The transmission part of the equipment is powered byone group of oil pump , several hydraulic motor and three hydrocylinder drive the work table to achieve rotation, incline and v ice-arm to adjust work table height. The detailed system feature ponents have been introduced in this design to emphasis the cutting edge and reality feature , which been enhanced by the specialty design of its ponent . Weld change site equipment is mainly for welding industry to reduce the w elds the assistance period, enhance work efficiency, reduce utility of labour and improve quality of welding. Most importantly, w eld change site equipment could enhance the effect of almost every sort of welding 。 In the welding production, it can meet the welding frequently to transition and to choose the appropriate welding position the situation, in view of this actual demand. This design the Weld change site Equipment. It has been possible through the work table rotation and incline. It causes the welded joint tobe in easily to weld the position. The w eld change site equipment and the welding operation machine coordination use, can realize the welding mechanization, the automation, enhanced the welding efficiency and the welding quality. Weld change site equipment can be applied in the i
