Detailed Description
In order to better understand the scheme of the application, the following detailed description is provided for the application with the accompanying drawings and the detailed description.
It should be understood that the terms "first," "second," "third," and the like, are used for limiting the components, are used for distinguishing the components, and have no special meaning if not stated otherwise, and therefore, should not be construed as limiting the scope of the present application. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
Referring to fig. 1, the hanger provided in this embodiment may include a base 11, a barrel 12, and a barrel flange 13, which are connected in sequence, where the base 11 is provided with a through hole along an axial direction of the barrel 12. Wherein the hanger is mainly used as a container to store a special product, the length of the hanger is about 1000mm, the diameter of the hanger is about 160mm, and the wall thickness of the butt joint is 4 mm. The cylinder flange 13 is made of special stainless steel and is machined and integrally formed, and the structure is complex. The barrel 12 is made of a stainless steel pipe with a hollowed shape, so that the overall weight is reduced, and a plurality of reinforcing ribs are uniformly distributed on the outer circumference of the barrel to ensure the overall strength. The base 11 is used for bearing the whole weight of the hanger, and large reinforcing rib plates are uniformly distributed around the bottom. The flange ring is sleeved outside the cylinder body 12 to play a role in strengthening and positioning, and smooth transition is needed for connection between the rib plate and the flange ring, so that guiding is facilitated. The upper end and the lower end of the cylinder body 12 are respectively connected with the cylinder flange 13 and the base 11, a laser welding mode is adopted, the butt joint surface needs to be polished to be smooth before welding, and good connection is guaranteed. The hanger needs to consider the influence of welding shrinkage (about 1.5mm) during welding, and welding allowance needs to be left before welding the two ends of the cylinder 12. The hanger is transversely placed during laser welding, so that the automatic positioning of the laser welding machine is facilitated. The hanger needs to use a tool to position the three sections concentrically before laser welding, and then spot welding is carried out around a circle along a joint.
It is understood that laser welding is an efficient precision welding method using a laser beam with high energy density as a heat source. Laser welding is one of the important aspects of the application of laser material processing techniques. The laser welding method is mainly used for welding thin-wall materials and low-speed welding, and the welding process belongs to a heat conduction type, namely, the surface of a workpiece is heated by laser radiation, surface heat is diffused inwards through heat conduction, and the workpiece is melted by controlling parameters such as the width, energy, peak power, repetition frequency and the like of laser pulse to form a specific molten pool. Due to the unique advantages, the welding method is successfully applied to the precise welding of micro and small parts. The laser welding belongs to fusion welding, and uses laser beams as energy sources to impact a weldment joint. The laser beam may be directed by planar optical elements (e.g., mirrors) and then projected onto the weld with reflective focusing elements or mirrors. In addition, the laser welding belongs to non-contact welding, the operation process does not need pressurization, but inert gas is used for preventing a molten pool from being oxidized, and filler metal is occasionally used.
