Large torque electric wrench is mainly used in steel structure industry to fasten large hexagon bolts with torque requirements. Is the larger the torque, the better? What is the proper torque for the electric wrench?

在施工中，使用电动扭矩扳手控制施工扭矩具有很重要的意义。

In construction, it is of great significance to use electric torque wrench to control construction torque.

高强螺栓除了剪切力和拉力之外，还会受到振动、温度、侧向应力(风力、流量、压力等)、负载的改变等其他的一些作用力。

In addition to shear force and tensile force, high-strength bolts will also be subjected to vibration, temperature, lateral stress (wind, flow, pressure, etc.), load change and other forces.

电动扭矩扳手扭力其实并不是越大越好，需要根据螺栓的大小来设定必威西汉姆联官网g1线路的扭矩值，如果所设定的扭矩值偏小，就会造成紧固不足，螺栓就会因振动或循环载荷而松脱，如果紧固过度，用力不均匀会是法兰转动使钢结构断裂。所以要按标准扭紧连杆螺栓,千万不能认为越紧、力量越大越好。

In fact, the greater the torque of the electric torque wrench, the better. It is necessary to set the torque value of the electric torque wrench according to the size of the bolt. If the set torque value is too small, it will cause insufficient tightening, and the bolt will loosen due to vibration or cyclic load. If the tightening is excessive and the force is uneven, the flange rotation will break the steel structure. Therefore, tighten the connecting rod bolts according to the standard. Never think that the tighter and the greater the force, the better.
