Evaluation of Cold Spray Process for Solid-State Welding
Welding is an important manufacturing process used in various industries, from automotive to aerospace. However, existing welding techniques have certain drawbacks that affect weld integrity and limit their use in joining some temperature-sensitive materials. A significant concern is the …

Exothermic flux forge welding of steel tubulars
Welding processes inevitably alter the local microstructure and in turn affect the properties. For many grades of steels that require high strength, ductility, and toughness, it is difficult to maintain this combination of properties after welding. While full part heat treatments can sometimes be …

Solid-state joining of titanium alloy to stainless steel
… a titanium alloy, Ti 1.2 ASN, were made by the solid-state welding methods of vaporizing foil actuator welding (VFAW) and mash seam resistance welding (MSW). A Nb interlayer was used in the MSW process as a diffusion barrier due to the relative higher heat input and longer welding time in …

Modelling of friction stir spot welding
Friction stir spot welding (FSSW) is a solid-state welding process which is especially useful for joining precipitation-hardened aluminium alloys that undergo adverse property changes during fusion welding. It also has potential as an effective method for solid-state joining of dissimilar alloys. …
