Advancements in Welding for molybdenum sheet: Current and Future Trends

Molybdenum, a transition metal with unique properties, is finding increasing application in various industries due to its high melting point, corrosion resistance, and high tensile strength. However, welding molybdenum sheet can be challenging, as it requires special considerations and techniques to ensure quality joints. In this article, we will explore the advancements in welding for molybdenum sheet, both current and future trends.

Current Trends in Welding molybdenum sheet

  1. Preparation of the Joint: Preparation of the joint area is crucial for successful welding of molybdenum sheet. Cleanliness is essential to remove any impurities or oxides that may affect the weld.Common surface treatment methods include mechanical cleaning, chemical cleaning, and electrochemical cleaning. Appropriate surface treatment ensures that the joint area is free of contaminants and ready for welding.

  2. Welding Processes: There are several welding processes that can be used for molybdenum sheet, including arc welding, laser welding, and friction welding. Arc welding is a widely used process due to its versatility and cost-effectiveness. However, laser welding and friction welding are becoming more popular due to their ability to produce high-quality welds with minimal distortion and residual stress.

  3. Post-weld Heat Treatment: Post-weld heat treatment is essential to relieve residual stress and improve the mechanical properties of the weld. Heat treatment typically involves heating the weld to a temperature just below the melting point of molybdenum sheet slowly cooling it down. This process helps to optimize the microstructure and improve the mechanical properties of the weld.

Future Trends in Welding molybdenum sheet
