标准范围

ISO 14175:2008规定了熔焊和相关工艺中使用的气体和气体混合物的分类要求，包括但不限于:钨极电弧焊(工艺141)；气体保护金属电弧焊（工艺13）；等离子弧焊(工艺15)；等离子弧切割(工艺83)；激光焊接(工艺52)；激光切割(过程84)；电弧钎焊（工艺972）。工艺编号符合ISO 4063。ISO 14175:2008的目的是根据屏蔽、背衬、处理和辅助气体的化学性质和冶金行为对其进行分类和指定，作为用户正确选择的基础，并简化可能的鉴定程序。

ISO 14175:2008 specifies requirements for the classification of gases and gas mixtures used in fusion welding and allied processes including, but not limited to:

• tungsten arc welding (Process 141);
• gas-shielded metal arc welding (Process 13);
• plasma arc welding (Process 15);
• plasma arc cutting (Process 83);
• laser welding (Process 52);
• laser cutting (Process 84);
• arc braze welding (Process 972).

Process numbers are in accordance with ISO 4063.The purpose of ISO 14175:2008 is to classify and designate shielding, backing, process and assist gases in accordance with their chemical properties and metallurgical behaviour as the basis for correct selection by the user and to simplify the possible qualification procedures.
