The weld bead width and the penetration depth are major parameters that determine the mechanical strength of the weld joint. The analytic models, such as the Gaussian heat source model, may provide quite accurate estimations for the weld width and penetration; however, the model does not account...

Welding is defined as the joining of metals with extreme heat, producing fumes, which consist of harmful metals and ultrafine particulates that may lead to detrimental health effects. Currently, air sampling is the primary method to determine welding fume exposure, but is not always feasible....

Seven Ni-WC tubular wires utilized in this study were characterized by the nickel sheath area, powder composition, and overall initial carbide volume fraction of the wire prior to welding. The electrical resistivity of steel, stainless steel, and Ni-WC welding consumables were measured from...

Microstructural Characterization of Chromium Carbide Overlays and a Study of Alternative Welding Processes for Industrial Wear Applications
DownloadSpring 2014
Microstructural features of chromium carbide overlays (CCOs) were examined in this work. It was found that the microstructures can contain unmelted alloy powders. It was also shown that the structures of the primary M7C3 carbides are long hexagonal rods. Change in the microstructure from the top...

Tungsten carbide-based metal matrix composite coatings are deposited by PTAW (Plasma Transferred Arc Welding) on production critical components in oil sands mining. Homogeneous distribution of the reinforcement particles is desirable for optimal wear resistance in order to reduce unplanned...

Effects of Submerged Arc Weld (SAW) Parameters on Bead Geometry and Notch-Toughness for X70 and X80 Linepipe Steels
DownloadFall 2009
For the manufacture of higher strength pipelines to be feasible, a better understanding of the effects of welding on toughness is necessary. Bevel submerged arc welds were performed on X80 grade steel. The subsequent Charpy V-notch (CVN) test results indicated that the notch placement in the...

Ductile steel plate shear walls are an established lateral load resisting system. Past research indicates that cold-rolled infill panels less than 1 mm in thickness present one solution to an overstrength problem arising from selecting an infill panel thickness based on ease of welding and...

It is difficult to join high strength alloy steel which are produced by thermo mechanical controlled processing and get overmatched properties on the welds and heat affected zone (HAZ) when submerged arc welding (SAW) is used as joining process. Circumferential welds made in the mill to join...

Residual stresses can have a significant impact on the stability of structural members. In the case of I-section beam elements, such stresses can impact lateral--torsional buckling (LTB) capacity, particularly in the inelastic range. I-sections are typically fabricated by either rolling as a...
