Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0027] see Figure 1 to Figure 3 , the embodiment of the present invention includes:
[0028] A laser welding device is composed of a welding head 1, a protective mirror 2, an inclined plane focusing mirror 3, an inclined plane reflecting mirror 4, a CCD camera 5, an anti-collision protection device 6, an air curtain device 7, and a protective drag cover mechanism 8. CO 2 The laser beam propagates through the air, irradiates the center of the protective mirror 2 vertically through the light entrance on the welding head 1, then passes through the inclined plane reflector 4, and then shines on the inclined plane focusing mirror 3, and through the ...

The invention discloses a laser welding device which comprises a welding head, a pair of protective glasses, a bevel focus lens, a bevel reflector, an anti-corrosive protecting device, an air curtaindevice and a protective pulling hood mechanism. A CO2 laser beam is irradiated perpendicularly to the center of the pair of protective glasses through an incident opening in the welding head, is irradiated to the bevel focus lens through the bevel reflector, and is focused and irradiated to the surface of a workpiece through the bevel focus lens; the anti-corrosive protecting device is mounted below the bevel focus lens; the air curtain device is arranged below the anti-corrosive protecting device; the protective pulling hood mechanism comprises an adjusting bracket, a cooling circulating water pipe, a first air inlet pipe, a second air inlet pipe and a pulling hood main body, the pulling hood main body is fixed to the lower end of the adjusting bracket, the upper end of the adjusting bracket is connected to the welding head, the cooling circulating water pipe is arranged on the pulling hood main body, the first air inlet pipe and the second air inlet pipe communicate to the pulling hood main body, and small holes are formed in the bottom surface of the pulling hood main body. In this way, the welding quality and the production efficiency can be improved.
Description
technical field [0001] The invention relates to the field of laser welding, in particular to a CO 2 Laser welding device and welding method. Background technique [0002] Laser welding is a high-efficiency and high-precision welding method that uses a high-energy-density laser beam as a heat source. As a new welding technology, laser welding has the advantages of fast welding speed, high production efficiency, high welding surface quality, and large welding depth. Small heat-affected zone and other advantages. With the continuous development of laser technology and numerical control technology, laser welding has become an advanced processing method in the field of industrial plate welding. [0003] At present, when laser welding titanium alloy, it is difficult to weld because titanium alloy is extremely easy to oxidize; the welding is not firm, the welding efficiency is low, and the welding quality is poor, which greatly increases the material cost and labor cost.
