the wettability. The role of TIG arc in this process is analyzed and illustrated in detail through the cladding process recorded by a high-speed camera. The functions of TIG arc in this process are elevating thermal input to reduce surface tension and exerting extra forces on the melt to help it spread out.
