Description
Technical field
The present invention relates to gas shielded welding machine, more particularly, it relates to the improvement of plenum system.
Background technology
Gas shielded arc welding field gas consumption is huge, Market competition.Gas metal-arc welding connects, gas
Including argon, helium, carbon dioxide, mixed gas.The gas shielded welding machine of prior art, uses gas
Amount is big, has certain pollution to environment, and consumes energy, and product cost is high.
For arranging the welding machine of choking system, under non-solder state, confining gas exports, and reaches to economize on
The purpose of gas.
And in the weld state, the gas shielded welding machine of prior art, all it is to ensure that high pressure, high flow rate gas
The mode of continued emissions, for welding operation.
Summary of the invention
For the gas shielded welding machine of prior art, the present invention improves the choking system of gas shielded welding, purport
Contributing in terms of energy-saving and emission-reduction, have easy to install, quick, safeguard simple, solar term effect is high
Feature.
In order to achieve the above object, the present invention provides a kind of gas shielded welding machine method of work, welds at welding gun
Time, gas supply uses batch (-type) supply；Or gas supplies for the mode giving uninterrupted alternate cycles.
Wherein, batch (-type) supplies, and refers to that gas supplies a period of time, a period of time of stopping.As supplied 30 milliseconds,
Stop the mode of 300 milliseconds, supply and stop for alternately.And service time and stop for the time by the work welded
Condition determines, needs to consider such as welding gun power, the pressure of air feed equipment, flow velocity, air supply opening size, and quilt
The welding requirements of weldment, and the wind speed of external environment condition, temperature welding surroundings change, such as car in summer
Interior aeration-cooling, wind speed strengthens, and affects welding quality, and room temperature height makes protective gas volume become
Changing and affect welding quality, welding base metal oxidated layer thickness size welding quality all has an impact and determines.Generally
For a kind of operating mode, can most preferably supply and stop to be determined by experiment for mode.
And the mode of flow velocity size checker circulation, refer to that gas supplies that a period of time is fast, a period of time is slow
Alternately, or gas supplies from slow to fast, more from fast to slow, the mode moved in circles realizes.Ibid
Literary composition content, supply mode is determined by the operating mode welded, and is generally directed to a kind of operating mode, can be determined by experiment
Most preferably supply and stop for mode.
Additionally, when welding gun stops welding, stop gas supply.
In order to reach the effect above, present invention also offers a kind of gas shielded welding machine being provided with choking system,
Welding gun is supporting is provided with duty sensor, for detecting the welding current under welding gun welded condition；Described
Sensor connects control unit, and described control unit connects the gas supply electromagnetic valve of protection gas supply arrangement.Wherein,
Described control unit, according to the detection signal of described sensor, determines that welding gun is in welded condition, Jin Ertong
Cross and control described electromagnetic valve, it is achieved batch (-type) supplies or supplies in the way of flow velocity size alternate cycles.
Under optimal way, Germany's Fei Situo MHJ series of high-frequency valve selected by described electromagnetic valve.
Additionally, the welding of above-mentioned welding gun, refer to that welding gun contacts workpiece, it is achieved the state of welding operation.Now weld
Produce welding current between rifle and workpiece, can be detected by duty sensor.
Additionally, duty sensor is in the case of being not detected by welding gun welding current；Control unit according to
Detection signal cut electromagnetic valve, stops gas supply.
The present invention uses the supply of batch (-type) gas or the mode of batch (-type) conversion gas delivery volume, more persistently reduces
Flow velocity mode can effectively ensure that welding quality, can also reach solar term effect simultaneously.
The present invention selects the supply of batch (-type) gas or the side of batch (-type) conversion gas delivery volume (flow or flow velocity)
Formula, on the premise of ensureing welding effect, reaches solar term effect, and then has protection environment, energy-saving and emission-reduction
Advantage；Present system working stability, splashes few, has certain blowing-resistant ability.Ensureing same weldering
In the case of connecing effect, the present invention can reduce air consumption and reach 40～60%.
