“If you can’t stand the heat, get out of the kitchen.”
This expression makes absolutely no sense if you’re in the profession of welding.
#1: If you can’t stand the heat, why the heck are you a welder?
#2: There is no kitchen. What kitchen? If you’re welding in a kitchen, get out of that kitchen. Right now! There are gas mains!
#3: If you can stand the heat, and you’re not in a kitchen, then why would you move? Stay right there!
In fact, let’s add some more heat. Let’s add some… friction.
That’s right, you heard me. Friction, as in friction stir welding. FSW. It’s all the rage in… in…
An introduction to friction stir welding

A relatively new joining process, friction stir welding (FSW) produces no fumes; uses no filler material; and can join aluminum alloys, copper, magnesium, zinc, steels, and titanium. FSW sometimes produces a weld that is stronger than the base material.
Friction stir welding (FSW) is a relatively new joining process that has been used for high production since 1996. Because melting does not occur and joining takes place below the melting temperature of the material, a high-quality weld is created. This characteristic greatly reduces the ill effects of high heat input, including distortion, and eliminates solidification defects.
Friction stir welding also is highly efficient, produces no fumes, and uses no filler material, which make this process environmentally friendly.
