Abstract
The invention relates to an electric arc by-pass self-heating wire gas protection welding torch; a set of device for shunting and heating a filling wire through an electric arc bypass is additionally arranged on one side of an ordinary gas protection welding torch, so that the basic current of electric arc is ensured and the productivity and the welding quality are ensured on the one hand, the utilization rate of the electric arc energy is greatly improved, 50 percent to 100 percent of the productivity can be improved, and 50 percent to 100 percent of energy can be saved on the other hand.
Description
Technical field
The invention belongs to the accessory of a kind of efficient energy-saving of consumable electrode gas weldering
Background technology
Modern study shows that during electric arc direct current reversed polarity, the electric arc heat is superfluous on the negative pole workpiece, occurs overheated burning easily, is out of shape defectives such as big.A kind of DE-GMAW has abroad appearred; On original GMAW consumable electrode gas-arc power supply basis; Increase by one is shunted the minor arc electric current of absorption 31.9～45.5% to a tungsten argon arc welding gun and a cover electronic variable resistor device, makes the welding base current drop to 68.1～54.5% of minor arc electric current, still can keep the welding efficiency and the quality of arc stability; Can keep electric arc to be spray transfer, this is a kind of welding procedure of novelty.[notes]
But the energy of shunting generates heat on the electronics adjustable resistor and wasted in fact, and is very unfortunate.
Summary of the invention
The present invention has increased by an arbitrage to heat the device of filling silk with electric arc self by-pass shunt on gas protective welding gun; Fill the terminal middle part of silk and use heating filling silk to the arc divided electric current at electric arc; On the basis that guarantees welding quality, increase substantially productivity ratio and energy savings.
The advantage that the present invention and background technology comparison are had:
1, made full use of the energy of electric arc by-pass shunt, energy-conservation 50%～100%;
2, welding productivity can improve 50%～100%;
3, can make electric arc keep spray transfer, minimizing is splashed, and improves to be shaped;
4, avoid workpiece overheated, burn and be out of shape defectives such as big.
Figure of description
Figure, electric arc by-pass shunt are from the heated filament gas protective welding gun.
Among the figure: conducting rod assembly (1), ignition tip (2), heated filament joint (3), insulation wire leading pipe (4), heated filament cable composite-joint (5), insulation rifle body (6), protection gas cap (7), wire-feed motor (8), the source of welding current (9), workpiece (G)
The specific embodiment
The conducting rod assembly (1) of welding gun of the present invention is similar with general gas protective welding gun, it is characterized in that: a cover conducting rod assembly (1), ignition tip (2) and another set of heated filament joint (3), ignition tip (2) are combined on the insulation rifle body (6); Angle between two ignition tips is 45 °, and when welding wire stretched out ignition tip 16mm, welding wire was between left and right apart from being 2～4mm; Welding wire distance between the upper and lower is 3 ± 1mm; Outside is protection gas cap (2), heated filament joint (3) length 120～300mm, and length is decided by welding wire material and diameter; Insulated conduit (4) links to each other with heated filament cable composite-joint (5); Heated filament cable composite-joint (5) links to each other with workpiece (G), and the welding wire in the insulated conduit (4) relies on the electric current of arc divided and the resistance of self to heat, and has constituted the electric arc by-pass shunt thus from the heated filament gas protective welding gun; Wire-feed motor (8) respectively guide electric pole assembly (1) and heated filament cable composite-joint (5) wire feed is welded, during welding conducting rod assembly (1) preceding, heated filament ignition tip (2) after vertically advance.
