Description
Technical field
The present invention relates to the gas shielded welding device in metal solder, specifically, relating to one can protect simultaneously
The gas shielded welding device of flat board positive and negative weld seam.
Background technology
In metal solder, aoxidize when high temperature for reducing weld metal, be usually taken and be passed through protective gas by weldering
The method that seam is opened with air exclusion.In welding process, creating the environment of protective gas in commissure, protection weld metal is not subject to
Air impact, prevents it oxidized, improves joint performance.Therefore, gas shield device generally exists in various welding equipments,
Different welding equipments be have developed targetedly to the gas shield device of correspondence.
Current prior art mainly solves pipe weld seam etc. and easily creates the problem of protection environment in pipe, and for flat board
Weld seam seldom has the device of correspondence to the problem solving weld seam oxidation.In flat board welds, Gansu Landtek petrochemical industry high new equipment share
Company limited devises coaxial shielding gas cover for Laser Welding, owing to Laser Welding has the solder joint of little area and less molten bath,
Therefore the mode of direct jet is used.And GMAW weldering and GTAW weldering are waited to the welding method only having front solder joint, only need
Molten bath, front to be done gas hood, its back side does not penetrates through, so when being formed without molten bath, the back side, typically need not carry out back of work
Protection.
Due to the piercing welding method including K-TIG, PAW, there is the advantage once welding double-faced forming, need same
Time butt welded seam positive and negative protect；Molten bath, front is relatively big simultaneously, and the back side also has longer molten bath, molten bath, the back side to be also required to fill
Code insurance protects, anti-oxidation and reduce surface tension thus stabilised bath.For back-protective, existing blow-through type guard method has
Of both defect, first the method protection face little, secondly blow-through gas is to the strong effect of weld pool surface, possible disturbance gas-liquid
Interface, deteriorates the stability in molten bath, the back side.
Summary of the invention
In order to solve slab construction tow sides weld seam is carried out the technical problem of gas shield, the invention provides one
Protect the weldment bearing table device of flat board positive and negative weld seam simultaneously, arrange at welding workpiece tow sides respectively and pass to protective gas

Detailed description of the invention
For present disclosure, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing detailed
It is described as follows:
As it is shown in figure 1, present embodiments provide a kind of weldment bearing table device protecting flat board positive and negative weld seam simultaneously, including
It is arranged on the downside of the workpiece of workpiece bottom and protects gas hood and be arranged at protection gas hood on the upside of the workpiece on workpiece top.Protect on the downside of workpiece
Tyre protecting shield mainly includes jig, air inlet 1, observation port 2, sealed groove the 3, first breather chamber 4, venthole 5.On the upside of workpiece
Protection gas hood mainly includes gas hood body, gas hood fixing hole the 6, second breather chamber 7, steam vent 8, weld seam groove 9.
As shown in Figure 2 to Figure 3, protecting gas hood to include a jig on the downside of workpiece, jig upper surface is provided with
Article one, along the sealed groove 3 that horizontal cross is through, jig is internally provided with the first breather chamber 4, and the first breather chamber 4 top opens
Mouth also communicates with the bottom of sealed groove 3.The observation port 2 being arranged within jig it is communicated with on the left of first breather chamber 4, right
Side is communicated with the venthole 5 being arranged within jig, observation port 2 and venthole 5 by the first breather chamber 4 in the horizontal direction
Pass to outside jig.Observation port 2 is opened above the air inlet 1 communicated therewith, and air inlet 1 is arranged in jig
Portion, and vertically passed to outside jig by observation port 2.The end of jig is provided with to be closed observation port 2
Transparent window, transparent window can select quartz glass to make.Workpiece is positioned over jig upper surface, and makes its reverse side weld seam
Being completely in the surface of the first breather chamber 4, the part that the first breather chamber 4 is not covered by workpiece then passes through the thin of different length
Plate is positioned in sealed groove 3 to carry out covering to it and closes.So, protective gas can from air inlet 1 through observation port 2,
Put down and be blown into the first breather chamber 4 and do not disturb weld pool stability, arrive the external world eventually through venthole 5, thus in reverse side weld seam week
Enclose creation gas shield environment, prevent weld seam from reacting when high temperature.
As shown in Figures 4 to 6, gas hood is protected to include the gas hood body of a rectangular structure, gas hood body on the upside of workpiece
Having cavity structure, this cavity structure is as the second breather chamber 7.The side of gas hood body 7 end face is provided with a circular gas
Cover fixing hole 6, gas hood body 7 is fixed on welding gun rifle head by this gas hood fixing hole 6, and gas hood fixing hole 6 has simultaneously and will weld
The protective gas of rifle pass-out imports the effect in gas hood body 7.Gas hood body bottom portion be provided with one through along horizontal cross
Weld seam groove 9, the fillet in normal shear fragmented packets of workpiece can be trapped among gas hood body interior by weld seam groove 9.The left surface of gas hood body sets
Being equipped with a semicircular steam vent 8, steam vent 8 is connected together with one end of weld seam groove 9, to facilitate fillet in normal shear to pass through,
Steam vent 8 has the effect discharging protection gas simultaneously.So, gas hood body can move along with the movement of welding gun rifle head, with
Time protective gas enter breather chamber by gas hood fixing hole 6, finally arrive the external world from steam vent 8, thus along with welding gun moves
Create gas shield environment around its positive weld seam welded, prevent weld seam from reacting when high temperature.
When using the weldment bearing table device of the present invention, according to size and the size of weld seam of workpiece, protect on the downside of workpiece
Placing suitable some thin plates in the sealed groove 3 of tyre protecting shield, be passed through protective gas from air inlet 1, protective gas leads to through first
Air chamber 4 is arrived the external world by venthole 5.Protecting gas hood to be fixed on welding gun on the upside of workpiece, protective gas is entered by gas hood fixing hole 6
Enter the second breather chamber 7 and eventually arrive at the external world.Gas hood lower wound in welded joints is protected on the upside of gas hood and workpiece by protecting on the downside of workpiece
Make the environment of protective gas, prevent weld seam from reacting when high temperature.
Although the preferred embodiments of the present invention being described above in conjunction with accompanying drawing, but the invention is not limited in
The detailed description of the invention stated, above-mentioned detailed description of the invention is only schematically, is not restrictive, this area common
Technical staff is under the enlightenment of the present invention, in the case of without departing from invention objective and scope of the claimed protection, it is also possible to
Make the concrete conversion of a lot of form, within these belong to protection scope of the present invention.
