Description
Technical field
The utility model relates to a kind of argon arc welding control device, especially for a kind of argon tungsten-arc welding control device that improves the argon gas utilization rate.
Background technology
In engineering constructions such as chemical industry, petrochemical industry, electric power, the argon Electricity Federation welder skill that capping is filled in the full GTAW technology (hereinafter to be referred as TIG) of industrial pipeline or TIG bottoming, manual electric arc welding (hereinafter to be referred as SMAW) obtains using very widely.Compare the full SMAW weldering of pipeline, TIG welder's skill has easy operating, weld shielding is effective, and weld structure is fine and close, and appearance of weld is attractive in appearance, no welding slag, flaw detection qualification rate advantages of higher.But it is higher that SMAW weldering production cost is compared in TIG weldering, and main cause is that the TIG weldering used highly purified argon gas as protective gas, and argon gas costs an arm and a leg, consumption is big.
Tig arc welding machine has argon gas and controls function automatically, and operation principle is following:
In Fig. 1, argon bottle links to each other with tig arc welding machine argon gas air inlet with tunger tube through pressure-reducing valve, argon flow amount meter, through a tunger tube tig arc welding machine argon gas gas outlet is linked to each other with the TIG welding gun again.During work, the welder presses the control button on the welding gun, starts the electromagnetic gas valve work in the tig arc welding machine, and argon gas gets into welding gun through electromagnetic gas valve.Welding is pressed (or unclamping) control button after finishing again, and electromagnetic gas valve ends, and does not have argon gas to flow out in the TIG welding gun, and argon gas uses and controlled reliably like this, and the argon gas utilization rate is high.
But special-purpose tig arc welding machine argon gas control has its limitation and deficiency.There are a large amount of alloy steel material welding in the engineering construction; Alloy steel material TIG needs the butt welded seam back side to carry out argon-filled protection during welding; But special-purpose tig arc welding machine has only single channel argon gas control function; Promptly can only control by the Butt welding gun argon gas, the butt welded seam back side is carried out argon-filled protection and then can't be controlled with argon gas; Tig arc welding machine argon gas control function is located in the tig arc welding machine in addition, and the TIG welding gun has three pipelines to link to each other with welding machine, and the one, electrode holder line, the 2nd, tunger tube, the 3rd, control cable.Receive the welding torch cable length restriction, tig arc welding machine is suitable for the welding of weldment from the position of welding machine close together, and the general job radius is no more than 10m.Characteristics such as but the engineering construction pipeline welding has at a distance, the high-altitude is many, and setting disperses, flowability is big, weld job is few on the contrary near welding machine.It is heavier to add welding machine weight, is not easy to random carrying, and welding machine is generally concentrated in welding machine case or welding machine builder's temporary shed and is provided with.But like this, remote during with high-altitude TIG welding procedure, must draw a very long tunger tube from tig arc welding machine and lead to the TIG welding gun with welding control cable.Because the argon gas long flow path has the following disadvantages:
A, argon shield lag behind, and argon gas has certain waste.This is because after pressing control button, high frequency starting the arc function operation, and the welding arc that ignites, though magnetic valve is also worked simultaneously in the welding controller, argon gas arrives welding gun needs certain hour, causes argon shield to lag behind.Starting the arc place is prone to produce defectives such as pore because argon shield is bad.In order to overcome the argon shield delay problem, when operating, the welder exits a period of time in advance, treat that purity of argon reaches back reignition of arc welding.And such waste that has caused many argon gas.
B, argon bottle are placed near the welding machine, and be far away from the welding position, and argon flow amount is regulated very inconvenient.
C, tunger tube are long, the tunger tube cracky, and the gas leakage of damaged back impacts welding quality, and causes the waste of argon gas.
D, tunger tube and control line are very long, have increased the weight of welding gun and welding cable, use and reclaim inconvenience, and have increased the fault rate of welding machine and control system.

Be implemented in the argon tungsten-arc welding operation through above-mentioned steps and improve the argon gas utilization rate, and realize in the operation two-sided protection workpiece.
GTAW is adopted in the welding of metallic conduit and equipment in a large number in the engineering construction, and GTAW needs in the Butt welding gun in the argon gas and the steel alloy back side argon-filled protection device argon gas to control, and prevents the argon gas waste.But existing tig arc welding machine does not have argon gas control function in the argon-filled protection device of the back side, and at tig arc welding machine apart from the welding position far the time, because of gas circuit is very long can't Butt welding gun in argon gas control or to control effect relatively poor.
A kind of argon tungsten-arc welding control device that the utility model provides through the argon gas control device that is provided with, makes operating personnel overcome because of operating point is bigger apart from the argon gas waste that welding machine far causes the technical problem that the argon gas utilization rate is low.This is because the volume of argon gas control device is little, in light weight, carries very conveniently, and the argon gas control device both can be placed near the welding machine, also can be placed on as required near the welding position, when work high above the ground, even just was placed on or hangs over the weld bond next door.Argon bottle is followed welding argon gas control device and is moved, and can also control with argon gas alloy steel backing face argon-filled protection in addition, has improved GTAW argon gas utilization rate greatly, has reduced welding cost.Compare tig arc welding machine, shortened gas circuit and control line length greatly, the welding position does not receive and the influence of welding machine position apart from distance, height.
Because the argon gas control device has two-way argon gas control function, both can control the welding gun argon gas separately, can control welding gun simultaneously again and workpiece reverse side argon-filled protection is used argon gas.
The input of argon gas control device is communicated with argon bottle through one or two argon gas pipelines, and output then passes through one or two argon gas pipelines and is communicated with welding gun and back side argon-filled protection device; Welding argon gas control is connected with control button on the welding gun through the control cable.Operating personnel realize the control to the welding argon gas through the control button on the welding gun.
