Welding

TAM Ceramics has over 80 years of experience manufacturing ceramic welding powders and flux materials and a patented process to encapsulate particles to prevent moisture pick-up.

TAM offers dozens of milling options to address particle size and shape requirements and ensure proper flow characteristics. Our ceramic raw material expertise with unique processing tools help us design powders with optimal size, chemistry, and cost.

With a unique depth in ceramic engineers, experienced operators and dedicated managers, TAM maintains a large facility with big capabilities while operating as a small, private, management-owned company.

Products used in welding (other ceramic materials and processing options are available):

• Sodium Titanate
• Potassium Titanate
• Rutile (TiO₂)
• Zircon
• Zirconia

Welding Science

• Sodium Titanate and Potassium Titanate are frequently used in cored welding rod formulations at ~25%wt
• The Titanate (TiO₂) acts as a slag former
• Na₂O and K₂O are both arc stabilizers.  Used together, the sodium and potassium provide good slag flow and sustained arc stability, resulting in cleaner welds and better overall metallurgical properties.  The disadvantages are that both are hygroscopic, and tend to absorb significant amounts of moisture from the air.  This increased hydrogen pick-up leads to brittleness in the finished weld and can also affect the free-flowing properties of the powder when filling cored welding wire and rods.

TAM Ceramics has invented a way to seal these powders in an impervious glassy layer to form a vapor barrier, providing the industry’s best free-flowing, moisture-resistant Titanate powders available.
