Spring 2014
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...

During the past several decades, the relationship between microstructure and mechanical properties of high strength microalloyed steels has been extensively studied in an effort to improve the fracture toughness and strength of these types of steels, without appreciably increasing steel...

Spring 2017
Heat distribution measurements in Gas Metal Arc Welding (GMAW) were concurrently measured at the cathode and anode giving increased insight and prediction capabilities. A calorimeter and water cooled cathode were used to determine energy partitions in GMAW for various electrodes, currents,...

Finite Element Model of the Thermal Profile During Submerged Arc Welding with One and Two Electrodes
DownloadFall 2016
The submerged-arc welding (SAW) process is used extensively in the manufacturing of pipes. The heat flow introduced by the welding operation has a significant impact on the properties of both the weld metal and the heat affected zone (HAZ). The work presented in this thesis aims to develop a...

Fall 2011
A calorimeter for the deposition of metal during free-flight GMAW was developed for the purpose of measuring droplet heat content in Ni/WC tubular wires. By approximating the thermal gradients within the calorimeter to be second order polynomials the energy transferred to the calorimeter by the...

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...

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...

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...

Spring 2012
This work is focused on development of tungsten carbide-based materials as alternative anodes for direct utilization of methane in solid oxide fuel cells (SOFCs). Not only were the capabilities of the anodes highlighted, but the challenges were also stressed. First, the impact of porous support...
