    • In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.
    • We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).
    • Annual membership also comes with two BiplaneForum.com decals.

Please first let me thank you all for a very informative and entertaining forum!
My question is rather simple- years ago, when learning gas welding, the fellow who taught me told me that when TIG welding 4130 tubing, you needed to go back and normalize the weld with an oxyacetylene torch. Is this so? I have a TIG machine now, and would like to use it on my project if I can learn the correct method.
Many Thanks!
