Additive manufacturing technologies based on melting and solidification have considerable
similarities with fusion-based welding technologies, either by electric arc or high-power …

The mass saving potential of light-weight materials, such as Al alloys, is beneficial for fuel
economy and reducing CO 2 emissions. However, the wide-spread use of these alloys has …

Abstract The 7N01-T5 alloy (AT5) and 7N01-T4 alloy (AT4) were butt welded by metal inert
gas (MIG) welding with ER5356 filler wire, and the mechanical properties and corrosion …

Abstract The 7075-T6 aluminum (Al) alloy is a high-strength material with great application
potential. However, the tensile strength and elongation of its arc-welded joints are severely …

Lightweight alloy parts often experience substantial wear, corrosion, or chemical reactions in
service, resulting in significant areal and volumetric defects (Refs. 1, 2). Replacement of …

The effect of repair welding on the microstructure and mechanical properties of the welded
joint was investigated. The results show that the difference of microstructure in different …

Gas tungsten arc welding was used to repair the laser additive manufactured Ti-5Al-5Mo-5V-
1Cr-1Fe (Ti-55511) alloy with a subsequent triplex annealing treatment. The tensile …

In this research, we explore the preliminary effects of processing conditions using a novel
additive manufacturing (AM) process, known as additive friction stir deposition (AFSD), on …

In this study, fine position samples of heat affected zone under single and secondary thermal
cycles were simulated by heat treatment method. The influence of secondary thermal cycle …

The welding with weld reinforcement rolling (WR) process was proposed to improve the
deteriorated mechanical properties of traditional arc welded (TW) joints of the 7075-T6 …
