HAMMER WELDING?

- is that goofy term still hanging around?
- I use a torch to weld with, not my body hammer.
- I could never get my hammers hot enough to weld with.
- They never break, so I don't have to fix them.
- I tried to hammer the metal together but it never held.
- My blacksmith heats the metal to a white heat in the forge, and then
- hammers it tightly together,  and this is called "forge welding." ---(But Frank Turley calls it a "forge glue.")

Hammer welding is a "hotrod term", based on the mischief that if you hammer on hot glowing steel that has been previously welded with either torch or TIG, then you are "hammer welding"...you see the logic? Hammering on a hot weld means "hammer welding"?

I never have figured out what they label it when I hammer hot steel way far from a weld. Traditional metalmen label hotworking methods as, "hot planishing", where the metal is smoothed when hot. "Hot shrinking" where the metal is shrunk, and "hot stretching" where...you guessed it...the metal is stretched. These terms are used professionally by many, but "hammer welding" is a cause for laughter amongst the true metalmen. Decades ago, some guy must have walked by a blacksmith's spreading chestnut tree and saw him forge-welding and then saw a body man heating and beating a fender and figured out the new term for both: "hammer welding." ...And both of those craftsmen must have laughed when they heard it. But it stuck.
