What is the term used when a non-ferrous filler metal is applied but not distributed by capillary action?

The term "braze welding" refers to a process in which a non-ferrous filler metal is applied to join pieces of metal without melting the base metals. This method involves applying the filler metal in conjunction with sufficient heat to establish a bond between the workpieces while leaving the metal parts intact and unaltered.

In this specific process, the filler does not flow into the joint via capillary action, which differentiates it from traditional brazing, where the filler material is typically drawn into the joint space through capillary action due to its lower melting point. Braze welding uses a different approach, resulting in a thicker bond, and can also involve some melting of the base metals, particularly at the edges, which is not the case in standard brazing.

The other options each describe different processes that do not fit the requirements of the question. Welding generally refers to processes that melt the base materials, while brazing involves the capillary action that the question specifies is absent in this context. Fluxing is a preparatory step used to clean metal surfaces and facilitate bonding but is not a type of metal joining process itself.
