The main thing is to practice more, be steady at present and be suitable. Tell you a trick: welding artificial material ring, the operation skill is the first. It is important to combine hands and brains, and avoid impetuousness and unprofessionalism.
Stiffness of the right hand is a taboo, and both internal rotation and external rotation are time-varying. The vertical and horizontal directions go hand in hand, bearing in mind three points of welding. According to the specification, the assembly before welding is carried out in high-quality dry covered electrode. Arc striking is skillful, and scraping and impact are optional. After arc firing, the core is not in a hurry, so it is very important to preheat the base material.
Extended data:
Mainly divided into arc welding technology and resistance welding technology.
Arc welding technology mainly includes: manual arc welding technology, submerged arc welding technology, tungsten gas shielded welding technology, plasma arc welding technology, metal gas shielded welding technology and tubular wire arc welding technology.
Resistance welding is mainly a welding method with resistance heat as energy source, including electroslag welding with slag resistance heat as energy source and resistance welding with solid resistance heat as energy source.
