Abstract

PURPOSE: To perform highly reliable eutectic pressure welding in quantities by chucking an Al pipe with a ceramic half ring and sliding a Cu pipe and butting it.
CONSTITUTION: In eutectic pressure welding of an Al pipe and a Cu pipe, the Al pipe 1 is chucked with a formed and pressurized half ring made of ceramic or titanium etc. near the butting end face. A Cu pipe 2 is held to allow sliding with a holding roller 10 etc. The Al pipe 1 and Cu pipe 2 are held with a vertically moving cylinder 3, and the tip of Al pipe is positioned at the center of a coil 5 by moving a horizontal cylinder 4. Then, the Cu pipe 2 is pushed by activating a pressure welding cylinder 6, and butted to the end face of the Al pipe 1, a high frequency oscillator 7 is made on and Al-Cu eutectic reaction at the joint is started. By this device, red heat of Al pipe 1 due to Joule heat caused by induced current is prevented, and keeping of pressure and attaching and detaching of the pipe is made easy.
