ELECTRODE FOR SURFACING Russian patent published in 1997 - IPC

FIELD: mechanical engineering; surfacing and repair welding of defects in railway spiders and other castings of high manganese steels. SUBSTANCE: electrode has rod made of low carbon or low alloyed manganese-containing steel, and sheathing. Sheathing contains, mass %: rutile concentrate 5-20; metal carbonate 4-10; silicate mineral 2-5; chromium 32.0-39.6; nickel 2.5-8.0; fluorite concentrate 5-15. Summary content of nickel in electrode is 1.6-5.0% and that of chromium - 20.5-32.0%. Sheathing includes also manganese in amount providing its summary content in electrode equal to 11-18%. Mass coefficient of sheathing is 120-160%. Electrode provides high welding and processing properties at high operating characteristics of surfaced parts at decrease in their cost. EFFECT: improved quality of repair. 6 cl, 1 tbl
