Description

Gegenstand der Erfindung ist ein Verfahren zum Schmelzschweißen oder Brennschneiden. Es ist bereits bekannt, zum Schweißen oder Schneiden Preßgas, d. h. Leuchtgas bis zu einem Druck von 200 mm Wassersäule, zu verwenden. Auch ist schon zu dem gleichen Zweck die Verwendung eines Gemisches von Leuchtgas und Azetylen unter erhöhtem Druck vorgeschlagen worden.The invention relates to a method for fusion welding or flame cutting. It is already known to use compressed gas for welding or cutting, i.e. H. Coal gas up to one Pressure of 200 mm water column, to be used. That is also for the same purpose Proposed use of a mixture of luminous gas and acetylene under increased pressure been.

Es wurde nun gefunden, daß bei Anwendung dieser Brenngase unter Druck besonders günstige Ergebnisse erzielt werden, wenn die Ver-It has now been found that using these fuel gases under pressure is particularly favorable Results are achieved when the

Patentanspruch :
Verfahren zum Schmelzschweißen und zum Brennschneiden mit verdichtetem Leuchtgas oder einem Gemisch von Leuchtgas und brennung mit einer möglichst geringen Sauerstoffmenge vorgenommen wird. Demgemäß wird nach der Erfindung Leuchtgas oder bei größerer, z. B. 6 mm übersteigender Stärke des Werkstücks ein Gemisch von Leuchtgas und Azetylen dem Brenner unter einem Druck von über 0,2 Atm., vorzugsweise unter einem Druck von 0,3 bis 0,45 Atm., der Sauerstoff dagegen mit 0,1 bis 0,3 Atm. zugeführt. Als vorteilhaft haben sich folgende Düsen- und Druckverhältnisse ergeben:Claim:
Process for fusion welding and flame cutting with compressed luminous gas or a mixture of luminous gas and combustion is carried out with the lowest possible amount of oxygen. Accordingly, according to the invention, luminous gas or larger, z. B. 6 mm thickness of the workpiece exceeding a mixture of luminous gas and acetylene the burner under a pressure of over 0.2 atm., Preferably under a pressure of 0.3 to 0.45 atm., The oxygen, however, 0.1 to 0.3 atm. fed. The following nozzle and pressure ratios have proven to be advantageous: Azetylen, dadurch gekennzeichnet, daß dem Brenner diese Gase unter einem Druck von über 0,2 bis 0,45 Atm. und der Sauerstoff unter 0,1 bis 0,3 Atm. zugeführt werden.Acetylene, characterized in that the burner these gases under a pressure of above 0.2 to 0.45 atm. and the oxygen below 0.1 to 0.3 atm. are fed.
