Trendy highway race, rally, and drag race automobiles, which might be based mostly on any new unibody chassis will see important torsional power enhancements by seam welding them. In any case, all newer automobiles are constructed from an incredible variety of sheetmetal elements which might be spot welded, or spot welded and chemically bonded, collectively to kind a whole physique construction. And whereas these strategies are designed to be robust and protected in an on-road setting, that isn’t the identical factor as a race setting. Particularly when you’re speaking about including way more stress from suspension and horsepower modifications.
So let’s imagine you’re taking a more recent automobile and stripping it down to only the shell so as to set up a cage, and so on. Irrespective of how when you take away each single half that may unbolt, you’re nonetheless going to have a lot of seam sealer, some bonding supplies, and so on that’s at each joint the place to separate items of steel come collectively. And whereas these supplies are tremendous for the road, repeated impacts, stresses, and cargo can weaken these joint. Maybe to not the purpose of failure, however actually to the purpose of inflicting undesirable flex throughout the chassis. If the chassis is flexing, as an alternative of the suspension, no quantity of suspension tuning will get your race automobile working completely.
On this video you’ll see the why and the way on seam welding a chassis. On this case, it’s a rally automobile, with a full cage, however welding all of the seams nonetheless offers main structural enhancements. Does that imply each automobile wants it carried out? No, but when you’ll take one aside to this stage anyway, there appears to be no purpose to not. Pun supposed.
