How are bikes welded together?
A filler metal (like brass or silver) is heated just above its melting point and distributed over two adjacent tubes. As the filler metal cools it hardens and forms a joint connecting the metals. Brazing uses a filler metal with a melting temperature lower than the frame material.
What type of welding is used for bike frames?
Of all the welding process available, the gas metal arc welding (GMA) and gas tungsten arc (GTA) welding processes are best suited for welding tubing of a motorcycle frame. Many frames are GMA welded, and GMAW is the easiest process in which to become proficient – Fig. 1.
Can you weld a bike frame back together?
Aluminum can’t be re-welded to its original strength like steel can. If you weld it, it will be barely any stronger than not, and you run the risk of a major breakage. I would just replace the frame rather than attempt to repair it.
Is welding better than brazing?
Brazing soundly beats welding when joining dissimilar metals. As long as the filler material is metallurgically compatible with both base metals and melts at a lower temperature, brazing can create strong joints with barely any alteration of the base metals’ properties.
Can you MIG weld a bicycle frame?
While we won’t say you can’t MIG or Stick weld a bike frame together, most bicycles use a combination of brazing and TIG welding for their construction. Why TIG? Because welding a bicycle frame requires a lot of control over your heat, a task that’s more easily accomplished with a TIG welding pedal.
What is TIG welding in bike frames?
What is TIG welding? TIG welding (Tungsten Inert Gas), also known as Gas Tungsten Arc Welding (GTAW), was first developed by the aerospace industry in the 1940s. We chose this technique for the high quality, clean welds it produces. And the exceptional precision it allows in hard to reach places.
How long does it take to weld a bike frame?
But half an hour is about right. One of the fastest and easiest parts of building the frame, really. If you were working with thicker/cheaper material, spent all day every day doing it, and had a really nice welding fixture, I imagine 15 minutes or less would be easily doable.
Can I stick weld a bicycle frame?

What is the difference between brazing and TIG welding?
Tig welding applies higher heat to the materials, but on a small area, whereas brazing applies a lower heat but in a bigger area. Both can lead to overheating, which makes the material more brittle and prone to cracking.
Can you patch a frame?
If you’re willing to do the work yourself, you can repair a rusty truck frame for a small fraction of the cost. While it will require a great deal of time and elbow grease, it’s actually not all that complicated of a process.
