焊接.氧气火焰切割、激光束切割和等离子体切割的缺陷

[中文适用范围]： 本国际标准定义了收集和分组的金属材料中氧气、激光束和等离子切割中可能存在的缺陷的术语。 缺陷是指与指定形状和切割位置的不规则或偏差。 本国际标准仅包括直接源自火焰切割、激光束和等离子弧切割的缺陷；不考虑额外的外部应力或应变造成的任何不利影响。 这些缺陷的类型、形状和位置被分组在一起，但没有给出产生的条件和原因。 未给出有关上述缺陷的评估和后果的信息，因为这取决于具体的工作要求。 这些术语的选择是为了描述所提到的主要缺陷，但是，可能会同时发现两个或多个缺陷。 使用的分组系统不是质量评估。 [外文原描述]： This international Standard defines terms of the possible imperfections in oxyfuel gas, laser beam and plasma cuts in metallic materials which are collected and grouped. Imperfections are irregularities or deviations from the specified shape and location of cut. This international Standard only includes imperfections originating directly from oxyfuel gas, laser beam and plasma arc cutting; any adverse effects resulting from additional external stresses or strains are not considered. The type, shape and location of these imperfections are grouped together but conditions and causes of origin are not given. Information concerning the evaluation and consequences of the above mentioned imperfections is not given because this depends on the specific job requirements. The terms have been selected to characterize the principal imperfections mentioned, however, two or more may be found simultaneously. The grouping system used is not an evaluation of quality.
