　　加盖自卸垃圾车的盖板使用的结构为骨架加蒙板的结构，由于盖板尺寸较大，焊缝较长、较多，在焊接盖板的过程中由于焊接位置的温度急剧升高，蒙板将不可避免地产生焊接变形，这是影响结构设计完整性、制造工艺合理性和结构使用可靠性的关键因素。文章对产生焊接变形的原因及控制方法进行了分析。

The cover plate of the cover dump garbage truck use to skeleton structure with mask structure, Due to plate size larger, weld seam longer and more, in the process of welding cover plate due to welding position of the cover plate due to a sharp increase in the temperature, the cover plate will inevitably produce welding deformation. It is a key factor to affect the integrity of the structural design manufacturing processes and structure of the key factors of reliability. The article will to anal-yse generating the causes and controlling method of welding deformation.
