Can the welder's operation certificate be covered by the boiler and pressure vessel welding certificate?

Boiler and pressure vessel welding certificate is a kind of qualification certificate, which can be used to weld pressure vessels. Of course, general welding work is included. Senior welder's certificate is a grade certificate, which indicates the welder's level, while welder's certificate is a special operation certificate and a qualification certificate. Without that welder's certificate, you are engaged in welding, and the relevant departments are not allowed. \x0d\ Types of welders with certificates in China \x0d\ The technical level of welders is related to the safe operation of industrial, civil and national defense facilities, the quality of infrastructure construction and the safety of people's lives and property. Therefore, all industries have strict requirements for welders to hold certificates. At present, there are four kinds of welder certificates: national professional qualification certificate, welding operation certificate for special equipment of boilers, pressure vessels and pressure pipes, safety operation certificate for metal welding and cutting, and international welder certificate. Now, briefly introduce these four certificates. \x0d\ 1。 National professional skill qualification certificate for welders: issued by the Ministry of Labor and Social Security. As we all know, in the era of planned economy, China divided the technical level of workers into eight grades with reference to the methods of the former Soviet Union. After the reform and opening-up, in order to keep up with the international standards, the national vocational qualification system was implemented, which was divided into five grades: primary (national vocational qualification level 5), intermediate (national vocational qualification level 4), advanced (national vocational qualification level 3), technician (national vocational qualification level 2) and senior technician (national vocational qualification level 1). Comprehensive evaluation according to welding length of service, technical level and other factors. Due to historical reasons, some certified personnel failed to meet the national professional standards, such as graduates from our technical school. According to the national professional standards, the skills of intermediate welders must be formed by welding two plate-shaped specimens and one tubular specimen on one side. Acceptance criteria include surface and internal quality. Due to economic reasons, few secondary school graduates meet the national vocational standards (referring to welding graduates), and these people have obtained intermediate qualifications. Coupled with other factors, there are fewer qualified certified personnel, which leads enterprises, especially some industries with high technical requirements, to basically not use this certificate as the basis of welder's technical level when recruiting personnel. However, because this certificate is a national vocational qualification certificate, the national documents clearly stipulate that employees employed by enterprises must hold this certificate. After all aspects are standardized, the gold content of this certificate will be improved. Will eventually become a leading certificate. \x0d\ 2。 Qualification certificate of special equipment for welding boilers, pressure vessels and pressure pipelines (now changed to "People's Republic of China (PRC) Special Equipment Operator Certificate"), indicating the type of work, qualified projects, etc. In the past, it was issued by the labor department, which was called "welder's certificate of boiler and pressure vessel", and there were qualified items. ): issued by the provincial special equipment safety supervision bureaus of the State Administration of Technical Supervision, Inspection and Quarantine. It shall be conducted by a qualified welding training unit after passing the basic theoretical knowledge training examination (generally 100 class hour). Skills training exams are conducted on a project-by-project basis, and each project usually takes about 20 working days. Inspection is divided into surface inspection, internal inspection and mechanical performance inspection, and certificates will be issued after all items are qualified. According to the Management Rules for Welder Examination of Boiler, Pressure Vessel and Pressure Pipeline, the welder's skills are divided into several items, each of which corresponds to a certain scope of application. Only in this way can the welding engineering quality of certified welders be guaranteed. Qualification certificate items are mainly classified according to different materials, specifications, welding methods and welding positions. The same materials and the same welding methods are listed item by item. For example, flat specimens are divided into horizontal position (1G), vertical position (3G), horizontal position (2G) and upward position (4G), and tubular specimens are divided into horizontal rotary welding (1G), horizontal fixed welding (2G), vertical fixed welding (5G) and 45-degree fixed welding (6G). Generally speaking, training in other events is not allowed until the plate training is qualified. \x0d\ Because the safe operation of special equipment for boilers, pressure vessels and pressure pipes is directly related to the safety of people's lives and property, the national regulatory authorities have long been strict with this certificate, and the qualification certificate for welding special equipment for boilers, pressure vessels and pressure pipes is recognized by the welding industry at present. Mainly because it is not affected by social factors such as length of service and age, but only based on the actual skills and technical level of welders. So at present, it is not only the boiler, pressure vessel and pressure pipeline special equipment industries that need this certificate, but also other industries that need welders to hold this certificate. Similar to this kind of certificate, there are certificates issued by standards formulated by other industries, such as power industry, shipbuilding industry and nuclear industry. , published by other standards. Due to the particularity of these industries, the requirements are also strict. For example, at least two plate-shaped specimens must be qualified before pipeline welding, and obstacle welding is added. \x0d\ III。 Metal welding and cutting safety operation certificate: issued by the national safety production supervision and management department. Mainly to carry out occupational safety education and simple practice to ensure the safety of welding personnel, but not to ensure the technical level of welding operation. The training time is 100 class hour. Under the supervision of the State Administration of Work Safety, it is assessed by qualified training and assessment units, and the State Administration of Work Safety issues certificates (IC cards). This certificate is for the safety of welders and is enforced by the state. Welders must have it, but it does not represent the welding technical level of welders. \x0d\ IV。 International welder qualification certificate: it is a welder qualification certificate issued by the European Welding Federation according to the international unified welder examination standard of EN287(ISO9606) (also handled by domestic institutions), and it is an important factor for enterprises to bid internationally or undertake business. The examination method is similar to the qualification certificate for welding special equipment of boilers, pressure vessels and pressure pipes in China. \x0d\ Source: China Welding Information Network Editor: Wolong Electric Yinchuan Transformer Liu Jianmin 20 10.5.
