PATENT OFFICE DANIEL LAGRANGE AND FERDINAND DE PAPE, F UCCLE, BELGIUM, ASSIGNORS TO LA SOUDURE ELECTRIQUE ANTOGENE SOCIETE ANONYME, BRUSSELS, BELGIUM FUSIIBLE. ELECTRODE FOR ELECTRIC WELDING No Drawing. Application filed May 28, 1930,-Serial No. 456,802, and in France June 6, 1929.
its hardness up to about 300 and more. It is further known to add usual alloying metals for iron, copper, etc., in the coating with or without a reducing agent.
It has now been found that by adding bc Y ryllium in the coating of the metallic core of.
an electrode, an alloy containing beryllium is smoothly and evenly deposited by the welding operation, and, that furthermore the normal working voltage is reduced through a particularly favorable ionization of the arc interval. It has never been proposed to use beryllium in the coatings of electrodes,'-as an alloylingi metal for the metallic core, although in a general way it has been proposed to add alloying metals such as chromium or vanadium, etc., by including'these alloying metals, for instance, in the coating of an electrode, to obtain as weld metal the corresponding alloy without, however, the smooth welding and reduced voltage obtained when beryllium is used as in the invention.
According to the invention, electrodes for welding copper or aluminium or their alloys can be coated, for instance, by a suitable flux, forming a saline coating such as described in the U. S. patent application, No. 319,023, filed November 12, 1928, since matured into Patent No. 1,888,453,dated November 22,
1932, and divisional application, No. 482,916,
filedSeptember 18, 1930, since matured into- Patent No. 1,898,427, dated February 21, 1933, both in the name of Ferdinand do 0 Pape, and with powdered metallic beryllium considerably; 2 to 4% of beryllium increases or a beryllium compound incorporated in the coating with eventually a known reducing agent such as carbon. For instance, fluosilicate or beryllium can be added to said coating without a reducing agent, while carbon should be added to oxide of beryllium to ob tain a deposit free from metallic oxides. An electrode according to the invention and intended specially to obtain deposits of great hardness, for instance, in casehardening iron or steel (e; g., rails, gearing, etc), consists of a rod of soft iron combined with a coating containing beryllium or a beryllium compound with or without a reducing agent.
The metallic beryllium or beryllium compounds areusually added to the coating in proportions varying from 0.25% to 30% in weight of the dry coating. These are not,
however, fast limits to the scope of the invention.
When a relatively great percentage of beryllium is to be alloyed with the iron, copper, or aluminium, the core of'the electrode can be made outof a corresponding beryllium alloy, coated with a coating containing beryllium or a beryllium compound. The coating may, for instance, be obtained as follows; 80 grammes of active carbon are caused to absorb 100 cubic centimeters of beryllium chloride in a 99% solution. After more or less thorough drying, the product obtained is treated with concentrated ammonia. By this means beryllium hydrate is precipitated in the pores of the active carbon, the product is washed in water, to remove the greater part of the ammonium chloride formed, and then subjected to a slight calcination to expel the rest of the ammonium chloride. The calcined product is ground and added to the coating composed as mentioned, in proportions varying from 5 to in weight of the dry coating, to cover copper rod or a copper alloy rod.
In the same way, in the composition of salt coatings, for aluminium or aluminium alloy electrodes, according to this latter method of carrying out the invention, a chloride or other suitable compound of beryllium may be used, in suitable proporis reduced by the action of the electric welding arc.
We claim: 1. An electrode for electric arc Welding comprising a metallic core and a coating on the core, said electrodecontaining by weight of the core from 0.25% to 30% of beryllium. 2. An electrode for electric arc welding comprising a metallic core and a coating on the core, said electrode containing in the coating and by weight of the core from 0.25% to 30% of beryllium.
