Best Welding and Manufacturing Practices
The invar rod is ductile and weldable using:
- TIG (Tungsten Inert Gas) welding
- MIG (Metal Inert Gas) welding
- Electron beam welding
Forming techniques include cold working and machining, with properties similar to austenitic stainless steel. Annealing may be required post-fabrication to relieve stresses.
