Remember what I say when the arm falls apart on a road course and tears up everything attached to it.
1. Our arm uses a custom alloy made at a foundry, which it is not 1018. Ours is much stronger than that. It is not a brittle tube.
2. MIG welding does have penetration. It is all about experience. Someone can cut one of our tubes in half that has been MIG welded and see that it does penetrate completely.
The same tubing and MIG welding has been used on drag cars that do wheelies. It has also been used on road race cars without any problems. We know it works, so that is why we can say it will have longevity.
