The certificate issued by which department is the welder's certificate is introduced as follows:

Welding certificates are currently divided into three types:

1) welder's special operation certificate issued by emergency management bureau.

It is a necessary document for employment. You don't work without a certificate. The certificate comes with a magnetic card, which is common throughout the country.

2) Certificate of Special Equipment Operators issued by the quality and technical supervision department. It is also called "high pressure welder certificate" or "pressure vessel welder certificate" in the industry.

High-pressure welder, test sub-items, what material, what position and what type of weld can be welded are all shown in the qualified items. You can choose the examination items according to your work needs. Personnel engaged in this kind of work also need to show their certificates. The welding certificate of pressure vessel shall be issued after examination by the Technical Supervision Bureau.

Welders who have no welding certificate for pressure vessels cannot engage in the welding of pressure vessels and pressure pipelines.

3) The welder's grade certificate issued by Ministry of Human Resources and Social Security is a proof that workers have the necessary knowledge and skills to engage in a certain occupation. It is the qualification certificate for workers to apply for jobs, take up posts and start businesses, the main basis for employers to recruit workers, and the effective certificate for overseas employment and foreign labor cooperation personnel to notarize their skill level.

There are five grades: junior worker, intermediate worker, senior worker, second-class technician and first-class technician. In some units, professional grades are linked to job grades. This certificate is needed according to my actual situation, and I will take it again if necessary.
