Abstract

In a stick electrode for electric arc welding having a center alloy wire and an outer cellulose coating which coating includes powdered fluxing agents, alloy powder, cellulose powder and a binder. The improvement involves forming the binder as a solution of sodium silicate and 61-78 percent by weight of the binder. The binder comprises 25-35% of the coating to produce at least about 4% by weight of water in the electrode. Furthermore, the fluxing agent is titanium dioxide with a percentage greater than 12 percent of the coating.
