Friction (stir) welding is pretty new to common usage, and a very pricey way to go, so I don't think there's many books out there since the market will be very small. I know Boeing has been doing a lot of R&D on the subject to make aerospace parts. No doubt very expensive, and you pretty much have to have a major cost savings or other benefits to invest in that kind of stuff. I've examined some of the welds during a demo of sorts and was highly impressed, but it's not without its drawbacks, not counting investment. Tends to leave a bit of a ridge along both sides of the weld that requires machining off, so that's another process. I did a quick google on friction stir welding and got a lot of good stuff, including several firms that engage in that process.
