An evaluation of weld metal nitrogen retention and properties in 316NL austenitic stainless steel [PDF]
, 2011 A series of tests were conducted using varying levels of nitrogen and helium in a conventional argon shielding gas when welding 316LN austenitic stainless steel. The outcome was that a 15 per cent nitrogen addition to the argon shielding gas had the most

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

Investigation of metal flow in bridge die extrusion of Alloy 6063 and subsequent effect on surface quality and weld seam integrity [PDF]
, 2013 This paper describes a detailed study of tube extrusion by simulation using finite element method (FEM). The finite element model used one-sixth of symmetry. The extrusion load, emperature evolution and metal flow were predicted.

Fault welding by pseudotachylyte formation [PDF]
Geology, 2016 Abstract During earthquakes, melt produced by frictional heating can accumulate on slip surfaces and dramatically weaken faults by melt lubrication. Once seismic slip slows and arrests, the melt cools and solidifies to form pseudotachylytes, the presence of which is commonly used by geologists to infer earthquake slip on exhumed ancient ...
