Description
Schweißstab zur Ausübung des Verfahrens zum Schweißen durch elektrisch und chemisch erzeugte Wärme Es ist bereits ein Verfahren bekannt, bei dem durch die Schweißhitze einerseits elektrisch mittels eines Lichtbogens zwischen einem Schweißstab und dem zu schweißenden Körper und andererseits gleichzeitig chemisch durch eine in der Schweißwärme exotherm unter Gasabgabe verlaufende Reaktibn der vom Schweißstab getragenen Zusatzstoffe (Umhüllung) erzeugt wird. Bei diesem bekannten Verfahren wird ein Schweißstab verwendet, dessen Umhüllung ein unter derartiger Gasabgabe reagierendes Gemisch enthält, daß .durch die gasförmigen Reaktionsprodukte die auf der Schweißstelle liegende Schlacke fortgeblasen wird.Welding rod for performing the welding process by electrical means and chemically generated heat There is already known a method in which by the welding heat on the one hand electrically by means of an arc between a Welding rod and the body to be welded and, on the other hand, chemically at the same time by a reaction which runs exothermically in the welding heat with the release of gas Additives (coating) carried by the welding rod are generated. With this well-known Method, a welding rod is used, the envelope of which is an under such Gas release reacting mixture contains that .by the gaseous reaction products the slag lying on the welding point is blown away.
Diese Blaswirkung wird bei dem bekannten Verfahren dadurch erreicht, daß man der Umhüllung des Schweißstabes, die aus ' einem exotherm reagierenden Gemisch besteht, Hydrate oder Carbonate oder ein Gemisch von zwei oder mehreren von diesen Stoffen im Ausmaße vgn 6 bis za°ja des Gewichts der Umhüllung beigibt. Dabei können die Hydrate und Carbonate dein exothermen Gemisch beigegeben werden oder dessen oxydierende Stoffe ganz oder teilweise ersetzen. Bei dem bekannten Schweißstab sind als Carbonate Mangan-. Calcium-, Magnesium-, Eisen-, Bariumcarbonate, als Hydrate Eisen-, Mangan-, Aluminium-, Calcium-, Magnesiumhydrate, ferner Asbest, Kaolin, Ton, Hydrosilikate verwendet. Die Umhüllung des bekannten Schweißstabes setzt sich beispielsweise azusammen aus: 5o°/, Aluminiumgemisch, i5°fa Siliciumgemisch, i5°jo.Mangangemisch mit .901, Carbonaten, 50/0 Hydraten und io°/o anderen Stoffen (Gewichtsteile). Das Ganze wird mit Hilfe von Wasserglas oder durch ein anderes Bindemittel zusammengehalten. .This blowing effect is achieved in the known method in that the envelope of the welding rod, which consists of 'an exothermic mixture, hydrates or carbonates or a mixture of two or more of these substances to the extent of 6 to about the weight of the Wrapping is included. The hydrates and carbonates can be added to the exothermic mixture or completely or partially replace its oxidizing substances. In the known welding rod, the carbonates are manganese. Calcium, magnesium, iron, barium carbonates, iron, manganese, aluminum, calcium and magnesium hydrates, as well as asbestos, kaolin, clay, hydrosilicates used as hydrates. The sheath of the known welding rod is composed, for example, of: 50% aluminum mixture, 15 ° fa silicon mixture, 15 ° 1% manganese mixture with 901, carbonates, 50/0 hydrates and 10% other substances (parts by weight). The whole thing is held together with the help of water glass or some other binding agent. .
Die Erfindung betrifft nun einen Schweißstab, welcher mit einem in der Schweißwärme exotherm reagierenden und mit Blaswirkung gasabgebenden Gemisch umhüllt ist, und besteht darin, daß die Umhüllung Stoffe enthält, welche--am Abschmelzende gasförmige Reaktionsprödukte im Ausmaße von a,7 bis 5,4°/o - des Gewichts der Umhüllung entwickeln.The invention now relates to a welding rod which is equipped with an in the welding heat exothermic reacting and with blowing effect gas-releasing mixture is enveloped, and consists in that the envelope contains substances, which - at the melting point, gaseous reaction products in the range of a.7 to 5.4% - Develop the weight of the envelope.
Die Erfahrung zeigt, daß die mit einem Schweißstab gemäß der Erfindung erhaltenen Schweißstellen größere Zerreißfähigkeit, Dehnbarkeit, Kerbfähigkeit und eine bemerkenswerte Porenfreiheit gegenüber den bisherigen Schweißungen besitzen.Experience shows that with a welding rod according to the invention obtained welds greater tensile strength, ductility, notchability and have a remarkable freedom from pores compared to previous welds.
