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

The electric arc bypass is from the heated filament gas protective welding gun
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.
