另一方麵，該辦法和凝結切割相比可能切口質量更差。實踐上它會生成更寬的割縫、明顯的粗糙度
、增加的熱影響區和更差的邊緣質量。激光火焰切割在加工精細模型和尖角時是不好的（有燒掉尖角的風險）。能neng夠gou運yun用yong脈mai衝chong形xing式shi的de激ji光guang來lai限xian製zhi熱re影ying響xiang，激ji光guang的de功gong率lv決jue議yi切qie割ge速su度du。在zai激ji光guang功gong率lv一yi定ding的de狀zhuang況kuang下xia

激光氣化切割

在激光氣化切割過程中
，資料在割縫處發作氣化，此狀況下需求十分高的激光功率。

，並且取決於資料、切割深度和光束焦點位置。在板材厚度一定的狀況下，假定有足夠的激光功率，最大切割速度遭到氣體射流速度的限製。
