Bolt extraction on a Komatsu excavator. Constant battle on this one but we managed to get them all out. I used the tig process to weld buildup the end of the bolt above the surface. Then I used the suitcase welder with MiG to weld the washer to the bolt, and then the nut to the washer. This is my preferred method but as you see in this video it doesn’t always work first try. #tradesman #heavyequipment #mobilewelding #fabrication #craftsman #servicetruck #trades #metalfabricator #weldeverythingbe
