I started to post this on the tool steel thread, but thought it might do better here and not drift the other topic off into the wild blue yonder.
cr1, If I may digress from the subject of steel for a moment…. I would like to you or whoever is knowledgeable to discuss aluminum and aluminum repair.
While I can TIG or MIG the aluminum, it’s a real pain to drag all the equipment from the shop out to the interior of an RV, (Your choice of brand or type inserted here), For a long time it was the only way to do the job. Sometimes this meant tearing the rig apart so that I could keep from destroying other parts.
Lately I’ve been replacing some doors on an antique Avion pull camper, (like an Air Stream), and since Fleetwood doesn’t carry these doors, I have to build them from scratch. I have been trying out some aluminum brazing rod called Alumiweld, that does a very good job of filling and connecting the tubes and angles more easily than TIG or MIG.
As a test I tried joining a copper fitting to a piece aluminum and it seems strong, and survived my non-scientific strength test, (I beat on it with a 20 oz. ball pien hammer), and I couldn’t break the joint.
My question is, is there a long term detriment to using this stuff? As in corrosion problems, dissimilar metal reactions, strength problems for the base metal?
Since it flows at about 730°F, and works nicely with a Mapp or propane torch, the ease of use in an RV environment makes it almost ideal. I’ve even made overhead joints and vertical up joints with it.
Let’s hear from you guys!
