To answer question ..The term "Brazing" is a process of joining two pieces of material using a filler material such as brass but not exclusive to brass. Brazing and Braze welding are terms that are often used interchangeably and the equipment required to do the job is essentially the same even though the process is slightly different. In the article it clearly states "Bronze" filler. The whole point of the post is to inform people that there are processes available to them that will allow them to repair damaged castings. Here is the actual definition of the word Brazing.

"Brazing is a metal-joining process whereby a filler metal is heated above melting point and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then cooled to join the workpieces together.[1] It is similar to soldering, except the temperatures used to melt the filler metal are higher for brazing."

Below is a link that might add some clarity to the issue.
