[0041] The laser self-fusion welding device 6 comprises a welding head facing the welding piece 5 and used for welding the gap between the two welding pieces 5.

[0042] Specifically, the laser self-fusion welding device 6 is exemplarily an existing laser self-fusion welding robot, the specific model of which is not limited in the present application, and the laser self-fusion welding robot can realize high-speed reciprocating movement.

Exemplarily, the laser can be of a solid laser, a gas laser, a liquid laser and a free electron laser type. Two welding mechanisms are used for controlling the welding angle of the two welding pieces 5. The two symmetrically arranged welding mechanisms can be slidingly arranged on the base 1, and can be adapted to welding pieces 5 of different sizes. Each welding structure comprises a supporting assembly 2, a bending assembly 3 and a clamp 4, the supporting assembly 2 is slidingly arranged on the base 1, the bending assembly 3 is rotatably arranged on the supporting assembly 2, and the clamp 4 is fixed on the bending assembly 3.

When the cylinder rises, the support plate 31 can be controlled to rotate 0° to 70° in the mounting groove 221, so that the welding piece 5 clamped by the clamp 4 can be controlled to rotate 0° to 70°, so that the laser self-fusion welding device 6 can reciprocate when welding, and gradually rotate the two welding pieces 5 by gradually rising the cylinder until the two welding pieces 5 are parallel, and the laser self-fusion welding device 6 welds the gap between the two welding pieces 5. When the cylinder rises, the support plate 31 can be controlled to rotate 0° to -70° in the mounting groove 221, so that the welding head of the laser self-fusion welding device 6 can be inserted below the two welding pieces 5, and the laser self-fusion welding device 6 can reciprocate when welding, and gradually rotate the two welding pieces 5 by gradually descending the cylinder until the two welding pieces 5 are parallel, and the laser self-fusion welding device 6 welds the gap between the two welding pieces 5.

[0054] Specifically, the clamp head 41 is in a U-shaped form, a rotating rod 421 is rotationally arranged at the top of the clamp head 41, the rotating rod 421 is a screw rod, one end of which is provided with a rotating head, and the other end of which penetrates through the side wall of the clamp head 41 and is connected with a clamp plate 422, the bottom of the clamp plate 422 can be provided with a non-slip pad, so that when the welding piece 5 is clamped, the non-slip pad can be tightly attached to the welding piece 5, and the clamping can be stable.

[0060] Specifically, the rolling shafts 9 can be controlled to move in an arc shape on the support plate (as shown by the directions of the two arrows in the figure), and the two rolling shafts 9 gradually move close to each other, so that the angle between the two welding pieces can be gradually reduced to make the two welding pieces parallel. That is, the two welding pieces are gradually pressed by the two rolling shafts to gradually reduce the angle between the two welding pieces.

[0061] In some embodiments, a preheater is arranged on the base, and a preheating end of the preheater faces the welding end of the welding piece.

[0063] In some embodiments, the welding piece can be subjected to narrow-gap laser self-fusion welding by using a filler wire and a filler powder to assist in the welding process. The material to be welded is suitable for materials that are easy to oxidize and easy to form pores.

[0064] The specific welding process in the application is as follows:

[0065] First, the two stainless steel plates are clamped on the corresponding clamps 4 respectively, and the positions are ensured to be accurate, then the clamping plates 422 are rotated to clamp and tighten the stainless steel plates by rotating the rotating rod 421, after the fixing is completed, the angle between the two stainless steel plates is adjusted by controlling the lifting amplitude of the lifting cylinder, and the angle is kept at 50°-70°, for example, taking the lifting of the lifting cylinder 33 as an example, the support plate 31 is gradually flattened when the lifting cylinder 33 is lifted, and the driving speed is controlled at 1° per second, the parameters of the laser self-fusion welding equipment 6 are adjusted before welding, and the laser self-fusion welding equipment 6 is controlled to reciprocate during welding. In the welding process, the laser beam of the laser self-fusion welding equipment 6 moves back and forth along the welding area on the stainless steel plate. It is ensured that the motion trajectory of the laser beam matches the shape of the required weld and maintains a constant moving speed.

[0066] The parameters of the laser self-fusion welding equipment 6 include: the welding power is controlled to be between 2500-3000W, the welding speed is 80-100mm / s, the defocusing amount is 0-1mm, the gas flow is 25-30L / min, and the laser oscillator mirror system is turned on to realize high-speed reciprocating swing of the laser.

[0067] Further, the lifting cylinder 33 can be controlled according to the welding angle of the stainless steel plate, and the application is not limited to 0° (i.e., the two welding pieces are parallel).

[0068] Based on the same inventive concept, as shown in Figure 9 The application also provides a narrow-gap self-fusion welding method, which comprises:

[0069] The two welding pieces 5 to be welded are respectively clamped on the symmetrically arranged clamps 4, and the rotation angle of the bending assembly 3 is controlled to drive the clamps 4 to rotate, so that the angle of the two welding pieces 5 is within a preset angle range;

[0070] The laser self-fusion welding device is controlled according to the preset welding parameters to weld the two welding pieces 5.

[0071] During the welding process, the bending assembly 3 is controlled to bend at a speed of 1° per second until the two welding pieces 5 are parallel and seamless.

[0072] Specifically, first, two stainless steel plates are respectively clamped on the corresponding clamps 4 to ensure accurate positioning, then the clamping plate 422 is clamped on the stainless steel plate by rotating the rotating rod 421, after fixing, the angle between the two stainless steel plates is adjusted by controlling the lifting amplitude of the cylinder, and the angle is kept at 50°-70°. For example, the lifting cylinder 33 is lifted, the support plate 31 is gradually flattened, and the driving speed is controlled at a speed of 1° per second. Before welding, the parameters of the laser self-fusion welding device 6 are adjusted, and the laser self-fusion welding device 6 is controlled to reciprocate during welding. During the welding process, the laser beam of the laser self-fusion welding device 6 moves back and forth along the welding area on the stainless steel plate. Ensure that the motion trajectory of the laser beam matches the required weld shape and maintains a constant moving speed.

[0073] The parameters of the laser self-fusion welding device 6 include: controlling the welding power to be between 2500 and 3000 W, the welding speed to be 80-100 mm / s, the defocusing amount to be 0-1 mm, and the gas flow to be 25-30 L / min, and simultaneously opening the laser oscillator mirror system to realize high-speed reciprocating swing of the laser. The above welding method can achieve high-speed and high-quality welding results.

[0074] In some embodiments, the preset angle range is 50° to 70°. The rotation angle of the bending assembly 3 can be controlled according to actual welding requirements, which is not limited in the embodiment. The rotation angle range of the welding piece in the application can be 70° to -70°; the angle during welding is kept at 50°-70°, which is optimal.

[0075] In some embodiments, the preset welding parameters include: a welding power of 2500W-3000W, a welding speed of 80mm / S-100mm / S, a defocusing amount of 0mm-1mm, and a gas flow of 25L / min-30L / min. By controlling the welding power of the laser self-fusion welding device to be 2500W-3000W, the welding speed to be 80mm / S-100mm / S, the defocusing amount to be 0mm-1mm, and the gas flow to be 25L / min-30L / min, the welding cost and the welding time can be saved, and the quality of the welded stainless steel plate is better.
