Discusse the laser welding process and its personnel international certification process

aiming to ensure welding quality and meet the requirements of the international quality standard system. It first introduces the basic principles and classification of laser welding technology

and elaborates on the process of laser welding procedure qualification

including welding joint design

preparation of preliminary welding procedure specifications (pWPS)

post-weld inspection (non-destructive testing and destructive testing)

and approval scope. Then

it analyzes the international certification process for laser welding welders and operators

including examination elements

approval scope

inspection methods

and certificate validity. The results show that laser welding technology is widely used in industries such as automobile manufacturing

machinery manufacturing

and metal products

and has advantages such as high efficiency

environmental protection

and high precision. International certification can effectively ensure welding quality and enhance the ability of enterprises to participate in international market competition. With the continuous development of laser technology and the expansion of application fields

laser welding technology will play a greater role and be further improved. Enterprises should pay attention to the international certification of laser welding processes and personnel to adapt to the development trends of the future manufacturing industry.
