Detail some recent developments made in welding equipment/technology

摘要

The importance of monitoring has been addressed through the introduction of advanced techniques, particularly continuous oxygen and dew point measurement. Weld purge oxygen monitors using rapid response, accurate instruments, introduced from 1996 satisfied the need for measurement as low as 50 ppm oxygen. Later developments led to instruments capable of meeting site applications whilst reading oxygen levels down to 10 ppm. Many of these products now incorporate software for downloading of data for quality control purposes, fault finding diagnosis, alarm features to warn of high oxygen levels, full colour touch screen control and IP65 rating.
