Problems solved by technology

[0002] For the control of welding stress and deformation, many scholars have proposed many control methods and applied them in actual production, but these methods are still insufficient for the control of welding deformation of titanium alloy materials. Therefore, most methods are not suitable for aerospace titanium alloy thin plates. welding manufacturing
In order to get rid of the dependence on the preset temperature field for welding, a forced cooling method was invented, including the method of quenching with welding and the method of dynamic low stress without deformation, which can be applied to circular, circular and irregular welding commonly used in aviation complex structures. At the same time, water is sprayed synchronously during the welding process. Although it has the advantages of low cost and high cooling efficiency, water sprayed on the weld will pollute the molten pool, make the weld easily oxidized, and cause weld defects. Affect welding efficiency and quality

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1~5 As shown, the present invention includes a casing 1, and the casing 1 is a cylindrical structure with end caps sealed at both ends. A number of protective gas passages 6 are provided on the inner wall of the housing 1, and the protective gas passages 6 are arranged along the axis of the housing (the protective gas passages 6 can also be arranged in the housing 1 without contacting the side wall of the housing 1, and the two The end is fixed on the end cover at the end of the housing 1.), and three guide impellers 7 are respectively installed in each shielding gas channel 6 . The side wall of the housing 1 and the shielding gas passage 6 enclose a cooling liquid passage 8 . An air pipe 3 and a cooling liquid pipe 4 are arranged on the end cover; the air pipe 3 communicates with a plurality of protective gas passages through a plurality of br...

Abstract

The invention discloses a cold source device for welding. The cold source device for welding comprises a shell, the shell is of a cylindrical structure with end covers installed at the two ends in a sealed mode, a plurality of shielding gas channels are formed in the shell, and the shielding gas channels are arranged along the axis of the shell. A cooling liquid channel is defined by the side wall of the shell and the shielding gas channels. Gas pipes and cooling liquid pipes are arranged on the end covers. The gas pipes communicate with the multiple shielding gas channels through a plurality of branch gas pipes. The cooling liquid pipes communicate with the cooling liquid channel. The cold source device for welding is simple in structure and low in cost, shielding gas in the welding process can be rapidly cooled, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of gas shielded welding equipment, in particular to a cold source device for welding. Background technique [0002] For the control of welding stress and deformation, many scholars have proposed many control methods and applied them in actual production, but these methods are still insufficient for the control of welding deformation of titanium alloy materials. Therefore, most methods are not suitable for aerospace titanium alloy thin plates. Welded fabrication. In order to get rid of the dependence on the preset temperature field for welding, a forced cooling method was invented, including the method of quenching with welding and the method of dynamic low stress without deformation, which can be applied to circular, circular and irregular welding commonly used in aviation complex structures. At the same time, water is sprayed synchronously during the welding process. Although it has the advantages of low c...
