Pre-processed (welded pipe fittings)
"Kaizaki" refers to the butt joint shape of the butt-welded parts, and its design and processing accuracy greatly influence the quality after welding.
"Bevel" (kaisaki), also known as "groove," refers to the gap created between two base materials when they are joined together, which is necessary to ensure that the welded joint has the same quality and strength as the base materials. At the same time, a design and machining precision that minimizes the occurrence of welding defects is required. For example, increasing the bevel angle results in a larger amount of welding material, which can lead to increased welding labor and affect the mechanical properties and shape distortion near the weld due to the heat input on the base material. Conversely, if the bevel angle is narrowed, it can lead to decreased workability, poor penetration, and the possibility of defects such as slag inclusions that cannot be detected from the surface, increasing the likelihood of welding defects. Therefore, the shape and processing of the bevel are crucial, and they are designed to achieve optimal shapes and dimensions considering factors such as the properties and pressure of the fluid, material, thickness, diameter, and welding environment.
