Can I Weld or Solder 3D Printed Steel Parts Together?

Yes, you can. TIG (tungsten inert gas) welding with silicon bronze filler can be used to weld 3D printed steel parts together. If a strong bond isn’t required, you can also silver solder steel parts together with a torch. This is typically done for smaller applications. Additionally, using solder will require flux or a flux paint to make sure the parts bond.
