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 analysis!
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 analysis.
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!
