Braze welding, brazing, and soldering are more of a bonding process than welding because the base material remains solid while a filler metal is melted into a joint.

Question

Quizplus · Accepted Answer

Braze welding, brazing, and soldering are all processes that involve the use of a filler metal that is melted into a joint to bond two pieces of material together. However, unlike welding, the base material does not melt and flow together. Instead, the filler metal forms a strong bond with the base material while both remain solid. Therefore, these processes are more accurately described as bonding processes rather than welding processes.
