When He and Ar gases were used as the shielding gas, there were several porosities. porosities. It has been observed that, once the gas and the steel have been set, the penetration depth and the width of the melted zone are, in the majority of cases, virtually constant when the flow rate increases from 30 to 100 Nl/min. In our study, 95% of lesions treated with CO 2 laser were cleaned in a single session, while 46.2% of lesions in cryotherapy group were cleaned after 3 sessions during a 2-week interval. Anyway, I want to set an experiment :
Since the Author does not go through a good time, from the economic point of view, WHO WOULD, in His independence of judgment and decision-making, He could ( NOT OBLIGATORY ), send a modest Quantum, in euro, through POSTAGIRO or Bank transfer (or Postal transfer), crediting the Quantum (by you thought it right), on his ccp (postal account), payable to him, of which follows: CO2, He and N2 have been tested as covering gases with flows between 30+100 Nl/min. ( formable by hand - with fingers), with a lead core ( the so-called Serpents ). SPECIALI .
A mixture of gases — serving as the gain medium — comprised of carbon dioxide, nitrogen, hydrogen, an d helium. Bead-on-plate welding tests of 304 stainless steel plates were carried out at laser power 8.5 kW and 11 kW. The influences of the gas flow rate, the angle of nozzle and the gas jet position relative to the laser beam on the weld depth, the ratio of the weld depth to width and the The effects of side-blown operating parameters on the behavior of laser induced plasma and the weld seam geometry have been studied with the aid of high-speed CCD imaging in CO2 laser welding process of thin stainless steel plate.
When the argon flow rate is 10 1/min with the nozzle angle greater than 45 degrees, the plasma can be suppressed in the keyhole, and then a weld with great penetration and ratio of weld depth to width can be obtained. interaction between the laser beam and the laser induced plasma is very small because the wavelength of COIL is shorter than that of CO2 laser, so that the laser beam reaches on the workpiece without absorption by the plasma. On the other hand, the use of N2 gas made no porosity. 605 to 621, 1989Laser welding processes require nozzles with a " large " outlet in order both to avoid turbulent gas flow which can cause removal of the melt and to ensure an adequate protection of the melt against atmospheric oxidation.

The idea of adding Nitrogen (Argon, CO2 or any other INERT gas) is to eradicate the oxygen from the immediate environment, preventing the oxidation from taking place and allowing a homogenous weld.

The shield gas can play an important role in the process and can affect the resulting weld through influences on welding speed, microstructure, and shape.
