Silica gel column welding mixed gas carbon dioxide / argon
Silica gel column welding mixed gas carbon dioxide / argon Details:

The dust and toxic substances were measured in the working environment after the ion-charged partial purification device was installed in the CO2 gas shielded welding working environment of a metal structure factory. The report is as follows. 1 Contents and methods 80% of CO2 gas shielded welding Argon gas, 20% CO2 mixed gas, the welding wire is melted and welded under the specified voltage. The main hazard factors are dust, poison (manganese, iron, etc.), arc, etc. The dust is measured by the filter weight method; the free silica content The pyrophosphoric acid method is used; the potassium periodate colorimetric method is used for the determination of manganese and its compounds; the carbon monoxide meter is used for the determination of carbon monoxide; the naphthylamine diamine colorimetric method is used for the nitrogen oxides.
Application: HGT4984-2016 welding mixed gas carbon dioxide-oxygen argon, HGT3728-2004 welding mixed gas argon-carbon dioxide
