Cleaning flux from hard to get areas

admin

Been lurking for a few weeks. You guys sure are a huge wealth of information. Got one question I havn't seen an answer for yet in my travels.I've got some flux drifting into a hard to clean area (nice 90 degree corner under a lip right next to the weld area). I can't use GMAW. I need to clean that flux out of there, but I cant reach it with any combination of grinder, wire wheel, or wire brush. Is there something I can spray on, or soak it in, or something that'll remove it?--Chris

Reply:"Flux drifting in"... Do you mean fume deposits? Or weld slag? Two different animals.For fume deposits, even Q-tips will get it out. Wipe right off dry, and a spraydown with water and a little detergent will get the rest. Compressed air to dry.If it is slag, say because the weld is going into the corner, then you can try a chisel (a V or a cape point) if you can get a good angle; sharpen the peck end on a slag hammer to a slight chisel point and drag/scrape it into the corner; sand or glassbead blast (a pencil blast gun is a great tool for this... just be sure to meet the requirements for dust collection and breathing air filtering, or you will rapidly find yourself choking to death-- literally); If there is a straight shot, a small carbide burr (or stone point) on a long shank in the die grinder works.
Reply:Yeah, fume deposits. White powdery looking stuff. I didn't realize it brushed off so easy. Time to go poking around at the hardware store for odd shaped cleaning things I guess...
Reply:I have a small siphon style sandblaster that I keep.   If I run into Flux in a tight spot it will usually clean it right out.  Just watch your eyes and lungs with the sand.  Fume deposits will usually just wipe off.~JacksonI'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:A needle gun works wonders. I have one on the truck and it will take damn near anything off.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:My trick that I use at work.  SCREWDRIVER.  Simple, cheap, very effective.  I carry an assortment in my welding bag.  I sharpen them or modify them with the grinder to make them work how I need them.  Like a dentist with all my "picks".

Reply:My question would be...if you were able to weld the area how is it that you cannot get at it to remove flux?
