metal active gas and metal inert gas welding

The gas chamber forms an active gas volume.

Air may be used as the operative gas.

The discharge gap is filled with lasing gas.

The gas laser further includes a lasing gas disposed in said discharge region and an excitation means (114) for energizing the electrodes to excite the lasing gas.

Gas is supplied to and released from the active gas volume to adjust the quantity of gas in the active gas volume to compensate for load changes on the vehicle or on at least one said pair of laterally spaced wheels.

The chamber is filled with an active gas from a generator (18) that deactivates or degrades targeted bio-hazardous materials, and, after a pre-selected period of time, the gas is evacuated (52, 54) from the confined chamber (12).

The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to provide a desired spectral line.

According to the inventive method, a process gas containing an active gas is directed to the processing point, carbon dioxide, oxygen, hydrogen, nitrogen, or a mixture of said gases being particularly suitable as active gases.

At this time, heating is begun while supplying nitrogen gas, an inactive gas, into the reactor, and an active gas, NH3 gas, is [also] supplied.

The chamber contains a working gas which includes a noble buffer gas and an active gas chosen to produce a desired spectral line.

The neutralizing gas is of a type which will reduce the reactivity of the coating substance in the active gas.

The active gas of the gas mixture is ammonia, hydrazine or a mixture of ammonia and hydrazine, the active gas content in the treating mixture ranging between 50 and 2000 ppm by volume.

The icemaking machine further includes a source of antimicrobially active gas and an air circulation system that causes the antimicrobially active gas to circulate through the bulkhead space.
