Galvanized steel is a new type of steel synthesized from ordinary carbon steel after special galvanizing treatment. It can effectively prevent steel corrosion and thus prolong the service life just now. Today, the small edition of Qianye New Material
Co., Ltd., our color coated plate manufacturer, will expand for you. Let's talk about laser galvanized steel.
The advantages and processing mechanism of Nd:YAG laser in filler wire welding of galvanized steel sheet are discussed. After analyzing the experimental results, the process test proves that under suitable conditions, laser brazing with filler wires can obtain joints with good forming, fewer defects and qualified performance. Automobile industry products have the requirements of high efficiency, high reliability and high integration. Hot-dip galvanized steel sheets for automobiles are the best products in galvanized steel sheets. Since 1975, hot-dip galvanized sheet was first used in automobile industry in the United States for more than 20 years. In order to meet the requirements of high quality and high performance of galvanized strip, fingerprint-resistant surface treatment technology has emerged in recent years.
The small edition of Qianye New Material Co., Ltd., a manufacturer of color coated sheet, has learned that the development history and research status of fingerprint-resistant technology at home and abroad. Starting from the chemical properties of coatings, their types, composition and application examples are introduced respectively. Finally, the research prospects of fingerprint-resistant technology are prospected, and it is considered that the fingerprint-resistant Technology is durable. Fingerprint processing technology is a technology with broad prospects for development, and will become a research hotspot in the near future. Galvanized steel is widely used in various fields because of its good corrosion resistance, and the existence of galvanized layer greatly reduces the weldability of galvanized steel. Laser welding is a new method to realize galvanized steel welding. There are two special welding characteristics of zinc vapor and zinc plasma in laser deep penetration welding of galvanized steel.
The fundamental problem of laser welding of galvanized steel is the influence of zinc vapor on welding process. Reducing zinc vapor evaporation and smoothly discharging zinc vapor are the fundamental ways to reduce the influence of zinc vapor. Around the key technology of laser welding of galvanized steel, various processes and methods for improving the quality of laser welding of galvanized steel are discussed, including seeking specific process measures, optimizing process parameters, simulation optimization of welding process and on-line detection and control.
Aove is a brief introduction of laser galvanized steel, you can understand, after all, knowledge is not too much.
