Description

358281358281

Die Erfindung !betrifft eine Schweißelektrode, die so ausgebildet ist, daß sie die zu schweißenden Körper aufnehmen kann und besteht darin, daß die .zur Aufnahme dienende S öffnung oder Vertiefung mit einem entfernbaren Metallfutter versehen ist, das nach dem Ausbrennen oder bei sonstigen Beschädigungen herausgenommen und durch ein neues ersetzt werden kann. Das Futter besteht vornehmlich aus einem Metallstreifen, der an den Rändern der Vertiefung angebracht wird, da hier gewöhnlich die Elektroden ausbrennen.The invention relates to a welding electrode which is designed in such a way that it can absorb welding body and consists in the fact that the .to take up The opening or recess is provided with a removable metal lining, which is burned out or other damage can be removed and replaced with a new one. The feed consists mainly made of a metal strip attached to the edges of the recess as this is where the electrodes usually burn out.

Die Zeichnung veranschaulicht eine Ausführungsform der Erfindung, und zwar ist Abb. ι eine Draufsicht auf die untere Elektrode und Abb. 2 ein Querschnitt nach 2-2 der Abb. 1.
Da die beiden dargestellten ElektrodenThe drawing illustrates an embodiment of the invention, namely Fig. 1 is a plan view of the lower electrode and Fig. 2 is a cross section according to 2-2 of Fig. 1.
Because the two electrodes shown

ao genau gleich sind, so soll nur eine beschrieben werden. Die zu schweißenden Körper A, B sind im dargestellten Falle die Längshälften eines Zylinders, die in die Elektroden C und D eingelegt sind. Diese werden in geeigneter Weise gegeneinander bewegt, derart, daß die Ränder oder Kanten der Zylinderhälften A und B gegeneinander treffen, worauf der Strom zwecks Vereinigung der Hälften eingeschaltet wird.ao are exactly the same, only one should be described. The bodies A, B to be welded are in the illustrated case the longitudinal halves of a cylinder which are inserted into the electrodes C and D. These are moved towards one another in a suitable manner, in such a way that the edges or edges of the cylinder halves A and B meet one another, whereupon the current is switched on for the purpose of uniting the halves.

Es hat sich gezeigt, daß, wenn die Elektroden aus einer zusammenhängenden Metallmasse bestehen, der Schweißstrom ein Ausbrennen oder sonstige Verletzungen der Elektroden an den Winkeln oder Ecken zwischen ihren sich gegenüberstehenden geraden Oberflächen und den Vertiefungen oder Aussparungen bewirken, die die zu schweißenden Körper aufnehmen. Dies wird gemäß der Erfindung dadurch verhindert, daß man das Metall der Elektroden an diesen Stellen wegnimmt, so daß sich ein Absatz ergibt, auf dem man einen Metallstreifen E mittels Schrauben F entfernbar befestigt. Dieser Streifen bildet eine teilweise Ausfütterung der Vertiefung und ist der Form derselben angepaßt. Brennt irgend einer der Streifen E aus, oder wird er sonstwie beschädigt, so kann er leicht entfernt und durch einen neuen ersetzt werden.It has been found that when the electrodes consist of a coherent mass of metal, the welding current causes burnout or other damage to the electrodes at the angles or corners between their opposing straight surfaces and the recesses or recesses that receive the bodies to be welded. According to the invention, this is prevented by removing the metal of the electrodes at these points, so that a shoulder is produced on which a metal strip E is removably fastened by means of screws F. This strip forms a partial lining of the recess and is adapted to the shape of the same. If any of the strips E burns out or is damaged in any other way, it can easily be removed and replaced with a new one.
