I designed this robot for a company I worked. I designed every component on this robot minus some of the cooling components for the receiver. All metal parts were designed with freecad and they manufactured via outsourced laser cutting and bending and the cylindrical parts were made in house with a cnc lathe. The motor driven part is made out of a combination of cold rolled steel, aluminum, and stainless. The receiver is made out of primarily titanium because of its thermal properties and being able to keep the bearings cool. The cooling system is an old window air conditioner with the condenser submerged in a ethylene glycol water mixture which is pumped up to the head; this keeps it cool during and between welding. This is needed because the bearings have a certain temperature rating that would be greatly exceeded. The schematic and pcb were designed in kicad. The program was written with arduino. The program takes input from the button array and outputs it to the stepper motors and tot the welder itself turning it off and on.
