Abstract

Process characterised in that it comprises: degreasing the pieces to be welded, heating them for 10 seconds until they reach 80 degree C and then applying to said pieces a liquid substance composed of sulphuric acid and water placing the ends of the pieces to be joined together applying a flux which is compatible with the materials of the pieces to be joined and with the flux to be used in welding applying heat to the pieces to be joined for 15 or 20 seconds until the temperature between 220 to 250 degree C is reached applying the flux in order to contact with the solder the joining point of the pieces to reapply heat for approximately 30 seconds until a temperature between 280 and 300 degree C is reached, applying it both to the pieces to be welded and to the solder to be applied, until the weld metal melts between the two pieces, becoming incorporated in the structure of both and cooling the solder (weld) for several seconds.
