Through orthogonal experiment, laser power, scanning rate and gas flow were optimized and pretreatment techniques were adopted to cancel pore and crack in laser weld of LY12CZ.
The fluctuating wind loads on a dome-like roof are reconstructed based on the synchronous multi-pressure scanning technique of wind tunnel tests and the proper orthogonal decomposition(POD)method.
