Shipyard apprentices must be selected. Shipyard welders have high technical requirements and will come into contact with many weldments, such as pipes and decks. You can do almost any welding work in the shipyard for two years. Most of them are flat welding in steel structure, and few are overhead welding and vertical welding, so the technical content is not great. You may not be able to work in the shipyard after working in the steel structure for several years. The steel structure is mainly welded firmly, and the pipeline welding in the shipyard should be firm and leak-free, and can withstand certain pressure. That technology can be understood at a glance. Of course, the working conditions in the shipyard are very difficult, sometimes working in the cabin, the scope of work is narrow, and the outdoor work is windy and sunny, but his technology is really first-class. The welders in shipyards, power plants and chemical enterprises are the best.
