Abstract

Der Meisselhalter (1) aus warmfestem und rostträgem Stahl weist eine Bohrung (2) für die Aufnahme eines Meissels auf. Der Fuss (3) des Meisselhalters (1) wird mit dem Grund­ körper (5) eines Schrämkopfes durch Schweissen verbunden, wobei der Meisselhalter zumindest im Bereich des Fussteiles (3) einen durch Auftragsschweissen aufgetragenen Mantel (4) aus gut schweissbarem Stahl aufweist. Dieser Mantel (4) er­ streck sich höchstens über die Hälfte der Höhe des Meisselhal­ ters (1) und besteht aus ferritischem oder austenitischem Stahl einer Wandstärke von 0,5 bis 10 mm. Derjenige Teilbereich des Fusses (4) des Meisselhalters (1), auf welchem die Auftrags­ schweissung aufgetragen wird, ist im Bereich dieser Auftrags­ schweissung vor der Auftragsschweissung um die Stärke der Auftragsschweissung abgesetzt ausgebildet. The chisel holder (1) made of heat-resistant and rust-resistant Steel has a hole (2) for receiving a chisel on. The foot (3) of the chisel holder (1) is with the bottom body (5) of a cutting head connected by welding, the chisel holder at least in the area of the foot part (3) a jacket applied by build-up welding (4) made of easily weldable steel. This coat (4) he stretch at most over half the height of the chisel neck ters (1) and consists of ferritic or austenitic steel a wall thickness of 0.5 to 10 mm. That part of the Foot (4) of the chisel holder (1) on which the order welding is applied is within the scope of this order welding before the order welding to the strength of the Order welding trained separately.
