Introduction

Electron beam welding is a welding process that uses electron beams as a heat source. It is used in various industries such as aviation, aerospace, weapons, automobiles, and machinery. Has been widely used. Industrial CT has been used for non-destructive testing of electron beam weld quality for more than 20 years, ensuring the quality of electron beam welding parts. It plays an important role in quantity and reliability. This standard is based on the experience of many years of experience in CT inspection of electron beam weld industry. Fixed. Weld nondestructive testing electron beam welding joint Industrial computer tomography (CT) detection method

1 Scope
