November 24, 201510 yr At the steel yard today, the owner threw a 2ft X 3 foot piece of A/R (abrasive resistant steel plate) in my truck. You got to love free!!! Can this be welded to a mild steel base to make dies for the PH and hyd press? If so, can you share any thoughts on pre/post heat etc? or other uses. Funny, I didn't know that I need this piece of steel until I got it. Now I've got to put it to good use. What a terrible responsibility.....
November 24, 201510 yr Is it marked at all? If not, try looking up specs for AR400, or AR500 as they are fairly common alloys. They are not a just weld it with anything type of alloy. It can be done, but with the proper rods, and technique.
November 24, 201510 yr IF NOT welded right !! It will snap the welds !!! & pop off been there done that !! I built a PH base / box welded a AR bottom plate to it with good rod choice I thought LOL 110/18 as it cooled you could watch it snap apart lost alot of time on that one -- redo was another base plate a week later I would not use it for die's getting the weld right & safe is a pain !! It can be done though careful pre & post heat is a must ! AR is great for a welding table top though Steve's Welding & Fab PS that ar plate is still on the ground 8 years later Top table plate is still a good Idea !
December 8, 201510 yr Big time sneaky lurker here. Regarding Hardox 450 /500 and AR 450 Twice a year I have a job welding in a wear plate in to a "grate". I use 1/16 TM 771 wire shielded with co2. Lincoln sells the same thing only better called Ultra core 712C. If its cold out, and it almost is all the time,, I pre heat as hot as i can get this big lump with a 2'' propane torch and weld . The welds (every 4inches) keeps the whole thing sort of warm. Also after its welded I lay down a pass of hard face wire over the weld to protect it . I have never had one cut loose '' on the job''. BUT, as I weld temporary hoisting loops on the wear plate I have had them break off without warning. I believe its because the weld was small and cold.
