The diffusion of electronics in the latest generation vehicles provides a new challenge for management of battery energy requirements. We find ourselves choosing tools to ensure maximum efficiency and duration over time of the battery to guarantee each vehicle is fully operational.

Arc welding with coated electrodes is a manual process where the heat source consists of the electric arc. When the arc strikes between the coated electrode ( by means of an electrode holder clamp) and the piece to be welded (base material), it generates heat which causes rapid melting of both the base material and the electrode (weld material).

Continuous wire welding in a shielded atmosphere is often identified by the abbreviations M.I.G. (Metal Inert Gas) and M.A.G. (Metal Active Gas) or G.M.A.W. (Gas Metal Arc Welding). Continuous wire welding is a process in which the heat required to carry out the weld is supplied by an electric arc that is maintained between the piece to be welded and the wire electrode. T

Arc welding in an inert gas shield with a non-consumable tungsten electrode (T.I.G. – Tungsten Inert Gas or G.T.A.W. – Gas Tungsten Arc Welding) is a procedure in which the heat necessary to make the welding is supplied by an electric arc which is maintained between a non-consumable electrode and the workpiece.

The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle. The temperature of the plasma is in excess of 20 000°C and the velocity can approach the speed of sound.

Spot welding works by applying pressure and heat to the weld area using copper alloy electrodes. These electrodes transport an electrical current through the weld segments. As the material melts the parts are fused. At this point, the current is turned off and pressure from the electrodes is upheld.
