In order to apply what I have learned, I have participated in the welding work in the trial production of our new products (15T and 20T steam boilers) since 1998. During the trial production, I put forward my own scheme, which was recognized by the company. After the hydrostatic test, the welding qualification rate reached 100%. In the same year 10, entrusted by the company's welding laboratory, we carried out the argon arc welding forming test of the flue pipe. After our own theoretical discussion and overtime operation training, we compiled a complete flue pipe welding process, which made our own contribution to the company's manufacturing products and reducing production costs and was commended by the original factory. 1999-2000, our company 10T and 6T finned tubes used CO2 gas shielded arc welding instead of manual arc welding, which improved the working efficiency by 2-3 times and advanced the technology. The welding method and technology have been recognized by our company. At present, in the trial production process of 2T and 4T oil-fired boilers produced by our company, the complexity of product mechanism has brought great inconvenience to welding. I actively cooperated with the technical, technological and production departments, and personally participated in covered electrode arc welding and argon arc welding during the production and circulation of the drum. The pass rate of X-ray flaw detection of the weld was 65,438+000%. The first-hand information of process parameters in the production process is also mastered, which provides a basis for writing process flow cards. In recent years, he also assisted the process department in welding process evaluation and participated in the compilation of welding process, during which he compiled the pipeline welding process in the installation of industrial boilers in the company. At the same time, according to the characteristics of our company's current product organization and my accumulated practical experience, the book "Welding Safe Operation Technology" was compiled, which was approved by the company's research institute as the welder training textbook of our company's welding laboratory, and played a certain guiding role in the safe operation technology of new welders.
I left the boiler plant in 2xxxx and became a member of xxx Equipment Manufacturing Co., Ltd. in 2006. In the company's nearly two years of tempering, I have been diligent and willing to work, and the welding quality is stable and excellent, which has been well received by the leaders of this unit. In the future, I will continue to forge ahead, not only do my own job well, but also do a good job of passing, helping and leading, give full play to my talents, make more contributions to the enterprise and further improve the welding level of the enterprise.
Since 1977, I have participated in the construction of Baishan Hydropower Station and Hongshi Hydropower Station. 1993, I successively joined Tianhuangping Pumped Storage Power Station in Anji County, Zhejiang Province, Shanxi Power Station in Wenzhou, Zhejiang Province, and Tongbai Pumped Storage Power Station in Tiantai County, Zhejiang Province. I have been engaged in this kind of work since I worked. Over the years, I have been engaged in welding, gas welding and gas cutting according to the requirements of construction drawings, and have mastered the basic principles of welding and cutting and some construction specifications of welders. Through a detailed understanding of the characteristics of butt welding production technology, welding technology, tools and operation methods, we can deeply understand and master the safety technical measures of this type of work, strictly implement safety regulations and protective measures, and ensure safe production; And can actively promote and apply new technologies, new processes, new materials and new equipment in the construction, so as to continuously improve their business capabilities. He has been rated as an advanced production worker and expert of the Bureau for many times, and has made contributions to the survival and development of the Seventh Branch.
1995, No.8 mixing system was established in Tianhuangping Pumped Storage Power Station in Anji County, Zhejiang Province. At that time, there were few technicians and weak technical force, so the leader appointed me as the person in charge of the whole process from production to installation and even debugging. After receiving the task and getting the drawings from the engineering department, I read a lot of materials overnight to analyze and read the drawings, so as to budget the amount of raw materials and the construction of the site. Early the next morning, I analyzed and studied the possible problems in the construction with the comrades in the engineering department. Due to thorough consideration in advance, careful thinking and effective construction measures, it took only 90 days from production to installation, commissioning and commissioning, and the task was completed 20 days ahead of schedule. Especially in the unit project of welding installation, the one-time acceptance rate reaches 100%, which greatly improves the production efficiency and saves money. After the successful completion of the 8# mixing station, I received the notice of the establishment of the 5# mixing station. With the previous construction experience, I can say that I have a good idea about this work, but there is an objective factor. At that time, it was a hot summer. Faced with the hot climate in the south, high temperature and heavy rainfall, many unfavorable factors existed, which made the original sufficient construction period seem a little tense. According to this series of situations, I boldly formulated a feasible technical construction scheme, adopted the practice of getting up early and greedy for the dark, reduced the construction links interrupted at noon, arranged the workload of welding and cutting as early as possible, and arranged the workload of installation as much as possible in the afternoon. Due to the proper time arrangement, there was no heatstroke and no delay in the construction period in the hot summer, and the task was completed in 15 days. In the joint acceptance of design, supervision, sub-bureau and other relevant departments,
In 200 1 year, the Seventh Bureau won the bid for Tongbai Pumped-storage Power Station in Tiantai, Zhejiang Province, and undertook the excavation and concrete works of the water conveyance system in C2 bid of the power station. In the unit project of straight section excavation of inclined shaft, I am responsible for welding and manufacturing the bottom-expanding car; I am responsible for the welding and fabrication of formwork in the sliding form lining unit project of straight section of inclined shaft. These two tasks are extremely special operations of the same type, both of which are completed in inclined shafts. Both the under-reamed trolley and the slipform are large metal structures welded and installed, and the welding workload is very heavy. Due to the different thickness, structure and installation conditions of weldments in welding, there are many types of welding joints, such as butt joint, T-joint, angle joint and lap joint, all of which appear at high frequency, and the working conditions are very poor: First, the underground light depends entirely on lighting. Secondly, the underground air quality is very poor. Due to poor air mobility and limited ventilation conditions, it is difficult to neutralize and eliminate toxic gases and harmful dust generated during welding and cutting in time. At the same time, arc radiation, high-frequency electromagnetic field, noise and radiation generated during operation are also very harmful to the body. The most important point is that underground operation is in danger of falling, which brings great difficulties to the operation.
