As they show in the example here, that was the cause of the problem. Someone welds on a mount for wider spring or a coil-over shock to increase the load carrying ability & they don't know enough to run equal beads on the opposite side (180 deg. off).

When you say to run a bead on the opposite side 180 degrees off, is that done even when you don't have anything to weld to the opposite side? For example I'm getting ready to weld on a simple perch to the bottom side of the housing, but I'm not planning on doing any welding on the topside, so does that mean it is going to warp? Just trying to figure it out before I weld. Thanks for the info. | | |

Get a piece of flat strap, maybe 1/4" X 4" X 24". Lay it on your welding table & somewhere near the middle run a good hot bead across the 4" dimension. Don't matter too much if you actually have another piece of iron to weld on or not, but if you do, even better. That means you'll run two beads, one on ea. side of your simulated perch. Now watch the 24" piece curl up towards the weld side.

Does that control warping or not? | | |

A continuous weld bead with a minimum of slag inclusion & good penetration ( means heat) is what most would agree gives the best strength.
We have machines available today so good that you can nearly lay a beautiful bead down on tissue paper. Due to that, we need even more skill to create a strong weld.
Practice pieces are still the best if you don't do a particular process enough to be sure of the results. Or, job it out to a pro.
