Minimising Exposure to Welding Fume - TWI

Workplace exposure limits (WELs) for the constituents of welding fume are provided in HSE Publication EH40.Generally,these limits are for exposure averaged over 8 hours,although for some components the average time is 15 minutes.In the UK there is no WEL for total welding fume,so exposure to each constituent needs to be considered.Minimising Exposure to Welding Fume - TWIWorkplace exposure limits (WELs) for the constituents of welding fume are provided in HSE Publication EH40.Generally,these limits are for exposure averaged over 8 hours,although for some components the average time is 15 minutes.In the UK there is no WEL for total welding fume,so exposure to each constituent needs to be considered.Influence of cooling treatment on corrosion behaviour of plate steel extension,and outstanding weldability.Two main properties of EH40 steels are currently investigated more than the others,and this relies on low-temperature toughness and high-efficiency welding process.Ma et al [15] demonstrated that EH40 thick steel plates have excellent toughness at
