Filed:

Nov 16, 1992

Appl. No.:

7/977086

Inventors:

Dennis D. Crockett - Mentor OH
Ronald J. Gordish - Kirtland OH
Karl J. Kulikowski - Cleveland Hts. OH
Robert P. Munz - Jefferson OH

Assignee:

The Lincoln Electric Company - Cleveland OH

International Classification:

B23K 3522

US Classification:

219137WM

Abstract:

A cored electrode for gas shielded arc welding to deposit a weld metal bead, where the electrode has a core of fill material surrounded by a ferrous tube with the fill material having alloying agents and oxide fluxing ingredients including, by weight of fill material, 40-60% titanium dioxide, 0. 3-0. 5% boron oxide, and 1. 0-5. 0% aluminum powder, with the aluminum powder having a higher affinity for oxygen than the oxide fluxing ingredients and with the amount of aluminum powder selected to produce 0. 02-0. 08% titanium, less than 0. 002% boron and less than 0. 10% aluminum in the weld metal.

International Classification:

B23K 3522

US Classification:

21914624

Abstract:

A flux cored welding electrode for use in electric arc welding with a shielded gas, which electrode includes a tube of low carbon steel having on the inside thereof a titanium dioxide based flux with fluxing ingredients including aluminum oxide in the amount of 0. 1 to 0. 5% of the total weight of the electrode. The improvement of the invention wherein the titanium dioxide based flux with aluminum oxide free of magnesium or compounds of magnesium.
