Does it need heat treatment after welding? Cheap 6061 frames which haven't been retreated after welding tend to fail in the area affected by the heat of welding.

According to the article they achieved about 70% strength in the HAZ without post-weld heat treat, and full strength after heat treat. For comparison, a bad 6061 weld might be as low as 20% strength without post-weld heat treat, but it might recover to over 50% if it comes from China by ship :)
