The first papers on the activating flux application appeared already in 1950’s and 1960’s, but the interest for this welding process has been activated again in the last ten years 1, 2 . In order to increase the efficiency and productivity of TIG process, a variant of process with the activating flux is applied (ATIG). With the presence of the activating flux and high temperature, the value of ...

In most forming processes based on tailored blanks, the tool material remains the same as that of sheet metal blanks without tailored properties. A novel concept of lightweight construction for deep drawing tools is presented in this work to improve the forming behavior of tailored blanks. The investigations presented here deal with the forming of tailored blanks of dissimilar strengths using t...

Fillet welds of highly reflective materials are common in industrial production. It is a great challenge to accurately locate the fillet materials. Therefore, this paper proposes weld identification and location method that can overcome negative effects high reflectivity. The proposed based on improving semantic segmentation performance DeeplabV3+ network for structural light noise, and, with M...

Friction stir welding and tungsten inert gas welding techniques were employed to weld armor grade aluminum alloy to investigate the effect of welding processes on tensile behavior of weld joints. Tensile tests, Vicker microhardness tests and optical microscopy were performed on developed weld joints and base metal. Welding process influenced tensile behavior and microstructure of weld joints. F...

Precise measurement of a stress-free reference lattice parameter is vital in the determination of residual stress by diffraction techniques using /2-based analyses. For the evaluation of the residual strain profile in fusion-welded material, it is particularly important to correct the measured strain point-by-point by a stress-free reference for each spatial location across the weld. This is ...

When evaluating the safety of steel structures, welding residual stress is used as secondary load and if there any restraint, yield base material for load, regardless size restraint. Of late, members increasing with increase in use high-strength steels, proportion total during evaluation structures increasing. Therefore, it necessary to investigate effect restraint on stress, determine reasonab...
