'How-to' Welding Class: Destructive Test of Final Gas Weld
This HD video follows the practice welding cube
as it is subjected to the force of a 20-ton press. (The 16-gauge sheet metal collapses below the 20-ton maximum
force.) Watch the results as we subject the gas welded "cube project" to destructive
(If you have enough bandwidth, the video is viewable in

Everyone wants 'stack of dimes'
aluminum TIG welds and steel welds that appear attractive. The real test of a weld, however, is its
integrity and the degree of metal fusion. While this includes visible results like a proper weld crown and
penetration, welds in many fields must also be subject to X-rays, sonic tests or destructive
As you will see in the HD video, the first step in
the destructive test took the metal to its deformation limit. Above view is the deep impression made by
the press and a round block spacer. At this stage, we will subject our project cube to a greater force:
sandwiching the piece between two matching press plates and applying full load!

welding and brazing articles and HD videos throughout the 'How-to: Welding Class'
