【Abstract】 In this paper a new method for preventing welding hot crack of aluminum alloy, the synchronous rolling method, is put forward, and its principle is expounded. The strain field produced during synchronous rolling is simulated by moire fringe method, and the experiment of synchronous rolling for preventing welding hot crack of aluminum alloy is performed. The results indicate that welding hot crack can be prevented effectively by synchronous rolling during welding.更多还原
