Stainless steel metal bellows is used in laser welding of stainless steel metal bellows in the process of movement between the flange and will have a strong impact, coupled with other factors, can cause fatigue and cracking of the sealing surface damage, which occurred leak situation. Not only caused the resources, pollute the environment, but also affect the production and operation of equipment. This is a result of the welding manner. If you use a laser processing it? With this question we then carried out the following experiment. Experimental conditions and methods of use of austenitic stainless steel flange above through holes distributed a dozen experimental device is a continuous wave laser, test pieces coated alloy, followed by heating. Laser power of 2KW, slower then focused with a mirror, a second laser power 1.7KW, flame velocity constant heat compensation, lowering the annealing temperature. Then use the microscope and other observation equipment for scanning. The results of the present after the laser cladding of stainless steel metal bellows substrate binding region in a narrow white band, this one bonding layer solution, expressed its excellent performance, the cooling fast, resistant to bending-type bellows best quality, will produce a very fine crystal structure after crystallization. Stainless steel metal bellows laser detection, you can make good quality and get a no cracks, holes and other defects in the product, good appearance and uniform hardness, is an ideal means of processing. Process Chemistry Nickel alloy metal bellows as follows. 1. machined aluminum mold according to the design requirements of the geometric shape and size, machined aluminum mold, aluminum mold requires precise size, resistant to bending shaped bellows ease of use and seamless finish, peaks and valleys smooth arc connection, without acute and marks such defects. 2. pretreated prior to deposition of aluminum die before the chemical deposition must be thoroughly to remove oil, dust and dirt, resistance to bending corrugated pipe, but also must be sensitized etching process, so as to obtain a uniform aluminum mold, compact , combined with a solid deposited layer 3. Chemical Nickel alloy Lin select the appropriate solution composition and process conditions, depositing a layer of the desired thickness and chemical composition of the nickel-phosphorus alloy aluminum die elasticity, excellent resistance to bending corrugated pipe manufacturer, so as to meet the performance requirements of the bellows. 4. Hirth, perforated aluminum mold according to design drawings cut end surface of the deposited layer, then drilled through the center portion of the aluminum mold having a pore diameter of not damage the trough sedimentary layer is limited. 5. The chemical dissolution of the mold release lye dissolved aluminum mold, and the rest of the bellows-shaped housing nickel-phosphorus deposited layer. 6. Heat treatment Nickel alloy metal bellows through appropriate heat treatment to eliminate stress, so that fine particles into the crystal structure of amorphous pull amorphous structure, thereby obtaining a high elastic nickel alloy metal bellows.
