Control of preheating temperature and interlayer temperature
With the thickness of more than 8 mm thick plate welding, preheating before welding, preheating temperature between 80 ℃ ~ 120 ℃, interpass temperature control between 60 ℃ ~ 100 ℃. Too high preheating temperature, in addition to the harsh working environment, may also affect the performance of aluminum alloy, appear joint softening, weld appearance forming bad phenomenon. Too high interlayer temperature will also increase the probability of hot cracks in aluminum welding.
