Desirable Combinations Of Electrode And Flux For Submerged Arc Welding Of Low Carbon Steel, James A. Husmann

Graduate Research Papers

The major purpose of this study was to provide information about desirable combinations of welding electrode and appropriate fluxes for submerged arc welding of low carbon steel. Other purposes were to:

1. Test a variety of combinations of available submerged arc welding electrodes and fluxes in welding low carbon steel.

a. Prepare specimens for tensile tests.

b. Conduct tensile tests.

c. Calculate tensile strength, yield point, break point, percent of elongation, and percent reduction of area.

2. Determine the most desirable combinations of electrode and flux for companies presently using or planning to use submerged arc welding for low carbon …

A Method For Improving The Accuracy In Phase Change Heat Transfer Data Through Increased Precision In Thermophysical Property Determinations, John Philip Drummond

Mechanical & Aerospace Engineering Theses & Dissertations

Wind tunnel model materials typically have thermophysical properties that vary with both position and temperature. A numerical study using a finite difference representation of the heat conduction equation has been performed on several of these model materials to determine their thermal response under a specified heat loading. This study has confirmed the feasibility of using an effective thermophysical property to account for the existence of variable thermal properties when a model undergoes aero­ dynamic heating. The effective property, when used in the reduction of phase-change heat transfer data, forced agreement of the actual transient behavior of a model with the …

Photo Chemical Milling, Terry R. Smith

Graduate Research Papers

This study is concerned with the techniques used in the production of metal parts by the use of photofabrication. Included will be a research of the historical background of the industry, and the production processes used by the photofabrication industry that apply to this project. Information will include careers, education, current status of the industry, as well as methods for implementing the processes into the industrial arts curriculum.
