Fracture analysis of 3003 aluminum alloy welded tube
The cause of the fracture of the 3003 aluminum alloy welded tube was found out through SEM and OM observation of fracture morphology,energy spectrum analysis,metallo-graphic analysis and grain observation.The results show that excessive welding temperature causes localized overheating of the aluminum tube,resulting in internal stress on the sub-strate and ultimately leading to cracking of the 3003 aluminum tube.
