  Process:

  This alloy can be machined using traditional iron based material processing methods. Water coolant is used during high-speed machining. The material shrinks during processing, and attention should be paid to ensuring dimensional accuracy with machining shrinkage allowance.

  
  

  Weld:

  The Monel 400 has good welding performance and can use TIG and MIG methods. Monel body or EniCu-7 welding wire and electrode can be used; Alternatively, manual arc welding and submerged arc welding; Can be welded with carbon steel and low alloy steel.
