A good diary to write about tired welders

Since entering the factory in xxxx, I have been engaged in welding operation technology. In 1996, he obtained the boiler and pressure vessel welder certificate through the training and examination provided by the Municipal Labor Bureau. Because I usually work diligently and hard, I was selected by the company to be sent to the Chemical Machinery Factory of Nanhua Group Company in October 1996 to study manual tungsten arc welding for four months. In the same year, I obtained the argon arc welding certificate. In order to improve the company's welding technology level, the company recommended me to go to Hangzhou Boiler Factory for a one-year training in welding technology and CO2 operation technology in 1997. So far, I can perform five types of welding operations: electrode arc welding, argon arc welding, gas welding, CO2 gas shielded welding, and submerged arc welding. At the same time, I have eight qualified projects in electrode arc welding and submerged arc welding.

In order to put what I have learned to use, I have participated in the welding work in the trial production process of our company's new products (15T, 20T steam boilers) since 1998. During the trial production process, I proposed my own plan and received Approved by the company, the welding qualification rate reached 100% after hydrostatic testing. In October of the same year, he was entrusted by the company's welding laboratory to conduct a primary forming test of argon arc welding of smoke pipes. After his own theoretical discussion and overtime operation training, he compiled a complete set of smoke pipe butt welding processes, thus providing The company made its own contribution to the reference utilization of manufactured products and reduced production costs, and was commended by the original factory department. From 1999 to 2000, I used CO2 gas shielded welding to replace manual arc welding for the company's 10T and 6T fin tubes, which increased the work efficiency by 2 to 3 times, and the technology was relatively advanced. This welding method and technology have been recognized by the company. During the trial production of the 2T and 4T oil-fired boilers currently produced by our company, the complexity of the product structure brought great inconvenience to the welding. I actively cooperated with the technology, process, and production departments to personally participate in the steam drum production and circulation process. For arc welding and argon arc welding, the pass rate of the weld seams through X-ray flaw detection is 100%. We also mastered first-hand information on the process parameters during the production process, which provided a basis for writing process flow cards. In recent years, I have also assisted the process department in the company to conduct welding process assessment and participated in the preparation of welding processes. During this period, I wrote the pipeline welding process for the company's industrial boiler installation. At the same time, in view of the characteristics of our company's current product structure, and based on my daily accumulated practical experience, I compiled a book "Welding Safety Operation Technology", which was approved by the company's research institute and used as a training material for welders in our company's welding test room to guide new welders in safe operations. Technology has helped.

I left the boiler factory in 2006 and became a member of xxx Equipment Manufacturing Co., Ltd. in 2006. In the past two years of training in the company, I have been hardworking and hardworking, and the welding quality is stable and excellent. It was well received by the leaders of this unit. In the future, I will continue to make progress, not only do my own job well, but also do a good job of communicating, helping and leading, giving full play to my talents, making more contributions to the company, and further improving the company's welding level.

Since I joined hydropower work in 1977, I first participated in the construction of Baishan Hydropower Station and Hongshi Hydropower Station, and then successively invested in the Tianhuangping Pumped Storage Project in Anji County, Zhejiang Province in 1993. Neng Power Station, Shanxi Power Station in Wenzhou, Zhejiang, and Tongbai Pumped Storage Power Station in Tiantai County, Zhejiang. I have been engaged in this type of work since I started working. During these years of work, I have been engaged in electric welding, gas welding, gas cutting, etc. according to the requirements of the construction drawings. I have mastered the basic principles of electric welding and cutting and some construction specifications for electric welders. regulations; be able to deeply understand and master the safety technical measures of this type of work through a detailed understanding of the characteristics of the welding and cutting production process and welding processes, tools and operating methods, strictly implement safety regulations and implement protective measures to ensure safe production ; And can actively promote and apply new technologies, new processes, new materials and new equipment in construction, thus continuously improving their business capabilities. He has been rated as the bureau's advanced production worker and production expert many times, and has contributed to the survival and development of the Seventh Branch.

In 1995, the Seventh Branch established the 8# mixing system at Tianhuangping Pumped Storage Power Station in Anji County, Zhejiang Province. At that time, there were few technicians and weak technical strength. The leader assigned me to be the leader from production to Fully responsible for installation and commissioning. After receiving the task, I obtained the drawings from the Engineering Technology Department and read through a large amount of information overnight to analyze and identify the drawings, thereby estimating the amount of raw materials and the construction status of the site. Early the next morning, we worked with comrades from the Engineering and Technology Department to analyze and study possible problems that may arise during the construction. Due to thorough consideration in advance, careful thinking, and effective construction measures, it only took 90 days from production to installation, debugging to production. It was completed 20 days ahead of schedule, and the task was completed excellently. Especially in the unit project of welding and installation, the one-time acceptance rate reached 100, which greatly improved production efficiency and saved labor time. After the successful completion of the 8# mixing station, I was tasked with the construction of the 5# mixing station. With the previous construction experience, I can say that I am confident about this work, but there is an objective factor. In the hot summer, faced with the scorching heat of the southern climate, heavy rainfall and many other unfavorable factors, the originally sufficient construction period seemed a bit tight. Based on this series of situations, I boldly formulated a feasible technical construction plan, starting early and working late at night, reducing construction links that were interrupted at noon, arranging the workload that required welding and cutting to be completed in the morning shift as much as possible, and arranging the installation that needed to be done in the afternoon. It was completed. Due to the proper time arrangement, there was not a single case of heat stroke in the hot summer. Not only did the construction period not be delayed, but the task was completed in 15 days. In the joint acceptance of the design, supervision, and relevant departments of the branch, it received a very high evaluation, they said : "Your welders' skills are excellent, and your welding and installation are trustworthy."

In 2001, the Seventh Branch won the bid for the Tongbai Pumped Storage Power Station in Tiantai, Zhejiang Province, and undertook the excavation and concrete engineering of the C2 standard water transmission system of the power station. In the unit project of excavation of the straight section of the inclined shaft, I was responsible for the welding and fabrication of the expansion trolley; in the unit project of the sliding form lining of the straight section of the inclined shaft, I was responsible for the welding and fabrication of the formwork. These two tasks are very special operations of the same type, and both are completed in inclined shafts. The expansion trolley and sliding formwork are both welding and installation of large metal structures. The welding workload is very large, because in the The thickness, structure and installation conditions of weldments during welding are different, resulting in many types of welded joints. Butt joints, T-joints, corner joints and lap joints all appear with high frequency, and the operating conditions are very poor: first of all, underground The light depends entirely on lighting, breaking the conventional lighting conditions; secondly, the air quality underground is very poor. Due to poor air mobility and limited ventilation conditions, it is difficult to eliminate toxic gases, harmful dust, etc. generated during the welding and cutting process in a timely manner. And eliminate, at the same time, the arc radiation, high-frequency electromagnetic fields, noise and rays generated during the operation are also very harmful to the body; and the most important point is that there is a risk of falling in underground operations, which brings great harm to the operation. difficulties.
