Welders mainly have four kinds of certificates: grade certificate, operation certificate, special equipment welding certificate and building welding certificate.
Grade certificate and special equipment welding certificate are not mentioned for the time being. Many people think that the welder's operation certificate is similar to the construction welding certificate, and they can't tell the difference between them.
Welder's operation certificate, the scientific name is "welding and hot cutting operation certificate", also known as "employment certificate", is now issued by the emergency management bureau. It is a necessary certificate for welders to work. Without certificates, they can't work.
The certificate of construction welder is managed by the construction department in a unified way, and is mostly used in the construction site. It is a necessary qualification certificate for welders engaged in the construction industry.
What's the difference between them? Listen to Changsha Huide Education in detail!
1, different jurisdictions
As mentioned above, the welder's operation certificate belongs to the emergency management department, and the building welder's certificate belongs to the housing and construction department, which are managed separately in two completely different jurisdictions.
However, this has also caused a drawback: there is a problem of repeated verification.
The operation of welder's operation certificate and construction welder's certificate is actually the same, which proves that welder is qualified to operate.
However, due to different jurisdictions, the two departments have their own checks. Therefore, if welders are engaged in welding operations in the construction industry, they should not only take the construction welding certificate, but also take the welder's job certificate.
This problem has also been criticized by the majority of welders and is expected to be solved in the future.
2, the scope of use is different
The welder's operation certificate is for all welders and can be used in all walks of life.
Construction welder certificate can only be used in construction sites or construction. Compared with the welder's operation certificate, the scope of application is not so wide.
3. The validity period of certificates is different.
The welder's operation certificate is valid for 6 years and needs to be reviewed every 3 years.
The service period of the certificate of construction welder is 6 years, and the validity period of the certificate is 2 years. After the expiration of the validity period, the review shall be postponed.
