Spinweld assisted with friction weld trials and mechanical testing /characterization of welded parts for the repair design/plug for a cast bronze alloy.
This part was designed between Spinweld and MetalTek to fit requirements for friction welding machinery with a cup-cone casting repair configuration.
Weld trial samples of plug and hole configuration were successful in the repair of cast aluminum-bronze parts. The trials used a cup and cone configuration. 3 samples of the plug and hole were successful! There was a solid fusion through the weld, although sections at the bottom of the weld displayed a lack of fusion. Hardness was increased across the welded material, and the weld maintained tensile strength as compared to the cast material. This was apparent as the parts were cut in half and buffed to show the cross-section reveals the flash flow. A macro etch test revealed that the weld displayed good fusion.
