If you find a better position, you can go. However, your position is welding engineer. I don't think it's a bad thing to know the actual operation. Graduation from junior college will always come faster than those who have never studied. And you can deepen your theoretical level in practice. Engineers who don't know the actual operation are not good engineers. Engineers who can't solve practical production problems are not good engineers. I just graduated from high school as a welder, and then went to college, majoring in welding. I think practical experience is of great help to my improvement. Several of my college classmates went to work as welders after graduation, and now they are factory directors. At that time (1977 admitted to the university), there were even fewer welding majors, but he came over anyway. There is still a lot to learn as a welder in a shipyard. The key is whether you work hard or not.
