Specific embodiment
The gas shield device 1 for long size butt weld 6 welding of the utility model is suitable for working as metal plate to be welded
Welding when material butt weld 6 is longer dimension, can effectively avoid bonding wire and is oxidized.With it is in the prior art that weldment is complete
It is placed in gas shield environment and welds difference, be the single or double that gas shield device 1 is placed in weldment, with this, realize
The welding of stage continuity (i.e. in the case where weldment does not move, sectional welding, that is to say, that use segmented welding mode
Complete the welding of long size butt weld 6), it is finally completed the welding operation of entire weldment.
The gas shield device 1 is by the shell 2 of thermally conductive good metal material production, the air inlet pipe of input protective gas 9
21 and output protection gas 9 gas outlet 22 constitute.
Shell 2 has a hollow inner cavity, and the wire 3 filled with arrangement of gathering in the inner cavity, air inlet pipe 21 is set
Set on 2 one end faces of shell, gas outlet 22 be arranged in on 21 opposing end surface of air inlet pipe or adjacent side.
The lateral length of the shell 2 in 50-200mm, i.e., weld every time corresponding 6 length of weld seam 50-200mm (i.e.
One section above-mentioned).
The metal mesh 4 that can prevent the wire in inner cavity 3 from deviating from is sealed on gas outlet 22.
Protective gas 9 (such as inert gas) is entered in the inner cavity by air inlet pipe 21, under the blocking dispersion of wire 3,
It is sprayed with uniform air-flow by gas outlet 22, provides uniform inert gas shielding atmosphere for welding region.
Wherein, wire 3 is also made of the metal of good heat dissipation effect, and effect is that the thermal energy of protective gas 9 is passed through shell
Body 2 exports, to reduce the temperature of the protective gas 9 sprayed by gas outlet 22, thus, under the temperature of bonding wire is quick when promoting to weld
Drop to oxidizing temperature or less.Concentrated protection gas 9 washes away butt weld 6, forms the protective gas 9 of high-purity simultaneously at weld seam 6
