cleaning threads after flux core welding

admin

Hello. I use a HF flux core welder to tack weld with.                                                              I thought I had done a decent job with covering a part that has a thread on it  but i got a few dots of splatter so that i can screw my part together so well.   Is there a best way to clean these threads?
Reply:I'd try using a bench girder with a wire wheel/some kind of wire brush on it first. I now put anti-seize on all threaded parts prior to welding now thanks to the guys on here .-Pat

Reply:If it's male thread and you don't have a die for it, a triangle file will usually clean it up acceptably.
Reply:One unorthodox solution:Dip the threads you want 'clean' in oil before welding and generally they stay clean. I know its messy, and a lot of heat input would cause smoke & maybe fire, but it works. Use your better judgement here. -corne-Last edited by cornemuse; 12-20-2012 at 10:36 AM.Reason: spelling!!
Reply:I use tap & die to clean up after also but I try to use tape before.  I have used masking or duct tape usually whatever is close.  Aluminum foil or foil tape for ductwork too.Miller XMT 304 cc/cvMiller 12RC w/ 15ft Tweco #4 GunMiller 30A SpoolgunCustom Thermal Arc TA 10/270 Generator "Thermal Star"Smith oxy/acet-propane with weld, cut & rosebud tipsAnd of course grinders, chop saws, hand tools

Reply:Flux core.  Feel the pain too,When putting casters on, threaded post style, I weld in thread couplers for mounting.  To keep the threads clean I thread in a sacrificial screw to plug the hole. Can you do a similar thing and thread some nuts on as covers for external threads?

Reply:Spray with anti spatter and use a thread file
Reply:Im working constantly with/near precision machined threads and I can say that the only thing that does the job properly is covering them up first. I have access to and generally use a thin (.020") brass sheet wrapped arounding threading and held in place with a hoseclamp. alternately a piece of pipe cut and used as a sleeve works if the fit is snug. antisplatter and thread files work acceptably if the tolerances are relaxed on the end result. they arent an option for me unfortunately.
