Why weld joints are stronger than the base material itself?

[QUOTE="jrmichler, post: 6200002, member: 638574"] A typical fillet weld on thin wall tubing will have cross sectional area much larger than the tube wall thickness. The weld material can have lower yield strength than the tubing, but be stronger because of the larger area. I once welded up a recumbent bicycle frame from 4130 tube. I used a torch and coat hangers for filler. After 3000 miles of use and abuse, there were no cracks. I even stress tested it by riding down the steps of the local public library. 4130 is an alloy specifically designed for easy welding and for high fatigue strength. It was originally designed for steel tube aircraft fuselage use. [/QUOTE]
