Joint Clearance
The brazing gap width is the distance between the parts to be joined. It must be maintained precisely to ensure optimal filling and capillary forces. Gaps that are too wide result in incomplete filling.
Physicochemical Mechanism of Action
The brazing gap width influences the capillary forces that draw the liquid filler metal onto the surfaces. An excessive gap can interrupt these forces and lead to incomplete filling of the gap.
Metallurgical Relevance & Welding Risks
A too small brazing gap width can cause overfilling and distortion of the components. A too large gap prevents complete filling, resulting in missing joints and weak spots in the structure.
Workshop Practice & Instructions
The brazing gap width should be adhered to precisely according to the design drawings. With a gap width of 0.5 mm, filling with a filler metal such as silver is well possible. Regularly check the actual gap width and correct if necessary.
