Edit: One other thing is that I'm concerned about the future. Like, what if we start using wireless tech and electricians become obsolete? We will still be welding. Just a thought.

As they improve adhesives, there is less and less welding every year. They also use non-metallic piping in many applications that were welded pipe in the past.

Soldering and brazing copper piping is going to be obsolete soon. Every job we are on all copper pipe is crimped with a pro press now.

Orbital welding machines are also doing a lot of the welding now days.

30 years ago there was an approved adhesive to use in place of solder on domestic water, but I don't think it ever took much of the market.
