Model of Layered Weld Formation Under Narrow Gap Pulse Welding [PDF]
IOP Conference Series: Materials Science and Engineering, 2016 The model parameters of narrow gap pulse welding can be divided into input, internal and output ones. The breadth of gap, that is, clearance breadth between upright edges is one of key parameters securing high quality of a weld joint. The paper presents theoretical outcomes for the model of layered weld formation under narrow gap pulse welding.

Weld Formation in Microgravity.
ISIJ International, 1998 In order to investigate the effect of gravity on the formation of a weld, gas tungsten arc (GTA) welding was performed both in a microgravity environment and in a terrestrial environment. The microgravity environment was produced for 10 sec with less than 10-5 G by a drop-shaft type microgravity system at Japan Microgravity Center (JAMIC). The material

Formation of α’ titanium welds by friction stir welding
Journal of Physics: Conference Series, 2020 Abstract In the present study, investigation of the macrostructure of α’ titanium alloy weld produced by the friction stir welding has been carried out. The welding process modes were also selected. It is shown that in case of insufficient load on the tool, an open weld defect is formed.
