What is the impact of inadequate temperature control during brazing?

Inadequate temperature control during brazing can significantly affect the melting of the filler material used in the process. Brazing requires precise temperature management to ensure that the filler metal reaches its melting point without excessively heating the base metals. If the temperature is insufficient, the filler material may not melt properly, leading to insufficient wetting of the joint surfaces, which is essential for a robust bond. This can result in weak joints that fail to meet structural integrity requirements.

When the filler does not melt adequately, it can create a poorly defined joint, reducing its overall strength and durability. Proper temperature control is crucial to achieving the necessary melting and flow of the filler material, ensuring that it effectively fills the gap between the workpieces and forms a solid bond upon cooling.
