Title: The Innovations of Robert J Weaver
Introduction
Robert J Weaver is a notable inventor based in Concord, OH (US). He has made significant contributions to the field of electric arc welding, holding a total of 9 patents. His work focuses on improving the efficiency and effectiveness of welding electrodes.
Latest Patents
One of his latest patents is for a cellulose coated stick electrode. This innovative design features a center alloy wire surrounded by an outer cellulose coating that includes powdered fluxing agents, alloy powder, cellulose powder, and a binder. The improvement involves forming the binder as a solution of sodium silicate, comprising 61-78 percent by weight of the binder. This binder constitutes 25-35% of the coating, producing at least about 4% by weight of water in the electrode. Additionally, the fluxing agent used is titanium dioxide, which makes up more than 12 percent of the coating.
Another significant patent by Weaver is for a stick electrode designed to deposit a high-strength weld metal bead on a workpiece. The yield strength of the weld metal ranges between 85 ksi and 125 ksi, regardless of the cooling rate. This electrode deposits weld metal containing 0.80-1.85% by weight manganese, 0.25-0.50% by weight molybdenum, 1.25-2.50% by weight nickel, and less than 0.07% by weight carbon. The ratios of carbon, manganese, and molybdenum are adjusted to achieve a carbon equivalent in the deposited weld metal ranging from 0.17 to 0.30, preferably less than 0.22.
