Tell me about shipyard welding.

Manual arc welding and carbon dioxide welding are welding tools, which can be used for plane welding, vertical angle welding and horizontal welding. It's good to go to the shipyard to learn electric welding. You can stand or squat. Welding all day is a little tired. Learning electric welding is very simple. Mastery depends on your talent. Some people learn quickly. I only studied for a month, and the cumulative time is no more than 20 hours. My skills are better than others for two or three years. Have a good relationship with the master. Master will teach you things that books can't learn!
