Abstract A liquid-phase diffusion welding technology for Al-base composite materials features that two Al-base composite materials are used for butt or overlap welding. The high-strength diffusion welding can be realized when the welding temp in diffusion is chosen correctly to be any temp in some temp region higher than "some critical temp" in liquid or solid phase temp region of Al-base material. Said critical temp and said temp region vary with the Al-base material and reinforcing material.
