Abstract
The invention relates to an assembling process for a water accumulation prevention flat roof of a railway vehicle. A beam column welding area of the water accumulation prevention flat roof is located on the back face. Two-sided welding needs to be conducted on the front faces of air conditioner supporting beams and middle roof plates, and meanwhile due to the fact that the structure sealing requirement is high, sealant needs to be coated and beaten after welding is completed and the watering test needs to be conducted on the front faces. With welding deformation factors taken into consideration, the process of adjusting and repairing the middle roof plates through roasting is adopted. According to the main process scheme, the reverse installation process is adopted first, forward installation, adjustment and repair are then conducted, and finally the watering test is conducted. The assembling process is easy to achieve, the installation accuracy is high, and the assembling quality is good.
