    Abstract: A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.

    Abstract translation: 系统通过利用利用激光源与诸如氩或氦的惰性气体而不是空气或氧气的激光源来防止激光切割工件的氧化，以产生形成切割成工件的图案的槽或切口。 该系统在激光切割时将氧气引入工件，以氧化在激光切割过程中产生的任何炉渣或渣滓。 氧气或氧气与其他气体的混合物冷却炉渣和工件，同时氧化炉渣，以在炉渣撞击管状构件的暴露表面之前完全燃烧或部分燃烧炉渣。
