In furnace brazing, the filler metal is heated in a furnace to its melting temperature and then conveyed to the joint by means of a ceramic rod or another transfer device. Since the highest temperature is focused at the end of the inner cone, if oxygen/acetylene is being used for brazing, the torch must be kept in motion to evenly distribute heat. I can see how you could get those micro inclusions if a welder isn't careful. Welding produces the strongest joints since the metals are physically fused together. Dude i think the whole tig brazing thing was set off when some clown put up a picture of a motorcycle frame and suggested it was tig brazing (it wasn't it was meant as a tongue in cheek post but gained an entire life of its own) Dave bohm even had an entire Meme mocking ithowever time moved on a lot of new guys joined in in framebuilding land and didn't get the joke. Note that there is also an O-ring in the assembly to prevent shielding gas from escaping out the backside of the torch, and direct it into the welding cup instead.
