What is Welding?

Welding is the process of joining metals by melting the parts and then using a filler to form a joint. Welding can be done using different
energy sources, from a gas flame or electric arc to a laser or ultrasound. http://www.vrlog.com.cn/what-is-welding.htm

Really not a real good explanation as Forge Welding, described in the URL requires no filler metal; Spot welding uses no filler metal and friction welding uses no filler metal. There are probably other welding techniques that use no filler metal.
