This video shows the details of how a high end aluminum bicycle frame is fabricated and welded.
Tig welding aluminum bicycle frame.
Bicycle fabrication supply keeps in stock inweld tig welding alloys for steel stainless and aluminum.
Another mission powder coated blue.
Some other aluminum alloys for example 7075 and 2014 stronger than both alloys 6061 and 7005 but they are not enough suitable for the manufacture of bicycle frames because they are almost impossible to weld at least usually argon arc welding.
Alloy 6061 and alloy 7005.
Tig welded joints are the most common type today found on lots of bikes and lots of styles.
When you re getting started with bicycle framebuilding you have different options for how you want to join the tubes of the bike frame together.
You can get more information about welding and metalworking.
What you re seeing is raw steel tubing with a clear gloss powder coat.
Mike uses a miller dynasty 280dx for tig welding aluminum bike frames and he also has the expansion pack which allows for independent amplitude settings.
That is a pretty cool feature that has benefits for tig welding aluminum.
Inweld has been providing the welding and fabrication industry with quality products since 1970.
Above is a mission frame made of 4130 chromoly steel that s been tig tungsten inert gas welded.
Aluminum bicycle frames are made mainly of aluminum alloys.
So he can set amperage different on each side of the alternating current cycle.
