Brazing would work. Welding any 4130/40 that thick is going to need
pre-heat and, probably, post-heat.
Here's an article on welding 4130 that we published last year. It took
me a year to squeeze this article out of the experts. I was frustrated
for years by the vast amount of bull that's been published about
welding 4130, and I finally got to the right guy at Hobart:

I've always been a fan of brazing, probably because an old-timer taught
me and it's a go-to for me.
