Scope

Main technical content: The main content is mainly divided into three parts: pre-welding preparation, welding process, and welding safety requirements. (1) Pre-welding preparation mainly includes requirements for the welding production environment of stainless steel welded pipes, production line operators, welding production equipment, the requirements for the welding joints during the process of rolling stainless steel strips into pipes, and the cleaning of welding grooves. (2) Welding process control mainly focuses on the welding parameters and process conditions of stainless steel welded pipes, such as DC dual TIG arc welding, pulse coordinated dual TIG arc welding, and TIG arc assisted MIG arc high-speed welding. It also includes the setting and requirements of composite arc states, the relative positions and forms of front and rear independent arcs, and weld formation, in order to meet the requirements of high-speed and low-energy welding production of stainless steel welded pipes of different specifications and materials. This part is the controlling element of efficient welding production of stainless steel welded pipes and the core content of this project standard. (3) Welding quality inspection specifies the inspection methods and indicator requirements for the production quality of stainless steel welded pipes, such as the appearance quality of the welds on the inner and outer surfaces of the steel pipes, and mechanical properties such as hardness and expansion performance. (4) Welding safety requirements mainly focus on the safety protection requirements for personnel and equipment during the welding production process.
