specific Embodiment approach 1

[0037] Specific implementation mode 1: This implementation mode is a kind of welding method for thick skeleton T-shaped structure laser oscillation filling wire single-sided welding and double-sided forming, which is specifically carried out according to the following steps:

[0038] 1. Carry out mechanical processing on the end face of the skeleton to be welded and the area to be welded on the skin; the thickness of the end face of the skeleton to be welded is d 1 3 ~ 12mm;

[0039] 2. Use a fixture to make the end surface of the skeleton to be welded in step 1 horizontal, and then fix it;

[0040] 3. Adjust the laser gun, and control the laser beam irradiation area to be located in the central area of ​​the end face of the skeleton to be welded, and then move the laser welding head to perform point-by-point calibration;

[0041] 4. Taking the center of the end face of the skeleton to be welded as the benchmark, check and adjust the walking path of the laser moving device to...

specific Embodiment approach 2

[0044] Embodiment 2: This embodiment differs from Embodiment 1 in that: the end surface of the skeleton to be welded in step 1 is a straight line or a curved surface. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0045] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the thickness d of the end surface of the skeleton to be welded described in step one 1 and skin thickness d 2 The ratio of is the bone-to-skin ratio γ, that is where 0.2≤γ≤0.8. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a welding method for one-side welding and double-side forming of thick skeleton T-shaped structure laser oscillation filler wire, and the invention relates to the field of material processing engineering. The invention aims to solve the technical problems of poor stability and low efficiency in the existing T-shaped structure welding method, and difficulty in welding thick skeleton curve weld seams. Method: 1. Process the end face of the skeleton to be welded and the area to be welded on the skin; 2. Place the skeleton and fix it; 3. Adjust the laser gun and calibrate it; 4. Adjust the walking path; 5. Assemble the skin; Welding parameters, to perform welding. The invention adopts laser oscillating wire-filling welding to achieve the effect of synchronous forming of the back of the skin and both sides of the skeleton through the front welding of the skin. Only one welding can realize the synchronous forming of the fillet welds on both sides of the skeleton, and the welding efficiency is doubled. The purpose, and can ensure the consistency and stability of the forming process. The invention is used for the complicated curve weld seam welding of thick skeleton T-shaped structure composed of skin-skeleton.

Description

technical field [0001] The invention relates to the field of material processing engineering. Background technique [0002] The T-shaped structure formed by the close contact between the skin and the skeleton is a common typical structure in engineering. The optimized design of the skeleton structure can not only effectively reduce the weight of the component and realize the lightweight manufacturing of the component, but also significantly improve the structure in some application fields. The comprehensive service performance of the components makes the key components based on the skin-skeleton T-shaped structure widely used in key fields such as aircraft shells, ships, and energy equipment. The manufacture of skin-skeleton T-shaped structures by welding is still the mainstream technology for mass production of such components. For this reason, domestic and foreign scholars have conducted a lot of research work on the efficient and high-quality welding of skin-skeleton T-sh...
