BS EN ISO 17658:2015

This standard BS EN ISO 17658:2015 Welding. Imperfections in oxyfuel flame cuts, laser beam cuts and plasma cuts. Terminology is classified in these ICS categories:

• 25.160.10 Welding processes
• 01.040.25 Manufacturing engineering (Vocabularies)

This international Standard defines terms of the pos­ sible imperfections in oxyfuel gas, laser beam and plasma cuts in metallic materials which are collected and grouped. Imperfections are irregularities or devia­ tions from the specified shape and location of cut. This international Standard only includes imperfec­ tions 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 im­ perfections are grouped together but conditions and causes of origin are not given.

Information concerning the evaluation and conse­ quences of the above mentioned imperfections is not given because this depends on the specific job re­ quirements. The terms have been selected to charac­ terize the principal imperfections mentioned, however, two or more may be found simultaneously. The group­ ing system used is not an evaluation of quality.
