METHOD OF FORMING BACK STROKE PROTECTION IN ELECTROLYSIS-WATER GAS GENERATOR Russian patent published in 2005 - IPC

FIELD: welding techniques and procedures.

SUBSTANCE: method can be used in gas-plasma processing of materials. Method is based upon getting gas mixture when applying working voltage and current to elementary sources of gas mixture which are made in form pack of metal plates to be disposed in air-tight case with electrolyte and space for automatic grouting. Gas flows are summed into total flow which is applied to output through gas channel and operation space of bubbler with liquid. Operating volume of bubbler with liquid is disposed either at inner side of gas channel, each of which is made in form of cylinder with common air-tight dislocation or at outer side. Gas flow is applied into working space at its bottom side through one or several holes provided with elastic plate. During feeding gas flow inside working space of bubbler the hole or holes are not closed with elastic plate but at sharp increase of pressure inside working space of bubbler at back stroke the hole or holes are blocked with elastic plate to prevent squeezing liquid out of working space of bubbler through holes and gas channel into inner space of gas generator.

EFFECT: improved efficiency of operation of small-sized weld apparatus.
