There are really two brazing processes to consider, brazing and braze welding. Braze welding is similar to welding in joint design, but uses a brazing filler metal. It is relatively easy to do if you know how to gas weld. You can pretty much use the pre-coated filler metal or bare filler metal that is dipped in flux while hot similar to the way you would use normal filler metal. The main difference between braze welding and welding is that the base metal is not melted in braze welding. Braze welding can be used to make groove welds or fillet welds just like welding. Brazing uses the same low melting temperature type filler metals that braze welding does, but the joints are designed to use capillary action to draw the filler metal into the joint. Thus joint design and fitup is important. Lap joints are probably the most common, but scarf joints or other designs are possible too.
