In the face feed method of silver brazing, into what area is the filler metal fed?

In the face feed method of silver brazing, the filler metal is introduced into the joint area where the two base metals come together. This technique is specifically designed to ensure optimal flow of the filler metal, allowing it to move into the joint as it melts and is drawn into the gap between the parts being joined.

Feeding the filler metal into the joint area helps to create a strong, uniform bond as the molten filler flows and fills any gaps or imperfections in the joint. This method relies on capillary action, which draws the molten filler into the narrow space created by the two pieces that are being brazed, thus ensuring a good bond and achieving the properties desired in a brazed joint.

Choosing the joint area for the feeding of the filler material is crucial for achieving a reliable connection, as filling this specific area allows for the strongest metallurgical joint and optimal performance of the final assembly.
