Molybdenum Rod Connection Techniques: Methods and Choices

When discussing the connection technology of molybdenum rods, we need to consider different methods and choices, which usually depend on specific application requirements, material characteristics, and process requirements. The following are some common molybdenum rod connection technologies and their brief introductions:
1.Welding connection:
Molybdenum rods can be connected through welding technology. Due to the high melting point (2617 ° C) and excellent thermal properties of molybdenum, the welding process requires special equipment and process control.
Common welding methods include argon arc welding, electron beam welding, and laser welding. These methods can provide high-quality welded joints, suitable for applications with high requirements for connection strength.
2.Mechanical connection:
Mechanical connection methods such as bolt connection, pin connection, or fixture connection are also effective choices for molybdenum rod connection.
These methods do not require complex heating processes, making them suitable for applications that are not suitable for welding or require quick installation.
It should be noted that mechanical connections may not provide the same connection strength as welding, so evaluation needs to be based on specific needs

3.Brazing connection:
Brazing is a method of connecting two or more metal components together using brazing material with a melting point lower than the base metal.
For molybdenum rod connections, brazing can provide good sealing and conductivity, making it suitable for applications that require electrical performance.
Brazing connection requires controlling the brazing temperature and time to ensure that the brazing material is fully melted and the joint gap is filled.
4.Diffusion connection:
Diffusion bonding is a method of bonding two material surfaces through atomic diffusion at high temperatures.
For molybdenum rod connections, diffusion bonding can provide connection joints that are close to the strength of the base material, suitable for high temperature and high pressure environments.
Diffusion bonding requires a longer bonding time and a high-temperature environment, so the cost may be higher.
When choosing molybdenum rod connection technology, the following factors need to be considered:
Connection strength: Determine the required connection strength based on application requirements.
Working environment: Consider the temperature, pressure, corrosiveness, and other environmental conditions that the connectors will be exposed to.
Cost: Evaluate the cost-effectiveness of different connection technologies.
Processability: Consider the processing difficulty and feasibility of the connection technology.
In summary, the selection of molybdenum rod connection technology should be based on specific application requirements and material characteristics. In practical applications, other factors may need to be considered, such as the size, shape, and tolerance of the connectors. Therefore, it is recommended to consult professional engineers or material experts when choosing connection technologies to obtain more accurate advice.
