| Resumen: | This part of ISO 21904 defines a laboratory method for measuring the welding fume capture efficiency of on-torch extraction systems. The methodology issuitable for use with all continuous wire welding processes, all material types and all weldingparameters.The method can be used to evaluate the effects of variables such as extraction flow rate, extract nozzleposition, shielding gas flow rate, welding geometry, welding torch angle, fume emission rate etc. on capture efficiency but can also be used, with specific test conditions, to determine capture efficiency. |
