Journal of Materials Processing Technology, 2014
Abstract A method for accurate, low-cost, lab-scale determination of the optimal collision angles and velocities for collision welding of a given combination of materials has been introduced. 0.508 mm thick grade 2 CP Ti sheets were launched at various velocities toward a Cu 110 target with grooves of angles ranging from 8° to 28°, machined on the ...

International Journal of Refractory Metals and Hard Materials, 2019
Abstract The explosive welding of the axisymmetric 30CrMnSi tube and tungsten alloy rod was studied. Through theoretical analysis, the weldability window of these two metals was obtained, which could enable the prediction of the welding interface morphology under different explosive conditions.

A selectively-coupled shear localization model for friction stir welding process window estimation
International Journal of Machine Tools and Manufacture, 2017Abstract This paper presents a novel computational procedure specifically aimed at gaining modeling capabilities for estimating friction stir welding (FSW) process window. The proposed model first combines a three-dimensional (3D) transient heating effects with a one-dimensional (1D) shear localization process leading to shear band development within

Lower limit law of welding windows for explosive welding of dissimilar metals
Journal of Iron and Steel Research International, 2017The influence of explosive charge thickness on the quality of explosive welding of dissimilar metals was investigated. The lower limit law should be followed in the course of explosive welding. Three welding experiments of stainless steel (410S) and steel (Q345R) were carried out in three different kinds of explosive charge thicknesses, namely 15, 25 ...

Premium Rail Flash-Butt Welding Process Window Based on Phase Transformations
Key Engineering Materials, 2023Currently, heavy-haul and passenger rails are joined by a welding process, which can be either flash-butt welding or thermite. The joining process has increased the overall rails strength, but the welding parameters optimization is tricky and must be performed and studied to improve the weld quality.

Construction of physical welding windows for magnetic pulse welding of 5754 aluminum with DC04 steel
International Journal of Material Forming, 2020Magnetic pulse welding (MPW) has potential applications where fusion welding is problematic, such as in dissimilar joints or where the very part integrity, as in electronic components, is likely to be impaired by hot environments. Mostly suited in lap configuration, its successful implementation hinges on multiple process parameters such as standoff ...

Friction stir welding window for AA6061-T6 aluminium alloy
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2013In this study, friction stir welding window for AA6061-T6 aluminium alloy based on tool rotational speed and weld speed was developed. The formation of friction stir welding/processing zone has been analysed macroscopically and microscopically. Fracture locations of the joints were also analysed using scanning electron microscope.

Welding Windows for Aluminum-Magnesium and Titanium-Steel Explosive Cladding
Journal of Manufacturing Engineering, 2023This study analytically estimated the welding domain for explosive cladding of aluminium-magnesium and titanium-steel combinations. Welding window, an analytical estimation, can ascertain whether the interface is wave-like or straight. The welding window’s lower, upper, left, and right boundaries were constructed using empirical relations suggested by ...
