We are specially in producing Box-column productions line ,such as : steel plate cutting ,Box column assembling Box coulmn SAW welding , Box column hole ESW welding machine etc.
As a professional factory , we often discuss many technical questions with our customers . How to release Box-column or Machine welding stress ? We often adopt VSR （ vibration stress relief ）type。
In the steel forging, machining, casting, welding, machining process, due to stress or uneven heating, internally generated non-uniform plastic deformation, after the end of the process, the internal components are residual stresses. Residual stress is a major cause cracking or deformation of the metal components, which greatly affect the stability of the fatigue strength and dimensional accuracy, and thus the metal member in the process must eliminate the residual stress 。
Bridge box girder welding deformation generated during welding, usually by the application through VSR (VSR) technology to eliminate the residual stress at the welding, improve the dimensional accuracy of the box beam
