裏面に強固に凝固するといった開門点かあ−た。As mentioned above, conventional Al material processing methods use oxygen gas for processing, so an aluminum oxide compound is generated by laser cutting, and this hardens into powder-like dross and solidifies on the back side of the material. That was the opening point.

を行うことができる。The laser cutting method of Al material in the present invention uses a mixed gas of argon gas and 5 to 50% oxygen gas to reduce the amount of oxidized compounds generated by laser cutting compared to conventional oxygen processing gas, and In addition, since it is assisted by a combustion reaction with oxygen, it is particularly suitable for laser cutting of thick aluminum plates, and can perform cutting with less adhesion of Paris-like dross.

吹きつけてレーザ切断を行う。Examples of the present invention will be described below. As shown in Figure 1, the laser beam (
1) is focused by a processed lens (2). At the same time, 5 to 50% argon gas is added to the processing head (2).
A processing gas consisting of a mixed gas of oxygen gas is injected and blown onto the Al material (6) of the workpiece through the opening of the nozzle (5) to perform laser cutting.
ここで、従来のように加工ガスに酸素ガスを使用すると

成され、パリ状のドロスが付着する。Here, if oxygen gas is used as a processing gas as in the conventional method, an oxidized compound is generated on the back surface of the Al material (6) during laser cutting, and Paris-like dross is attached.

レーザ切断では、どうしても酸素ガスによる燃焼反応に
よるが量の発生が必要となる。Therefore, argon gas is used to prevent the generation of oxidized compounds due to oxygen gas, but especially in laser cutting of thick plate A1 material, it is necessary to generate a large amount of argon gas by combustion reaction due to oxygen gas.

A processing gas consisting of a mixed gas of argon gas and 5 to 50% oxygen gas is optimal.

。However, if the amount of mixed oxygen gas is less than 5%, almost no oxidative exothermic effect can be expected, and on the other hand, if it is more than 50%, the oxidative exothermic effect becomes excessive and the roughness of the cut surface becomes significant. The optimal amount of gas is 5-50%.

=, it is possible to reduce the adhesion of dross from oxidized compounds compared to conventional oxygen processing gas, and by using the heat generated by the combustion reaction of the slightly mixed oxygen gas, it is possible to reduce the adhesion of dross on even quite thick plates. It is possible to laser cut a small amount of high quality Al material.
