Abstract

A method for brazing an electrically conducting connecting piece, for example a cable shoe, of an electrically conducting material to a workpiece of electrically conducting material, by means of a temperature controlled brazing process in which the heat necessary for brazing is generated by striking an electric arc between a carbon electrode, and the electrically conducting connecting piece, where the voltage and current is electronically controlled by control electronics to achieve a temperature development to result in a martensite free brazing, and wherein the DC voltage applied is using the carbon electrode as the negative pole, and using the electrically conducting connecting piece as the positive pole, and 0 wherein the carbon electrode is having a tapering, bevelled, or pointy end at the end facing the electric arc.

Abstract

A method for controlling a brazing process, including the steps of applying a welding current through an electrode (52) pressed to a metal surface (83) of a workpiece to form a welding arc. Further steps are continuously measuring the welding current and the welding time, continuously determining supplied energy on the basis of the welding current and the welding time, digitally switching current supplied from batteries of a DC source (10) and to maintain a substantially constant welding current, interrupting the supply of welding current when a predetermined amount of energy has been supplied and supplying heat to batteries when a temperature of the batteries is below a predetermined value. The apparatus comprises a control module (31) with a central unit (26)and a power control unit (28) wherein the central unit (26) and the control unit (28) are operatively connected for continuously measuring the welding current, a switched circuit module (12) producing a substantially constant welding current of a predetermined value and a first temperature transducer (36) provided in the vicinity of batteries included in the DC source (10). A heat transfer means (34; 70) is activated when the temperature of the batteries is below a predetermined value.
