Abstract
A method for preheating the welding wire used for TIG welding in order to increase the speed and quality of welding features that the argon arc is used as the heat source, the output current controllable TIG power supply is electrically connected across the weld gun and the feeding mouth of welding wire, and the argon arc is triggered to preheat the welding wire.
Description
Technical field:
The present invention relates to improvement to traditional TIG welding heat silk mode of heating.
Background technology:
Among the tradition hot wire TIG welding, adopt the method heating welding wire of resistance heated more, that is: make welding wire as the part in the circuit, when wherein having electric current to flow through, the welding wire heat that has a resistance, so welding wire is preheated.This technology is applicable to the welding of materials such as carbon steel, stainless steel, and these resistivity of material are bigger, and effect is obvious, but it is difficult to be applied in the welding of high conductivity material such as copper, aluminium.At present, the material of copper, aluminium is widely applied in fields such as national defence, is applicable to that hot wire TIG welding's solder technology of these materials has significance to production undoubtedly.
Summary of the invention:
The present invention provides a kind of method of argon arc preheating wire welding in order to solve hot wire TIG welding's problem of high conductivity material, and it adopts the method for electric arc heated, the hot wire TIG welding who has realized high conductivity material such as copper, aluminium.The present invention is achieved in that adopting the electric arc of argon shield is heating source, and one of the TIG power supply that output current is controlled is terminated on the welding gun, and the other end is connected to wire-feed motor wire feeding mouth place, the electric arc heated of igniting betwixt welding wire.Hot wire TIG welding's method of the present invention is a kind of efficient welding method of developing on cold wire feed TIG weldering basis, welding wire carries out preheating with welding wire before entering the molten bath, reduced the energy of arc-melting welding wire, filling deposition efficiency and speed of welding have been improved, maintain simultaneously the high-quality welding of TIG weldering again, this technology is widely used in surface overlaying or big slab TIG welding.Adopt this heating means, can be by regulating output current, welding wire is preheating to scope between 100 ℃～800 ℃, and, since adopt be electric arc as thermal source, be not subjected to the influence of material property, can heat the material of the high conductivity that comprises copper, aluminium etc.It is heating source that the present invention adopts the electric arc of argon shield, and welding wire is heated, and employing electric arc is thermal source, has solved the problem that material (as: copper, aluminium) that the traditional resistor thermal source can't be high to conductance heats; Adopt argon shield, avoided being heated the oxidation of welding wire.According to different electric arc power outputs, available hot-wire temperature's scope is widened greatly than traditional heated filament.
Description of drawings:
Fig. 1 is the process chart of the specific embodiment two.
The specific embodiment:
The specific embodiment one: present embodiment is like this welding wire to be carried out preheating: adopting the electric arc of argon shield is heating source; one of the TIG power supply that output current is controlled is terminated on the welding gun; the other end is connected to wire-feed motor wire feeding mouth place, the electric arc heated of igniting betwixt welding wire.
The specific embodiment two: present embodiment will be elaborated to the welding wire pre-heating mean in conjunction with Fig. 1.Present embodiment adopts the electric arc of argon shield TIG as the heating thermal source; as shown in Figure 1, two TIG weldering welding guns are installed on bracing frame, figure backhand welding rifle is used for welding work pieces; middle welding gun forms argon arc heating wire TIG technology by the fenestella of opening on the wire feeding mouth electric arc heated welding wire that ignites.
Claims (1)
1, the method for argon arc preheating wire welding; it is characterized in that it is achieved in that adopting the electric arc of argon shield is heating source; one of the TIG power supply that output current is controlled is terminated on the welding gun, and the other end is connected to wire-feed motor wire feeding mouth place, the electric arc heated of igniting betwixt welding wire.
