Optimisation of GMAW via the alternating shielding gas technique
… of the weld joint, refined microstructure of the fusion zone, reduced heat input, and increased travel speeds of the welding torch. Yet, relatively little work has been carried out utilising this novel method. For instance, shielding gases employed during the arc welding procedures have been …

A Correlation of Microstructure With Hot-Ductility in the Heat-Affected Zone of Inconel 718.
… such stresses, cracking may occur in the fusion zone or in the weld heat-affected zone (HAZ). The objective of this study was to obtain a better understanding of hot cracking in the weld HAZ by making a correlation between the HAZ microstructure and the HAZ hot-ductility.

Three-dimensional transient thermo-elasto-plastic modeling of gas metal arc welding using the finite element method
… by comparing the numerically predicted size of fusion zone and heat-affected zone with experimental measurements. Effect of varying the shielding gas flow rate was also assessed and found to be negligible.

Fusion welding of diboride-carbide ceramic composites
… welding (PAW and PPAW) processes were used to fusion weld ZrB<sub>2</sub> containing 20 vol% ZrC. Varying welding parameters resulted in changes in weld pool shape and size, and the size of ZrB<sub>2</sub> grains within the fusion zone. For PAW processes that resulted in a keyhole fusion zone …

Control and qualification of titanium welds
… shear waves. The grain sizes at the weld fusion zone were found to be related to their ultrasonic attenuation by a mathematical relationship. The temperature effect in locating weld pool radii in titanium was found at temperatures up to 600 °C. The ultrasonic velocity decreased as the …

Effects of cold metal transfer welding on properties of ferritic stainless steel
… result of grain coarsening in the heat affected zone. Welding equipment manufacturers are constantly incorporating new technologies and capabilities into welding equipment, to make welding easier and create better welds, which then gives that manufacturer a competitive advantage. Cold Metal …

Thermomechanical behavior of advanced manufactured heat-resistant alloys and their weldments
… scatter and most failures occurred within the fusion zone. The fatigue performance was similar in welded AM and welded wrought, regardless of the presence of minor weld defects. The corrosion behavior of AM-to-wrought welded coupons for H282 and IN740H was examined in molten chloride salt …

Development of Low-Cost Polycrystalline Nickel-Base Superalloys for Gas Turbine Applications
… behaviour rationalised using Wagnerian diffusional analyses. So that further investigation of fundamental alloy behaviour could be performed, industrial quantities of three candidate alloys were produced. The initial characterisation of these materials is described, including a detailed …
