TL;DR: In this article, a detailed experiment of CO2 laser-Tungsten inert gas (TIG) hybrid welding with different shielding gas methods was carried out on the 316L stainless plate, and the results demonstrate that full weld penetration denoting efficient synergetic effect only can be obtained under the appropriate shielding gas parameters.

TL;DR: In this paper, the effect of the thermal cycle during friction stir welding (FSW) on the microstructure and mechanical properties of a Ti-6Al-4V alloy joint was investigated by welding 2mm-thick alloy plates together under various conditions.

TL;DR: In this article, an autogenous gas tungsten arc welded P92 weld joint was subjected to two different post weld heat treatment (PWHT) procedures, which reduced the heterogeneity gradient along the weld cross section.

22 Jan 1997TL;DR: An article made of a nickel-base superalloy having a nilductility range from the solidus temperature of the alloy to about 600° F. is welded, as for example in the weld repair of surface cracks, by removing foreign matter from the area to be welded as discussed by the authors.
Abstract: An article made of a nickel-base superalloy having a nil-ductility range from the solidus temperature of the alloy to about 600° F. below the solidus temperature is welded, as for example in the weld repair of surface cracks, by removing foreign matter from the area to be welded, first stress relieving the article, adjusting the temperature of the article to a welding temperature of from about 1800° F. to about 2100° F., welding a preselected area in an inert atmosphere at the welding temperature, and second stress relieving the article. Welding is preferably accomplished by striking an arc in the preselected area so as to locally melt the alloy in the preselected area, providing a filler metal having the same composition as the nickel-based superalloy of the article, and feeding the filler metal into the arc so that the filler metal is melted and fused with the article to form a weldment upon solidification.
