Solid State Impact Welds Between Dissimilar Metals Utilizing Vaporizing Foil Actuators: A Microstructural Evaluation

AN EVALUATION OF THERMAL STABILITY IN DISSIMILAR WELDS BETWEEN 310 STAINLESS STEEL AND ALLOY 657

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

Vaporizing foil welding: A new tool for collision welding

A new method for implementing collision welding at a laboratory scale has been developed. The pressure that drives the flyer plate toward the target is created by electrically driven rapid vaporization of a thin metallic conductor, rather than by chemical explosives or magnetic forces. Dissimilar welding couples of copper-titanium, copper-steel, aluminum-copper, aluminummagnesium and titanium-s...

Mechanical Properties of Dissimilar Welds between AISI 4130 and GOST09ch16N4B

Mechanical properties of dissimilar weld joints between GOST09ch16N4B (a martensitic stainless steel) and AISI 4130 thin sheets made by gas tungsten arc welding (GTAW) were studied using ER410NiMo and ER100S-G filler metals in post weld heat treated conditions. Heat treatment cycles consisted of austenitization at 900, 950 and 1000 °C for 1 h and this was followed by oil cooling and tempering a...

A Comparative Evaluation of Welding Consumables for Dissimilar Welds between 310 Austenitic Stainless Steel and Inconel 657

The current work was carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials; the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steels 310. Of the two joints involved, this paper describes the choice of welding consumables for the...
