Hello , I have a case study in my graduate program and I have to tell that which welding process is used to weld fire extinguishers. This will be of great help.
I would contact a manufacturer of fire extinguishers and ask them. Or maybe learn what materials are used in the construction of fire extinguishers and how they are joined.
We don't do homework here.
You should perform your own "case study". That's the point of school.
We don't. There are plenty of good homework sites. Try Physicsforum.com or Scienceforums.net. Both will require you to show some effort before providing assistance.
