.........is too red?
(Firstly hello to everyone from a newbie).
Simple question (or perhaps not?) - how red is it acceptable for the steel to turn during brazing before losing integrity?
I've just started learning to braze (we're talking pre kindergarten here) and want to be sure I'm on the right track before I even consider moving on to building a full frame, and I've come accross some conflicting 'opinions' on the subject.
I'm aware that heat spots where the steel starts pitting are clearly undesirable, but aside from that I'm unsure as to whether I'm overheating. Is there a set 'rule'? If I can see red through my goggles have I taken it too far? Should the silver flow without direct heat from the torch? (Very basic stuff here as you can see)
Any help greatly appreciated.
(If anyone knows of a comprehensive brazing guide to be found onlide that'd be great)
