Submerged ARC Welding Investigation of Tubular Electrodes Designed for Submerged ARC Welding Applications.

摘要

The purpose of this report is to describe the methods used to weld the test samples and to present the results of the physical and metallurgical tests performed in this research and development program. This report covers the investigation of the operating characteristics of tubular welding electrodes designed for Submerged Arc Welding applications. The effort of this program was directed toward comparing the relative merits of tubular submerged arc welding electrodes as opposed to solid submerged arc welding electrodes. The Submerged Arc Welding Process (SAW) using conventional electrodes (solid wire) enjoys a prominent niche, as a welding process, due to high filler wire deposition rates and excellent quality of the deposited weld metal. The submerged Arc Welding Process is limited to the flat position for butt welds and the horizontal position for fillet welds. These limitations have not detracted from the popularity of the process as a fabricating tool. The process is normally used with mechanized welding equipment; however, it can be used as a manual process.
