To go along with the last post on welding myths and non-weldable materials, I also often get grudging calls from a designer who has been “forced” to add a weld to a design.
Customer: “How much do I have to overdesign this part for this weld?”
Me: “Why do you want to overdesign?”
Customer: “Well, the weld is going to weaken the part! I need to beef it up to compensate.”
