Hi Nick, I have been a welder for 40 years and still not bored with it, it does depend what sort you do of course. Production welding is easy to learn but tends to be repetitive. If you get on site work you never know what you are going to get. Don't expect to fall into a skilled position straight away it won't happen. Every weld is slightly different maybe that is what is interesting it does require concentration whilst welding, if you are using arc then you have in your hand something hotter than the face of the sun (well not right in your hand obviously).Its a job I would recommend if you don't mind heat,hard work, and getting dirty. Give me a shout on Facebook if you want any help or advice.
