Manual manual welding is commonly known in hebei iron and steel pipe enterprises, the academic should do manual arc welding.Hand welding that is commonly known as the factory, it is called on academic manual electric arc welding, its principle is: in the gas medium between the two electrodes, a strong and permanent phenomenon of electricity discharge is called arc, arc discharge, on the one hand, to produce high temperature, produce light at the same time, the manual welding is to use arc produced by high temperature melting welding rod and welding pieces, separate the two pieces of metal fusion together, strong coupling is achieved.
Welder, is a special metal welding job in the machinery manufacturing and machining industry, but also a very important position.Manual handlebar welding is most important in the straight joint steel pipe manufacturing enterprises, especially in the coil steel pipe and ring welded butt steel pipe industry.In the circumferential welding butt pipe manual welding welders need to carry out manual pre-welding on the rolled steel pipe, if the project requires X-ray non-destructive inspection, often because of the enterprise's submerged arc automatic welding equipment technical defects with very guaranteed manual manual welding.At present, China's processing manufacturing industry is short of manual manual welding in this aspect of the talent, enterprises, senior blue-collar treatment than white-collar workers.However, manual welding this kind of work to the human body too much damage, such as burning eyes, ultraviolet radiation, toxic gas and so on."Welder" in the light of the practice, service in engineering practice, and a collection of difficult welding knowledge, skills, management and other aspects of knowledge to serve the community.Manual manual welding welders are required to include basic knowledge of welding, welding materials, welding preparation, basic skills of welding process operation, welding deformation correction and defect prevention measures, as well as welding quality management and safety measures.Its principle is: when the artificial hand welding in gas medium between the two electrodes in a strong and permanent phenomenon of electricity discharge is called arc, arc discharge, on the one hand, to produce high temperature, produce light at the same time, the manual welding is to use arc produced by high temperature melting welding rod and welding pieces, separate the two pieces of metal fusion together, strong coupling is achieved.
