METHOD OF THERMOELECTRIC CONTROL OF BRAZED LINKING AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC G01R31/04 

FIELD: physics; measuring.

SUBSTANCE: invention concerns control equipment. Determine value of thermal EMF in brazing place, time of action by heat radiant on a braze zone, time of a solidification of solder and value of thermal EMF at the moment of the beginning of a solidification of solder with the subsequent evaluation by a method of a successive analysis of average values of the quantities spotted as a result of a series of experiments. Quality of the soldering is estimated on diversions of the quantities spotted as a result of a series of experiments, from confidential field. The device the signal thermal EMF amplifier contains, the block of decision-making joined to the registering block, differentiating block, the zero-body block, the block of a key of removal of information readout, the block of a logic unit of delivery of gating impulses of readout, the measuring block of stationary intervals continuances, the block of evaluation of average values.

EFFECT: operative and reliable estimate of brazed linking quality during all time of a work cycle.
