Need advice for my son!

[ilovemyfamily]

Hi, I'm Emma. My son was suffering from dyslexia during his early ages. He has improved a lot and really he is a gem, he accepts the fact that he is different from his friends when it comes to academics. I'm a single mom, and I have given him all freedom to choose his career. Now he has decided to go to a welding school, as he is not interested to pursue a college degree. I guess welding is a good option to start earning a good living, though not sure. At the same time, there are life-threatening risks, that are pulling me back. But he badly wants to go for it, so I thought to seek suggestions from the experienced people here.
My question is - Is it a safe profession?
How much demand is there for a career like this ??
I'd be grateful for your thoughts about this - especially if you are an existing and experienced offliner.
