Liupengpeng, a Chinese shipbuilding and welding craftsman in Hudong, won the title of "national excellent migrant workers"

one is that it needs special customization. Recently, the leading group for migrant workers of the State Council held a national commendation Conference for excellent migrant workers and advanced collectives in migrant workers' work in Beijing. Liupengpeng, a welding technician of Hudong Zhonghua shipbuilding company, was honored on the list and won the title of "national excellent migrant workers", which only 33 people in Shanghai won.

recently, the leading group for migrant workers of the State Council held a national commendation Conference for outstanding migrant workers and advanced collectives in migrant workers' work in Beijing. Liupengpeng, a welding technician of Hudong Zhonghua shipbuilding company, was honored on the list and won the title of "national excellent migrant workers", which only 33 people in Shanghai won. Liu pengpeng has made outstanding contributions to the shipbuilding industry and has become an excellent representative of thousands of migrant workers in the shipbuilding industry

"national excellent migrant workers" selection activity is organized by the leading group of migrant workers of the State Council for energy affairs, and is held every three years to commend migrant workers with outstanding performance, excellent achievements and good social impact in all walks of life. It aims to encourage the majority of migrant workers to strive for self-improvement, work hard, improve their quality, and forge ahead. At the same time, it creates a strong atmosphere in which the whole society cares for, cares for, and respects migrant workers, and promotes migrant workers to share the fruits of economic and social development

since entering the post, he has always worked hard in this ordinary post, obeying the distribution, being diligent and eager to learn, and mastering excellent welding technology. During the construction of the world's first 38000 ton duplex stainless steel chemical ship, as a seed player, he took the lead in passing the welding certificate of duplex stainless steel, and then as a coach, he guided more than 90 welders to obtain certificates smoothly

use technological innovation to help boutique projects

in the welding of bilge ribs of new ships, in order to seek a breakthrough, Liu pengpeng boldly changed the welding method, and proposed to adopt the form of multi-layer and multi pass symmetrical welding to replace the previous welding form. During welding, the horizontal fillet welding and elevation fillet welding are staggered, so that the bilge ribs are evenly heated, Minimize the welding deformation of bilge reinforcement "We all want to make the building safer and smaller, so that the overall production progress has been improved. New materials have been used in the construction of new ships. In order to solve the problems of low welding efficiency and low qualification rate of special steel on site, he boldly adopted new methods and new processes after a lot of practice, creatively adopted self-made hand-held dual-purpose mask and kneeling with both hands, and solved a series of problems such as low welding efficiency, unstable welding gestures, poor welding quality and so on. He taught more people his original welding methods and trained 300 special steel welders, providing technical personnel guarantee for ensuring the construction node of the new ship

in recent years, Liu pengpeng has made in-depth research on the welding of carbon steel and aluminum bronze. Through research and improvement, manual nickel base electrode arc welding is adopted to overcome the problems of large amount of carburization and large tendency of cracks in traditional welding. Compared with traditional welding methods, the efficiency is increased by nearly 60%, and the practicability is very strong. On the basis of practice, if the dust is relatively large, he needs to find a machine clothes to cover the gap broach to prevent the dust from entering the oil tank foundation. He wrote a paper on the welding method of QA aluminum bronze and No. 20 steel dissimilar materials, which won the gold medal in the 2019 Shanghai worker welding technology paper evaluation
