Fig.
14-3. This is a well-deposited layer of bronze. Note the even ripple,
uniform
width. The black spots are melted flux.
Fig.
14-1. Examples of good and bad starts in braze welding. For A,
conditions
were right. At B, the plate was too hot, so that the bronze ran to
the
edge of puddle, with an oxidized area in center. At C, the plate was too
cold,
so the bronze built up instead of spreading well. At D, the plate
surface
had not been properly cleaned.
Fig.
14-2. A poor braze weld which illustrates several faults. At A, the rod
was dipped too far ahead of the puddle.
At B, the bronze was allowed to drip from
the end of the rod, forming globules. At C, the base metal was, too hot,
so the bronze spread out too much and
ran ahead too far.
