I am interested in teaching myself how to weld with gas. O2 Accetiline, not MIG gas.
I have a mig welder that I am sort of competent with. Is there benefit to welding with gas over MIG, or am I going to find that if I buy the tank set up, I'll never use it over MIG. Zach |

My welding friend was telling me that brazing can be made stronger than welding because of the capillary action that draws the filler between the welded pieces. He was saying that all decent bicylcle are put together this way for strength vs weight.
914's are brazed in some spots, like where the rear door well curves down and meets the top of the long, it is a high stress area that spot welds alone might not hold. |

I'm pretty sure it's really because a spot welder wasn't needed and most anybody could braze that area together. The old spot welders used to need to be clamped on both sides of the metals to work. Brazing was probably good enough. Have you ever seen the paint not stick to brass on unibody cars? |
