Embodiment Construction

[0039] In general, for a welding machine using a generator, the operator sets the parameters of the method he wishes to implement according to the component he wants to make. Parameters selected by the operator typically include the material type and thickness of the parts to be welded, the type of shielding gas, the wire diameter and type, and the type of metal transfer mode. The generator sets the arc voltage as well as the current type and waveform according to the wire feed speed. The specific welding current depends on the wire feed speed.

[0040] The metal transfer pattern is determined by the welding energy, which is determined by the arc voltage and current. This energy determines the shape of the wire tip as it melts due to the flow of electrical current and the manner in which the constituent metals of the molten wire are delivered to the weld puddle.

[0041] figure 1 Shown are the various types of metal transport patterns that may be encountered in arc welding ...

Abstract

A device for arc welding with fusible wire comprising means (1) for setting the wire speed (Vf) and means (2) for selecting a metal transfer rate type, the means (1) for setting the wire speed (Vf) being manoeuvrable by the hands or fingers of an operator. According to the invention, the means (2) for selecting a metal transfer rate type cooperate with the means (1) for setting the wire speed (Vf) in such a way as to allow the operator to set the wire speed (Vf) by manoeuvring said means (1) for setting the wire speed (Vf) and to automatically select, on the basis of said wire speed (Vf) setting, a metal transfer rate type.

Description

technical field [0001] The present invention relates to an apparatus for arc welding using a fusible metal welding wire which allows the operator to set the wire feed speed and automatically selects the metal delivery mode according to the wire feed speed setting Type of (way, régime). The invention also relates to a method for welding at least one metal part, the performance of which is improved and the implementation of the method made easier by means of the device according to the invention. Background technique [0002] The method for arc welding using a fusible metal wire in a gas stream (also known as metal inert gas (MIG) or metal active gas (MAG) welding) relies on the use of a fusible metal wire as a fusible electrode. The use of an arc initiated (established, établi) between the tip and the metal parts to be welded. The heat of the arc allows both the constituent metals of the parts to be welded and the constituent metals of the fusible wire to melt, thereby prod...
