Anything with a melting point can be removed with this method, this is a hollow metal tube is connected to an oxygen tank and get a battery. This is mainly used when stuck in metal axles of buses, eg shovels or cylinders. The head of the lanselectrode reaches a heat of 10 000 degrees Celsius.
TIG welding is a welding procedure in which an arc is drawn between a non-consumable electrode and the workpiece. The molten bath and the electrode are protected by an inert (neutral) gas or gas mixture. The TIG name is an abbreviation of the English Tungsten Inert Gas (tungsten = tungsten).
An electric arc is maintained between the tip of a coated welding electrode and the workpiece. If the consumable metal droplets from the electrode through the arc end up in the weld pool, they will be protected against the ambient atmosphere by gases released from the coating of the electrode.
