Summary: Quench and tempered (Q&T) steels are widely used in the mining and defence industry, but they are prone to hydrogen assisted cold cracking (HACC), which requires careful selection of consumables and skilled welder to fabricate defect-free structures. The introduction of modified pulsed arc mode of depositions has improved productivity rates and can be used by welders with greater skill variations.

Summary: Aluminum gas metal arc welding (GMAW) uses inert shielding gas to minimize weld defects. For aluminum shipbuilding, the use of helium-argon mixtures or pure helium shielding gas is recommended, but helium is costly. The rotating electrode pulsed GMAW process can improve argon shielding fusion characteristics and reduce helium usage.

Summary: Gas Metal Arc Welding (GMAW) technology has expanded in various areas in recent years, but faces challenges in selecting appropriate welding parameters, particularly in dissimilar metal welding. This paper surveyed different GMAW standards to select suitable parameters for welding dissimilar nonferrous metals, and explored advancements in GMAW for non-ferrous welding. By controlling heat input and post-heat treatments, adequate joint properties can be achieved to widen the utilization scope of GMAW in automated large-scale manufacturing.

Summary: Metal additive manufacturing (MAM) techniques, especially wire arc additive manufacturing (WAAM), have made significant advancements in the past decade and have become a promising method for producing metallic materials in industries such as aerospace, marine, and automotive. WAAM offers high deposition rates, low production time, and flexibility in part size, making it highly efficient and cost-effective. This review article thoroughly discusses various process parameters and optimization strategies to address challenges in WAAM, such as corrosion, residual stresses, cracks, spatter, deformations, delamination, oxidation, and porosity. The article also highlights current trends and future directions for WAAM research.

Summary: Thermomechanically cold processed (TMCP) steels with high strength are widely used in constructions due to their fine-grained structure and low carbon content. However, the welding technology for such steels poses challenges, mainly due to the complex behavior of TMCP structure under the welding thermal cycle effect.

Summary: Weld evaluation is typically done after the welding process, which may result in material waste and lengthy repairs. Manual inspections are also often required even for automated welds. Therefore, there is a need for a real-time weld quality monitoring method with a decision-making strategy to improve productivity and automation in welding.

Summary: The aim of this study is to investigate the effect of varying filler composition on the microstructure and mechanical properties of dissimilar metal welds of P92 steel and Inconel 617. Shielded metal arc welding technique was used to prepare the dissimilar joint using electrode metals of Inconel 617, Inconel 625, and Inconel 82. The results showed that there were no cracks in weldments obtained by Inconel fillers. The microstructural characterization revealed the presence of different phases in each weld. The tensile test showed that ENiCrCoMo-1 weld had the highest ultimate tensile strength, while ENiCrFe-3 weld had the lowest. Hardness varied in different areas of the weld joint. Microstructural characterization and mechanical testing confirmed that ENiCrCoMo-1 filler was the best choice for making the dissimilar joint of P92 and Inconel 617.

Summary: An 80%Ar-10%CO2-10%He ternary gas mixture was used as the shielding gas for narrow-gap welding of thick Q690E high-strength steel plates. Complete and defect-free welded joints were achieved, and the microstructure and mechanical properties were investigated. Lower heat input resulted in better microstructure and mechanical properties of the welded joints.

Summary: Virtual reality technology can improve the efficiency of traditional welding systems by simulating welding processes and providing learners with experience to avoid errors. This study presents a VR-based system for simulating three welding processes, SMAW, MIG, and TIG, and successfully tests its functionality. Welding speed and distance from the welding torch to the plates are important process parameters that determine the weld size and formation.

Summary: The effects of hot isostatic pressing (HIP) parameters and powder size distribution (PSD) on the microstructure and properties of powder metallurgy (P/M) IN740H were investigated. Managing these parameters appropriately can significantly tailor the properties of the material. Applying a thermal presoak to the input powder prior to sintering in HIP can increase grain size and coarse grain fraction, resulting in improved creep resistance but decreased tensile strength. The impact of powder thermal presoak on microstructure and properties is greater than that of a coarser powder size distribution alone. Furthermore, significant grain growth and grain boundary migration were observed in P/M IN740H at temperatures above 1260 degrees C in HIP. Compared to cast and wrought counterparts, P/M HIP IN740H with finer grain size typically has better tensile response. However, its creep life at 700-800 degrees C is inferior to wrought materials due to cavity nucleation sites at grain boundaries, leading to lower creep ductility. The ability to adjust the microstructure for a balanced creep and tensile behavior makes P/M HIP IN740H suitable for high-temperature applications.

Summary: This study investigated the influence of grain size and sheet thickness on the creep-rupture behavior of INCONEL (R) alloy 740H (R). It was found that both creep strength and ductility were crucial for the overall creep performance of the sheets. Reductions in performance were observed when the grain size was fine or when the grain sizes approached the sheet thickness, leading to accelerated creep or loss of rupture ductility.
