On-torch capture
August 1st 2008 Welding fumes can damage
the nervous system and
respiratory tract and have
other adverse effects.
Traditional capture hoods
and nozzles work well, but
require an element of
operator involvement to
ensure correct positioning.
For MIG welding it has
been possible to integrate
the capture nozzle into the
welding torch itself and
advances have been made to
improve weight, efficiency
and manoeuvrability.
Nederman, with partner
Abicor Binzel commissioned
tests at the Health & Safety
Laboratory to check the
effectiveness of on-torch
systems. The report
concluded that extraction of
welding fumes via the torch
can offer very high capture
efficiencies and, with the
correct welding parameters
in place, there was no
disturbance of shielding gas
and so no detriment to the
integrity of the weld. More articles from Nederman Limited: |
