On April 29, 2016, after eight months of continuous technical breakthroughs by Aerospace Engineering and Equipment Corporation, we successfully achieved the welding of small radius, high thickness aluminum alloy conical parts. Small radius, high thickness and high strength aluminum alloy conical parts are key components of a domestic customer. Due to defects such as poor quality stability and low product qualification rate of traditional integral casting molding, the company's personnel and customers repeatedly communicated to determine the molding process of the product. Divided into: stage casting + friction stir welding. Among them, friction stir welding technology is the first application in this product and there is no mature application program. The application of friction stir welding in this product has the following difficulties: 1. "Keyless hole" welding of small-diameter annular seams; due to the inherent characteristics of the equipment, the distance of this pumping is short, and the requirements put forward on the process are high; 2. The rigidity of large-thickness welding is required; after repeated welding, under the premise of certain welding process parameters, the lateral thrust is large, and a strong rigid support is required; 3, welding procedures; welding procedures are different from the machining program, the program adds the welding process requirements. The equipment company organized relevant personnel to carry out a comprehensive system development from various aspects such as equipment, procedures, tooling, and processes, and successfully developed the first heavy-duty, servo-recoverable servo A/C double-swing head friction stirrer, which successfully welded the cone. The reliability of the equipment was verified and the feasibility of the friction stir welding technology applied in the product was also verified. Inspection of the mechanical properties of conventional parallel specimens and X-ray film inspections of the products showed that the products were qualified for welding. Also known as electronic chemical materials. Generally refers to the electronics industry uses specialized chemicals and chemical materials, that is, electronic components, printed circuit boards, industrial and consumer production and packaging of various chemicals and materials. It can be divided into substrates, photoresists, electroplating chemicals, packaging materials, high purity reagents, specialty gases, solvents, pre-cleaning dopants, flux masks, acids and etchants, electronic adhesives and auxiliary materials Other categories. Electronic Chemicals with many varieties, high quality requirements, small dosage, demanding on the cleanliness of the environment, product replacement fast, large capital investment, higher value-added products, etc., these characteristics with the development of micro-processing technology more and more obvious.
Electronic chemicals, also referred to as electronic chemical materials, refer to the fine chemical materials that are used in the electronics industry. The electronic chemicals are a kind of special chemicals. As far as the properties of the production process are concerned, they belong to the fine chemical industry. In terms of product use, Belongs to the electronic material industry. According to the classification standard of China's national economy, the electronic chemicals industry belongs to "Specialized Chemical Products Manufacturing Industry" (2662); according to the "Guidelines for Industry Classification of Listed Companies" promulgated by China Securities Regulatory Commission in April 2001, it belongs to "Specialized Chemical Products Manufacturing Industry" C4360 ). They include integrated circuits and discrete device chemistries, such as chip production photoresist, ultra-clean high-purity reagents, ultra-clean high purity gas, plastic packaging materials; color TV with chemical materials, such as color phosphor, CPT Supporting the water-soluble resist, high-purity inorganic salts, organic films, etc .; chemical materials used in printed circuit boards, such as dry film resist, ink, chemical and electroplating copper plating solution and its additives, surface mount process conductive paste , Cleaning agents, liquid solder resist photoresist, adhesive patch, conductive adhesive, solder paste, pre-coated flux, clean and water-based process flux; liquid crystal display devices with chemical materials, such as liquid crystal, photoresist , Oriented films, adhesives, slurries, electrolytes, films and encapsulants, polarizers, etc .; polishing materials, ect.
