铝钢异种金属CMT焊接变形研究
Welding Deformation Study of Steel and Aluminum Metal Plate Using CMT
摘要
Abstract
Aiming at the shortcomings of the aluminum steel dissimilar metal sheet in the use of CMT(Cold Metal Transfer)welding,such as the welding heat deformation,poor welding quality,performance etc.,SYSWELD was used to simulate the welding process of sheet metal.Through the combination of different parameters,the welding deformation of thin plate in X, Y and the overall direction was obtained.The results showed that: in the premise of welding requirements,the welding time and welding current should be minimized; in a certain range of welding voltage, the greater the welding voltage,the greater the welding deformation during the same time, the value is about 1.5 times of the X direction of the welding deformation of Y direction; in order to avoid excessive welding deformation, relatively large welding speed should be selected.关键词
