magnets

I have a project that i would like to weld mild steel to a magnet.  I was wondering if this is possible without losing the magnetic field.  Also if you can weld it what is the best way I have an arc welder mig welder and a torch setup.  thanks for your help
Reply:Heat is basically going to destroy the magnet.  I suggest machining the mild steel component with a recess to hold the magnet and use a high strength epoxy to hold the magnet in place.Ron ShopFloorTalk Millermatic 350P, M-25, M-40 gunsDynasty 300DX, Coolmate 3, Crafter CS-310 TorchTrailblazer 302, 12RC, WC-2430A spoolgunSpectrum 2050Thermal Arc Plasma Welder PS-3000/WC-100B
Reply:I have done a lot of brazing on magnets in the past.  It works well with a 50% silver.  I'd imagine the tensile strength of the magnet is messed up a bit, but usually a magnet doesn't have to be very strong structurally.Welding on a magnet can be done, but it may mess up the magnetic affect as Shadetree mentioned above.  You could test it on something first if possible.  Also, you will notice that the magnetic pull will affect your arc, so the puddle won't want to go where you want it to, but it can be done.Proud to be a UNION worker.  Better pay, better benefits, better work environment.  UA Unions = working for the working class!!

Reply:Well thanks for your advice. I think I will just have to find a way to bolt the steel to the magnet. the magnet can not lose any of the magnetic strength and it has to be quite strong as the people that are going to use it are yard apes and will find a way to break it so it has to be bullet proof. thanks again for your help you guys are great!
Reply:We were stumped a while back at a place where I worked.  We enclosed a bunch of big magnets in a piece of broke s.s. in the shape of a c with a coverplate(for picking up steel on a street sweeper).  The molten metal would fly across the room about 50% of the time when we tried to mig it.  We had the most success from tig'n it while another guy held another magnet with the opposite polairty side close to what you were welding to keep things under control.  Occasionally the magnet would get too tough to hold in place and move too far away, meanwhile the weld would show it along with the nozzle melting away.  Talk about a pain in the rear.Common sense in an uncommon degree is what the world calls wisdom.
