Abstract
1,124,523. Soldering; hard surfacing of tools; cutters and templates. METRO-CUTANIT Ltd. 28 Jan., 1966 [1 Feb., 1965], No. 3905/66. Headings B3A, B3B, B3L and B3R. [Also in Division B5] A steel strip having one or more hard metal plates forming a working or wearing part soldered thereto is provided with spaced tapered slots, transverse to the longitudinal direction of the strip, carrying truncated wedges of material having a lower coefficient of thermal expansion and a higher modulus of elasticity than the steel of the strip, the wedges being adjacent the plate or plates. Each plate has a length at least five times the mean of its width and thickness and the term hard metal includes carbides, borides, nitrides and silicides of metals of the fourth, fifth and sixth groups, e.g. tungsten, tantalum and titanium carbides, with one or more metals of the iron group, e.g. cobalt as a binder. In making a guide straight edge for use in centreless grinding, spaced slots 3, Fig. 1, are provided in the upper edge of a steel strip, the strip is brought to soldering temperature and truncated wedges 4 of hard metal, e.g. tungsten or molybdenum, are forced while at room temperature into the slots and finally the hard metal edge 2 is soldered with a copper or silver base solder to the upper edge. Medium or high frequency induction heating or burners may be used. The hard metal edge may be formed in two lengthwise parts. In making a planing cutter for wood working a hard metal edge 6, Fig. 6, is soldered at one side of a steel strip and slots 7 are provided at the other side carrying wedges 8 of tungsten. The wedges are inserted before or during soldering. Narrow slots 9 are provided between the slots 7 and the hard metal edge. In making a cutting chisel the hard metal cutting is soldered in a longitudinal slot and slots carrying wedges of hard metal are provided in both sides of the steel strip. The composite strip may form a stone working tool, e.g. for engraving or dressing and may be curved, e.g. a shaping cutting, scraping tool or template, e.g. for use in ceramic working.
