Zirconium tube welding process
1. Zirconium tube selection
Selecting the right zirconium tube material is the first step to successful welding. The appropriate process material should be selected according to the use environment, the type of metal material, the organizational structure, the physical properties, the chemical properties, etc.
2. Zirconium tube surface treatment
Before welding the zirconium tube, the pipe surface must be properly treated. Surface treatment includes removing the oxide layer on the surface of the zirconium tube to reduce the inclusion of impurities and oxides. At the same time, the surface of the zirconium tube should be kept dry and clean.
3. Zirconium tube overlap method
Common overlap methods include protruding overlap, flat overlap, slight gap, etc.
4. Zirconium tube filling material
The selection and use of filling materials directly affect the welding quality. Welding rods with the same physical properties as the zirconium tube, such as the coefficient of expansion and melting point, should be selected.
5. Zirconium tube welding process
Zirconium tube welding is generally divided into several steps, such as preheating, heat treatment, filling, welding and post-heat treatment.
