SMALL ALLOY WELDING EQUIPMENT

Abstract

Welding is the most common process to join two types of metal. Capacitive welding is used in small alloys, jewelry and temperature sensors. A good quality welding is composed by a homogeneous distribution and uniformity of the material at welding point and a mass conservation, keeping the metal crystalline proprieties. Capacitive welding consists in submitting a metal to an electric arc, storing energy in capacitors, when released will melt alloy and creates a union. In an inertial chamber the atmosphere is controlled and Argon is injected by a solenoid valve, responsible to control Argon from a cylinder. Argon is a shielding gas responsible for the non-inclusion of external elements in the weld. This study develops equipment able to make capacitive welding using the principles mass and energy conservation in alloys and gauges pre-established, of different types of metals in an inertial environment, with the objective of create a good quality and efficient weld with low cost equipment with easy manipulation
