اقرأ أكثرHelium versus Argon???
Good morning to all. It was suggested to me a good while back that Helium (as a shielding gas for TiG / MiG) would work better than Argon when welding Aluminum at thicknesses greater than 1/4 inch. The explaination given to me was that the Helium gas will generate a better "heat-up" of the material once the arc is iniated.Web

اقرأ أكثرWhat are tracer gases and why is helium used in leak detectors?
The leak detector converts the helium partial pressure. into a leak rate which it displays. The "leak rate" is the gas flow of the tracer gas through the leak. The unit is "mbar*l/s" or "Pa*m³/s". Usually, the term "standard leak rate" is used, i.e., the tracer gas is flowing from atmospheric pressure into vacuum.Web
