Problems solved by technology

However, this forming method has some limitations: (1) The cost of establishing an atmosphere chamber and maintaining the atmosphere concentration in the atmosphere chamber is high: (2) The size of the formed part is limited by the size of the atmosphere chamber, and it is impossible to form and clad large or super-large components; (3) Because the atmosphere chamber is difficult to move, this restricts the entire laser forming system from being able to go to the site where the parts are damaged for on-site repairs

Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] A local atmosphere protected metal or alloy laser cladding and forming method of the present invention is used in the cladding process, mainly used to protect materials that are easy to react with air, such as titanium, magnesium aluminum and their alloys, and the essence of the method is to use a local atmosphere chamber Laser forming of titanium or titanium alloys. The local atmosphere protection metal or alloy laser cladding and forming method is as follows: the metal or alloy powder beam is transported by the inert carrier gas and moves with the focused laser beam on the processing surface; at least one beam of inert shielding gas is formed on the periphery of t...

Abstract

The invention relates to a method for protecting metal or alloy in a local atmosphere in the laser cladding and forming processes. The method comprises the steps that a metal or alloy powder bunch is conveyed by inert carrier gas to move on the machining surface along with a focused laser beam; at least one layer of inert protective gas is formed on the periphery of the metal or alloy powder bunch; and the inert protective gas comprises first inert protective gas, and the first inert protective gas surrounds the periphery of the focused laser beam. According to the method, the inert protective gas is formed on the periphery of the focused laser beam so that the problems that in the forming process of parts, the size is limited, the cost is high, a cladding and forming system is difficult to move and the like can be solved. The invention provides the method for forming and repairing the on-site parts. Compared with the prior art, the method has the advantages of being convenient, rapid and economical.

Description

technical field [0001] The invention relates to a local atmosphere protection metal or alloy laser cladding and forming method. Background technique [0002] Laser cladding forming is a micro-metallurgical accumulation forming process based on the "discrete-accumulation" principle. It is widely used because of its fast cooling speed, small deformation, and excellent cladding layer performance. Titanium alloy has the characteristics of low density, specific strength, high specific height, and good corrosion resistance. It is widely used in aerospace, chemical, medical, and sports equipment and other fields. However, the surface cladding and forming of titanium alloys have special requirements. Because of the strong combination of metal titanium and hydrogen, oxygen, nitrogen and carbon in the air, this has caused the complexity of titanium and titanium alloys in smelting and processing. Its smelting and sintering processes are required to be carried out in a high vacuum or ...
