  • This paper presents an EBW (Electron Beam Welding) technology for butt weld in stainless steel (00Cr17Ni14Mo2) tubes used in an electro-thermal component, which size is Φ22mm×2.5mm. By carrying out the EBW technology with a low current and a near-focusing manner, the inner convex of the weld is accurately controlled, the problem of external collapse is solved, and the One Side Welding Both Sides Formation technology is implemented. The specimen has passed all the tests required in Code RCC-M, including visual examination, liquid penetrate examination, X-ray inspection, tensile test, bending test, metallography detection, ferrite determination, and inter-granular corrosion test. Each quality above has reached the technological index grade I.
