The invention relates to the field of welding technologies, in particular to a method of forming a gas stream that is produced during electrolysis water electrolysis water generator, through which gas-flame processing of materials. The method is implemented in a small-sized portable devices.

The known method of forming the gas flow in the electrolytic-water gene is to control the operating current operating voltage elementary sources of the gas mixture (EIGS), at the same time provide consistent flow of fluid in EIGS and carry out the summation of the gas flow, after which the total gas flow through the protective liquid bubbler served on the output with a subsequent summation, if necessary, with hydrocarbon vapors for deoxidation (prototype).

The known method has the technological capabilities, which are the simplicity of manufacturing AEGS that can be used in the manufacture of various classes of small medical devices with advanced technological capabilities.

Technological result of the proposed invention is empowering known way by introducing additional operations.

The specified process is achieved in the following way.

The way the flame treatment of materials, including the production of the gas mixture when applying the operating voltage and current at the elementary sources of the gas mixture, which is placed in the casing with the liquid form the control signal to control the operating current, while providing consistent flow of additional fluid into the elementary sources of the gas mixture, summarize the g is up with the hydrocarbon vapors for deoxidation, form a gas cushion above the elementary sources of the gas mixture, thus before applying voltage and current through the elementary sources of the gas mixture is passed current, less operating current to displace the resulting gas mixture of the liquids from the gas cushion in the amount autopedia, and then install the operating current.

While mixing the gas mixture with the hydrocarbons is carried out by blowing the gas mixture through a couple of hydrocarbons.

Vapors of hydrocarbons formed by forced evaporation.

This forced evaporation is carried out by heat from elementary sources of the gas mixture.

While mixing the gas mixture with the hydrocarbon vapors carried out in the presence of the operating current, otherwise block the entrance and the exit of vapors of hydrocarbons.

Vapors of hydrocarbons formed in the channel inside the liquid environment of the hydrocarbons through the formation of a gas cushion.

When this diversion of the total gas stream is carried out on the volume of generated gas cushion and before applying the protective liquid bubbler previously served in the volume where they accumulate the total gas flow to a certain tablenamepattern sources of the gas mixture.

While imposing autopolis fluid in groups of elementary sources of the gas mixture, while continuously carry out the tap of the gas mixture and the flow of additional fluid in the middle part of the elementary gas sources.

That you are carrying out a continuous supply and discharge of the heated liquid with a gas mixture with different levels of liquid in the elementary sources of the gas mixture by a common or separate channels.

This autopolis fluid is carried out on discrete electrically isolated volumes, which have consistently over the total gas cushion, the exhaust gas mixture is performed in discrete volumes with the subsequent formation of the total gas stream.

This consistent flow of fluid in the elementary sources of the gas mixture is performed outside of these sources and their relative offset.

While the elementary sources of the gas mixture formed as a combined open contours.

Within the combined open paths consistent flow of fluid is realized by means of breaks in all internal closed contours with their relative offset.

This elementary sources gazovzvesi mixture in groups of elementary sources of gas medium is formed with a vertical sequence of feed and withdrawal.

In volume automotive sequentially form a gas cushion.

This exercise dissipation groups of elementary sources of the gas mixture due to the formation of increased length of the output of the gas channel is forcibly cooled.

The addition of gas streams is carried out in a dielectric channels total cover volume automotive made discrete.

This protects against back-strike in a liquid medium bubbler by ensuring the free passage of the total gas stream by direct pressure in the bubbler.

The mixing with the hydrocarbon vapors is carried out by partial or full flow to the total gas flow in the channel with the hydrocarbon vapors with the subsequent output is joint with the remainder of the total gas flow at partial deletion.

While monitoring the liquid level and pressure by combining the magnetic field with the appropriate level of the liquid and subsequent electrical commit the modified level.

Thus between the gas cushion and the basic sources of the gas mixture to form electrically isolated channel the CSOs gas stream by pre-feed hydrocarbons with extra volume, and then cover the total gas flow, and then the hydrocarbons with extra volume.

At the same time carry out the flame extinction, the total gas flow through short clamping channel total gas flow, and then remove the control signal.

When this control signal in the initial position is formed in the zone of the minimum operating voltage, and when forming the total working gas flow control signal shift in the zone of increased operating currents.

In Fig.1-4 depicts a group EIGS, which is located in a sealed housing with a lid 1 and a U-shaped plate 2 and is made in the form of a plate pack 3.

It should be noted that after transporting device of the gas cushion 6 naru is to join EEGS and extremely high initial currents, that entails a number of negative consequences. This inconvenience is eliminated by preliminary adjustment of the gas cushion 6 by passing a small operating current through EIGS 3. Resulting in a small current allocates the gas mixture in EIGS 3 and he fills the volume of the gas cushion 6, displacing from her shunt fluid volume automotive 4. After this operation EIGS 3 ready to work with high currents, i.e., to work in production mode.

One end of nozzle is put onto sleeve, and the other one - working one - in process of welding is located between welded edges of membranes. Working end of nozzle has two faces meeting at the sharp angle. Lower face is parallel to basic surface, on which trolley rides, and upper one is arranged at the angle of α=2÷4° to it. On upper face at the distance S from each other there are four rows of hot air supply parallel to flow. In each row via distance H=(1.2-÷1.5)S there are four holes provided. At the lower face there are similar rows of openings arranged.

EFFECT: improved quality of welding.

SUBSTANCE: invention relates to railway transport, particularly, to reclaiming or hardening worn-out surfaces of rails without removing the track from its bed. Proposed method comprises grinding metal surface, heating the damaged section by gas torch to below the rail metal fusion point, applying self-fluxing powder alloy with thermal expansion factor lower than that of steel onto rail working surface and melting the coat applied. Said powder alloy is applied in, at least, two layers to recover rated sizes of damaged section. Note here that first layer is applied on moving gas burner along and across horizontal plane at invariable distance between gas torch edge and rail surface. Second and subsequent layers are applied with torch oscillating over the entire width of rail head and overlapping previously applied layer sections. Then, natural cooling and mechanical processing of recovered surface are performed.

EFFECT: higher quality of reclaimed surfaces.
