We should be scrapped for wear hooks, otherwise if we continue to use it and major problems occur, the consequences are not something we can afford. However, there are also some ways to go to the front of the sword.

There is a treaty that it has clearly stipulated: "When the height of the vertical section of the hook exceeds 10%, it should be scrapped and shall not be used for welding."

This provision is undoubtedly correct before the unified welding supplementary process rules are promulgated.

However, among some small and small enterprises, because the unit does not have the ability to make hooks and has no hook hooks, when the hook is worn more than 10%, in order not to affect the normal production of the enterprise, it is often used. The method is used to restore the safety starting coefficient of the hook.

Although this violates the relevant regulations, through the on -site use of some units for many years, no accidents have been caused by replenishment.

Of course, this measure does not rule out the possibility of accidents. We need to scientifically analyze and study the welding method to further verify the feasibility of this method.

After a series of experiments, it is proved that the hook of replenishment does not have a great impact on future use, but the premise is that all aspects of the material process of replenishment are relatively high, and ordinary users should not adopt this method.
