1, the welder's grade is through study and examination, and has passed the professional college. At present, many training points (schools) think that the higher the welder's training level (bureau level, municipal level, ministerial level and provincial level), the more difficult it is to obtain the certificate.
2, you must first have a primary certificate (operation certificate) as long as you can operate.
3. After two years, read (take an examination of) the intermediate certificate to learn welding theory and welding skills.
4. After two or three years, read (take an examination of) the advanced certificate to learn the welding principle.
5. Re-study (test) after two or three years. Technicians should learn to weld, learn to invent, and actually write papers. Experts will appraise your study (thesis) and practical operation.
Welders must undergo professional training and pass the examination before taking up their posts. Non-welders are forbidden to engage in welding operations. Wear safety protection articles such as welding overalls, insulating shoes, welding gloves and protective masks during operation. Fasten your seat belt when working at height.
