Microstructure development in impact welding of a model system

open access: yesScripta Materialia, 2019
Characteristic features of impact welding were investigated in a simple model system of colliding copper single crystals. Large grained sheets were used to approximate single crystal to single crystal impact. Optical microscopy and electron backscatter diffraction (EBSD) analyses showed multiple features of the weld interface, which include deformation

THE IMPACT OF THE INTERNAL WELDING DEFECTS ON THE JOINT STRENGTH

open access: yesTRANSPORT, 2008
The paper looks at the impact of the internal welding defects on the strength of joints. The tension tests provided the values of the welded joint strength limits depending on the area of sporadic voids, slag intrusions and the field of discontinuities.

Optimising the laser-welded butt-joints of medium carbon steel using RSM [PDF]

open access: yes, 2005
The optimization capabilities in design-expert software were used to optimise the keyhole parameters (i.e. maximize penetration (P) and minimise the heat input, width of welded zone, (W) and width of heat affected zone (WHAZ)) in CW CO2 laser butt ...

High Strength and Fatigue Resistant Welds in NiTi and Brass by Impact Welding

open access: yes, 2021
Abstract Vaporizing foil actuator welding (VFAW) was used to create high strength and fatigue resistant dissimilar welds between NiTi and a brass alloy for the first time. VFAW uses the high pressure resulting from a vaporized aluminum foil to impact weld NiTi to brass. Advanced techniques were used to characterize the structure, mechanical and
