- Nuclear Reactor Coolant Pipe Automatic (Mechanical) Welding Technology
- Nuclear reactor coolant pipes serve as connections between the primary components of the nuclear steam supply system (reactor, steam generator, reactor coolant pump). These pipes consist of 42-inch hot legs, 30-inch cold legs, and crossover legs. Automatic (mechanical) welding technology utilizes an automatic welding machine to perform outer and inner diameter welding, which leads to improvements in quality and a shortened construction time.

- Special Steel Welding Technology
-
Welding is a special process, with results that are influenced by process management or the welder's skills, and verifying the quality specified through product inspection or testing can be challenging. Consequently, a PQ test is conducted based on the requirements outlined in the code and standard. Welding construction conditions are analyzed and selected to ensure the soundness of on-site welded joints.
