What are the residual tension?

Residual voltage is the voltage in the material that is introduced during the processing phase, but lasts after the product is completed, instead of the solution as soon as the voltage source is removed. You could think of residual tension as a tension that remain behind in the components produced. Sometimes these stresses are intentionally introduced to hold parts in tension to extend the life of wear and provide other functions. In other cases, the residual voltage is introduced by accident and are not desirable. For example, the residual voltage of welding is a problem with some metal components. Similarly, the voltage can be created using plastics that are heated and injected. Other processes such as rolling can create similar stresses in materials that are used for shaping or otherwise work.

If the residual voltage is not desired and carefully controlled, it can become a problem. Components may fail due to residual voltage that is not controlled; For example, the screw could blow out without pressure. ResidualThe voltage is sometimes accused of incidents such as bridge failure if no other causes can be determined. This voltage is difficult to measure, especially after the failure has damaged the part, which makes it difficult to study and difficult to distinguish the cause of cracking and other problems.

In other cases, residual stresses are actually searched. A classic example is the stress associated with a hammer in the nail. When the nail is hammered into the wood, the residual tension created by the process is what holds the nail instead of allowing it to jump back. Likewise, blades and other metal components are often produced with residual voltages that reduce cracking and fatigue. In these cases, for determining the required voltage level and control, careful calibrations are made during production, so the components will be created with specified characteristics.

There is a

device that can be used to perform ZBYtko tension. Measurement of such a voltage is complicated because most devices are designed to measure the continuing voltage such as the voltage created using the tool. It is more difficult to measure stress, which is basically locked in a component. Companies that produce devices that can be used to measure residual voltage
