[PSUBS-MAILIST] overlay welding

Tue Nov 15 08:27:35 EST 2016

Hi Hames,Thanks' that is interesting, I remember now that the K subs require that on their pods.   I have to use wire feed, but I am less afraid now.  I gave my stick welder to my brother.Hank

 Hank,When I made the battery pod ends, I initially clad them.  I used 309mo (which is what is specified for the dissimilar joints so I already had some).  It machined fine and according to the spec, has good corrosion resistance. In the end, I didn't go with that method as I couldn't get it thick enough and kept machining too much off so I gave up and did it a different way. might be worth a look?  http://www.magmaweld.com/ei_309mol_stainless_steel_stick_electrode.htmlJames

Hi Hank,303 SS is easiest to machine.  Better than 304.  However there is the corrosion issue.Google it for properties.  Hugh From: Personal_Submersibles [mailto:personal_submersibles- bounces at psubs.org] On Behalf Of hank pronk via Personal_Submersibles
