Torch welding report May 1st 2008 The danger of fumes from welding
have long been known. While
traditional capture hoods and
nozzles can work well, they require
an element of operator involvement
to ensure correct positioning of the
capture device.
For MIG welding it is possible to
integrate the capture nozzle into
the welding torch itself. This
removes responsibility from the
welder, as the point of extraction is
always in proximity to the weld.
Nederman and its partner
Abicor Binzel commissioned tests
at the Health & Safety Laboratory
to establish quantitative results of
capture efficiency via the welding
torch. A torch was connected to a
Nederman high vacuum system
and tests took into account
welding positions and parameters.
The report concluded that the
extraction of fumes via the torch
can offer high capture efficiencies
and, with the correct welding
parameters in place, there was no
disturbance of shielding gas and
no detriment to the integrity of the
weld. Free copies are available. More articles from Nederman Limited: |
