leaf spring yoke welding

admin

HiI'm in the process of building a 6' x 10' utility trailer with a 3500lb axle. The yokes that get welded onto the frame are clamped up but I have a question. A while ago I received some "advice" from a guy that said when welding the yoke it's best to orient the welds parallel to the frame (which is a 2" x 3" x 1/8" wall tube) rather than run the weld along the yoke perpendicular to the frame. I understand that a poor weld, hot or cold, could cause a weak area but his suggestion was that a weld across the frame holding the leaf spring yoke on in this fashion would inevitably fail. Thoughts?

Reply:That advice is correct. Depending on it's duty, cracks will begin at the welds stops along the side of the spring perch anyway, but it takes a long time. If you weld across the underside of frame it happens quicker.If you take a 1/4" rod about 4' long and quickly move it up and down you can see how that frame flexes while it is in use. If you notch the rod on the top or bottom near the center it will fail much faster, and it will fail at the notch.Matt
