High-Strength Low-Alloy (HSLA) steel exhibits excellent tensile strength and ductility, and it also possesses good welding performance due to its low carbon equivalent. However, welding defects always inevitably appear during the fusion weldingof HSLA steel. In this paper, the previous investigations on the microstructure of the joined HSLA steel by different fusion welding processes arereviewed, and the mechanical properties of the fabricated joint are analyzed. Also, the practicability of different fusion welding processes on HSLA steel has been systematically analyzed. Finally, the prospect

In the case of the MAG welding of carbon and low-alloyed steels wires or hollow wires with (rutilic or basic) flux with metallic powder or self-protection are used. In indoors weldings huge quantities of smoke, gases, dust and particles in suspension, etc. get accumulated. These noxious substances produced during the welding process may severely affect the welders health. To improve the welders working conditions, on an international scale, the following are used: welding masks with self-obscurazation and air control; noxious substances vacuum cleaners fitted with filters; MAG welding pistols

The alloy aluminum of 5000 series will have relatively high strength through solid solution strengthening of Mg. However, when laser welding the 5000 series aluminum alloys, the Mg is selectively evaporated by welding heat due to its low melting and vaporization points, resulting in a reduction in the strength of welds.

Abstract:

AbstractGas metal arc welding (MIG welding), as a significant welding method, has continuously evolved and improved alongside the expanding application of titanium alloy materials. This paper reviews the latest research progress in MIG welding and its hybrid welding technologies for titanium and its alloys. It delves into the advantages of MIG welding derivative technologies such as pulsed MIG welding, PMC MIG welding, CMT, and CMT+P, as well as hybrid welding technologies like Hot‐wire TIG, LW‐MIG, and PAW‐MIG, in enhancing welding efficiency, improving weld quality, and addressing the limita

Abstract:

Various methods have been proposed to modify the friction stir welding. Friction stir vibration welding and underwater friction stir welding are two variants of this technique. In friction stir vibration welding, the adjoining workpieces are vibrated normal to the joint line while friction stir welding is carried out, while in underwater friction stir welding the friction stir welding process is performed underwater. The effects of these modified versions of friction stir welding on the microstructure and mechanical characteristics of AA6061-T6 aluminum alloy welded joints are analyzed and com

Abstract:

An all-position welding experimental platform for pipelines was conducted, and metal active gas arc welding (MAG) was used to study the effect of various welding torch tilt angles on the welding quality. Under the same MAG welding parameters, the single-factor experimental method was adopted, and different welding torch tilt angles were selected in the welding experiment based on a grade X80 pipeline. In this study, a double ellipsoid heat source model was built, considering different welding torch tilt angles. Based on the model, the effect of various welding torch tilt angles on the depth an

Abstract:

The development of welding technology in this era took place rapidly, especially in the sector of new ship building and ship construction repair. Incorrect welding activities often cause delays which cause costs, time and consumables losses. In order to develop the speed and efficiency of the welding work, it is mandatory to determine a welding method that is suitable for the site conditions. This study provides a choice of three welding methods consisting of the SMAW and FCAW welding methods based on their strength and economic value. To strengthen the results of welding can be tested with a

Finite element simulation is utilized in an aluminum alloy 2014 butt weld with the three kinds of welding processes, namely the filler wire Tungsten Inert Gas (TIG) welding, the laser welding and laser-TIG hybrid welding. The simulated results are in good agreement with the weld cross sections for the TIG and the laser welding, and basically in agreement with that for the laser-TIG hybrid welding using the actual welding parameters. Furthermore, the simulated results shown that the longitudinal residual stresses after welding are the largest for the laser welding and the laser-TIG hybrid weldi

Automatic welding technology is a solution to increase welding productivity and improve welding quality in offshore pipe welding. To increase welding productivity, it is necessary to save time during the assembly/disassembly of the guide track from the welding carriage and pipe to move the next station. The guide track consists of a pneumatic system that does not separate the welding carriage, and two welding carriages operate on a half-pipe joint to increase productivity. These welding carriages automatically operate under the controller command. An automatic welding system consists of a DC m
