As improving fuel economy and performance through weight reduction in vehicles are recognized as important tasks, the defense industry is researching ways to reduce of armor plates for combat increase bulletproof durability. Most manufactured using weld joints. High-hardness (HHA) used make plates; however, its mechanical properties deteriorate because hydrogen embrittlement high-temperature so...

In the present study, Gas metal arc welding (GMAW) based Wire-arc additive manufacturing (WAAM) process was used to fabricate a multi-layered structure at optimized parameters on SS316L using wire of SS316L. The structure's microstructure, macrostructure, and mechanical properties (tensile test, impact microhardness, fractography) were examined three locations top, middle, bottom sides structur...

In this research, the effect of vibration at the resonant range (75 Hz) on the hardness and tensile strength of AA-5083-H321 aluminum alloy, were welded by gas metal arc welding (GMAW) investigated. Vibration forces were ranged from 850 N to 2200 N, under identical welding parameters. Tensile strength and hardness testing of welded samples were performed. After mechanical tests, the fracture su...

Abstract Invar, also known as FeNi36, is a material of great interest due to its unique properties, which makes it an excellent alternative for sectors such tooling in aeronautics and aerospace. Its manufacture by means wire arc additive manufacturing (WAAM) technology could extend use. This paper aims evaluate the comparison two most widespread WAAM technologies: plasma welding (PAW) gas metal...

Abstract The study presents a data-driven framework for modelling parameters of hardfacing deposits by GMAW using neural models to estimate the influence process without need creating experimental samples material and detailed measurements. GAS Metal Arc Welding (GMAW) does sometimes create non-homogenous structures in not only deposited material, but also heat-affected zone (HAZ) base material...
