There is no one size fits all solution to the problem of protection from dangerous welding fumes, rather a combination of actions and products will reduce the risks to a minimum for welders and others.
Well-designed and located extract ventilation to remove fumes is an essential element. Given that a very small welding fume particle can take potentially 2 days to reach the floor when released from a height of 1.5 metres, it’s clear these particles can remain suspended in the workplace air well after the welder has stopped welding or changed tasks.
It’s impossible to predict how long the impact of the pandemic will be felt and how effective global interventions have been. However, one thing is for sure, history shows the pandemic and the recession which follows will bring rapid, fundamental changes in the way our businesses operate. So, batten down the hatches while we ride this out - but equally importantly, keep an eye on the bigger picture and plan for change.
Heat input is one of the most important factors affecting the quality of a weld due to its formative effect on the Heat Affected Zone (HAZ) and weld metal properties, particularly mechanical toughness, and development of potential flaws.
