Where is the high salary of riveters and welders?

Almost. At present, the salary of a good riveter is about 6000- 10000, and the salary of a good welder in all positions is about 6000-8000. If you want to learn technology, I personally recommend learning riveting. This job is not boring, you have to use your head. On the contrary, you have to learn welding, but it takes a long time to learn riveting.
