激光切割，顾名思义，是利用经聚焦的高功率密度激光束照射工件，使被照射的材料熔化、汽化、蚀或燃点，同时借助与光束同轴的气流吹除熔融物质，从而实现将工件割开。小编给大家介绍激光切割在加工碳钢时出现的问题解决方法
一般加工件出现毛刺，可能的原因包括：
(1)激光焦点位置发生偏移，做焦点位置测试，根据激光焦点的偏移量进行调整;
(2)激光的输出功率不够，需要检查激光发生器的工作是否正常，如果正常，则观察激光控制按钮的输出数值是否正确，若不正确加以调整;
(3)切割线速度太慢，需要在操作控制时线速度;
(4)切割气体纯度不够，需要提供高质量的切割工作气体;
(5)机床运行时间过长出现的不稳定X，此时需要关机重新启动。
出现激光未切割的原因：
(1)激光喷嘴的选择与家工板厚度不匹配，换喷嘴或家工板;
(2)激光切割线速度太快，需要操作控制线速度。
切割低碳钢时出现非正常火花
正常切割低碳钢时，火花束长、平，开叉较少。出现非正常的火花时影响家工件的切割断面的光滑度和家工质量。
此时在其他参数都正常的情况下，应考虑以下情况：
(1)激光头喷嘴损耗严重，应及时换喷嘴;
(2)在无新喷嘴换的情况下，应切割工作气体压力;
(3)若喷嘴与激光头连接处螺纹松动，此时应暂停切割，检查激光头连接状态，重新螺纹。
