Analysis of Mirror Surface Treatment Technology for Stainless Steel Surface Drawing Surface brushing/satin Metal wire drawing is a decorative method that is very common in life. It can be made into straight lines, threads, corrugations, chaos and swirls. This kind of surface treatment has the characteristics of good hand feeling, fine gloss and strong abrasion resistance. It has a wide range of applications in electronic equipment, home appliances, and mechanical equipment. Mirror treatment The mirror treatment of stainless steel is simply to polish the surface of stainless steel. The polishing method is divided into physical polishing and chemical polishing. It can also be partially polished on the surface of stainless steel. The polishing grade is divided into ordinary polishing, ordinary 6K, fine grinding 8K, super fine grinding 10K effect. The mirror gives a feeling of high-end simplicity and a stylish future. Spraying Stainless steel spraying is substantially different from the above coloring treatment. Some paints may damage the stainless steel surface oxide layer due to the difference in materials. However, some sprays can be used to achieve different colors of stainless steel products in a simple process, and different sprays can be used to change the feel of stainless steel.

Application of Tungsten Arc Welding in the Welding of Stainless Steel Sheet Welding principle TIG welding is a kind of open arc welding. The arc is stable and the heat is concentrated. Under the maintenance of inert gas (argon), the welding pool is pure and the weld quality is good. However, when welding stainless steel, especially austenitic stainless steel, the reverse side of the weld is also required to stop maintenance, otherwise it will produce severe oxidation, affecting weld formation and welding performance. Welding characteristics The welding of stainless steel sheets has the following characteristics: (1) The stainless steel sheet has poor thermal conductivity and is easily burned directly. (2) The welding wire is not required for welding, and the base material is directly fused. Therefore, the quality of stainless steel sheet welding is closely related to the operator, equipment, materials, construction methods, external environment during welding, and testing. In the welding process of stainless steel sheet, no welding consumables are required, but the following information is requested to be high: First, the purity, flow rate and argon-passing time of argon gas, and second, tungsten electrode. (1) Argon gas Argon is an inert gas and is not easy to react with other metal materials and gases. Because of the cooling effect of the airflow, the weld heat affected zone is small and the weldment deformation is small, which is the most ideal maintenance gas for tungsten argon arc welding. The purity of argon must be greater than 99.99%. Argon is mainly effective for stopping the molten pool. During the welding process, the air is prevented from corroding the molten pool and causing oxidation. At the same time, effective air isolation is stopped for the weld area, the weld area is maintained, and the welding performance is improved. (2) Tungsten The surface of the tungsten electrode should be lubricated, the end must be sharpened, and the concentricity is good. In this way, the high-frequency arc striking is good, the arc stability is good, the melting is deep, the molten pool can be kept stable, the weld bead is formed well, and the welding quality is good. If the surface of the tungsten electrode is burned out or there are defects such as contaminants, cracks, shrinkage holes, etc., the high-frequency arc striking is difficult during the welding, the arc is unstable, the arc is drifting, the molten pool is dispersed, the appearance is expanded, the penetration is shallow, and the weld is welded. Poor forming and poor welding quality. Conclusion 1) The stability of tungsten argon arc welding is good, and the shape of different tungsten poles has a great influence on the welding quality of stainless steel sheets. 2) Flat-tipped taper tip tungsten electrode welding can improve the double-sided forming rate of single-sided welding, reduce the heat affected zone of welding, make the weld bead beautiful, and have better comprehensive mechanical properties. 3) Welding defects can be effectively prevented by using the correct welding method.

How to reduce the occurrence of burrs in the laser cutting production First check if there is a problem with the laser output. Is the spotted spot very round (the circle indicates that the lateral distribution of the laser energy is uniform and the cutting quality is good) Check if the lens in the laser transmission process is dirty, or if the lens is dirty, and the lens has small cracks that are not easily visible to the naked eye, which will affect the transmission of the laser. This is by an adjustment of the process parameters. If the burrs generated after laser cutting of stainless steel have a certain hardness, it is very difficult to take time and affect the appearance. It is best to solve it from the root cause. First of all, the purity of the auxiliary gas is high, and it is very important to change the purity of a gas supplier with a better quality. Then the anti-cutting parameters are adjusted to the best, the focal length, cutting speed, power, running time, etc. Sub-adjustment (please let the professional engineer debug), the parameters provided by the machine can not cut the delicate workpiece, so only after many attempts can the burr be minimized

Sheet metal pieces of hardware that is thin, it is through stamping, bending, stretching and other means to the processing of parts, a broad definition is in the process of constant thickness of parts. Corresponds to the casting, forging, machining parts, etc..

Evaluation of welding and welding process of the use of materials 1, evaluation of welding materials used According to the requirements of the actual working condition and the structure of the corresponding technology, put forward the test items necessary. All welded joints will withstand a certain load (dynamic or static load is less, so any requirements of welding structure, almost all the tests of mechanical properties at room temperature and most of them are for the welded joint, and others in the weld metal. Joint work in high or low temperature conditions, it is necessary to test the corresponding temperature: such as creep rupture strength test, the material to determine the high temperature properties (creep limit and the pupa becomes elongation and creep rate, rupture strength and endurance limit elongation and section shrinkage rate of the corresponding temperature); Charpy V notch impact test to determine the impact of joint under low temperature toughness and impact toughness of the material was measured by the drop weight test; the nil ductility transition temperature. Corrosive conditions in the medium, the corrosion resistance test should be carried out in different (such as resistance to general corrosion, intergranular corrosion, pitting corrosion, crevice corrosion test). In the wear condition wear test shall be conducted accordingly (such as abrasive wear test, wear test, impact resistance and wear test). Aging embrittlement of materials, joint should be thermal strain aging embrittlement sensitivity test. 2, evaluation of welding materials Refers to the evaluation of the welded joints have the tendency of welding defects, to make reasonable welding procedure specification (WPS) support. With steel, for example, is the main chemical composition of materials as the basis for indirect assessment of "carbon equivalent" to the joint and crack resistance test of direct test method.
