The application of press hardening steels is spreading from automobiles, where crashworthiness demands are critical, to other segments, such as the agricultural and road transport industries. However, operational conditions which equipment exposed requires heavier sheet gages adapted joining processes. In this context, fatigue recognized critical failure mode. present article describes procedur...

The welding task in double-hulled structures in shipyards and in steel-frame structures is hazardous and difficult due to the toxic gas and limited workspace. Therefore, many efforts have been undertaken for automation. The main challenge for automation is the development of a simple and robust seamtracking algorithm that can be applied to a portable welding robot that operates under irregular ...

The objective of this research is to develop an experimental-theoretical analysis about the 11 influence of the cooling medium and the geometry of the welding bead profile in fatigue life and 12 associated parameters with structural integrity of welded joints. A welded joint with cruciform 13 geometry is considered using SMAW, plates in structural steel ASTM A36 HR of 8 mm of 14 thickness and E...

The development and fabrication of fusion reactor components utilize different grades of stainless steel materials and different welding techniques. Major candidates are TIG welding, Laser welding and Electron beam welding and Narrow Gap TIG welding. The weld joints quality evaluation and their mechanical properties are to be analyzed for performance of these developed components. The welded jo...

The weld pass sequence generally affects residual stress profiles. In this study, the residual stress profiles of bead on plate specimens were analytically and experimentally examined. The material used in this study was the low alloy steel SQV2A (JIS G 3120), which is equivalent to ASTM A533. Phase transformation usually occurs around the welded area in SQV2A and also affects the residual stre...

The aim of the present study was to determine whether there is a difference in toxicity and loss of viability of three-dimensional (3D) reconstructed human oral epithelium (RHOE) cell cultures induced by point-welded (PW), laser-welded (LW), and silver-soldered (SiS) orthodontic wires. Three types of soldered stainless steel (SS) wires: PW, LW, and SiS were prepared (n = 3) and subjected to mul...

The effect of the microstructure heterogeneity on the tensile plastic deformation characteristic of friction-stir-welded (FSW) dual-phase (DP) steel was investigated for the potential applications on the lightweight design of vehicles. Friction-stir-welded specimens with a butt joint configuration were prepared, and quasi-static tensile tests were conducted, to evaluate the tensile properties o...

in the present study, the microstructure and mechanical properties of the dissimilar welding betweenastm a335 low alloy steel and er309l austenitic stainless steel were investigated using the gastungsten arc welding process. the welding of dissimilar materials between astm a335 low alloy steeland er309l austenitic stainless steel was found to have a significant effect on the microstructure when...
