Sep 01, 2007 WOW!! I just took a look! Thanks for all the replies!! All very helpfull! I should have been more specific. When I repair older alluminum castings, some times I have to grind out the weld and do it again, do to all the old oil and crap in the original casting, for me the grinding out never goes well, the stones load or just don't cut well, then I have to clean it all up again and weld again.

I kiss the top with a 24 or 36 G 3M ( orange ) disk - aways use grinding lube. Then I switch to Norton Flap disc's - still usin lube. If you want to go far with the blend - 3rd step is 3M Imperial Hookit disc's on a DA or hand pad. It's messy - but works great.
Mar 14, 2011 Welders and fabricators perform grinding on aluminum for many reasons, whether it is preweld surface preparation or postweld bead finishing or removal. Compared with other metals, aluminum has a much lower melting temperature, so it melts easily.

Aug 11, 2005 Repairing a thin aluminum boat hull does not require expensive custom carbide burrs (that will load up anyway) A quality 3 inch 80 grit aluminum oxide disc and a 18,000 rpm angle die grinder will be the optimum tool for surface prep and weld blending on aluminum sheet. X-ray quality welds are produced by the thousands on a daily basis using ...

Longer aluminum chips coat the abrasive, which prevents the grain from doing its job. For best results with flap discs, use light and even pressure to optimize the grinding process and reduce loading. Using a T29 (conical) disc at a 15-degree angle provides high ...

May 27, 2005 Fatfrank, Bit of a jumbled sentence there, but still clear enough to make out. 1. Weld up an example of a joint you wish to test this theory out on. 2. Once you have this example, cut it in half to give you two equal examples. 3. Leave one as welded and grind the other in order to give you an example of both.
Jul 20, 2016 If you have dirty 6061, you have two choices: a) Get cleaner aluminum or b) Clean the aluminum in Bio Circle Alustar 100. We use a tank with an agitator and heater. We hang the parts in the bath for a couple of hours. This also works well
Jul 27, 2016 On thin aluminum, I'll often grind through like this, then back up the gap with a piece of clean steel or stainless when welding, so I don't risk drip-out from getting too hot too fast. ... I've seen a lot of leaky aluminum mig welds come into the shop in the past. Tig is a much better process when you need something sealed up tight ...

Just stop the pedal and hold is there for 5 seconds then left off and hold the torch ...
Oct 11, 2018 The answer is no. While 5356 is stronger than 4043, they're both stronger than the weakest area of the heat-affected zone (HAZ) in 6061-T6 butt welds. These butt welds fail in the HAZ—not in the weld metal—and the strength doesn't change, regardless of the filler metal. This isn't the same with lap or fillet welds.

Dec 03, 2021 TIG Tungsten Grinding - Miller Welding Discussion Forums. May 02, 2012 TIG Tungsten Grinding It does depend on how your grinding it, a stone with a fine grit would be better, but try to avoid grinding it with the side of the tungsten towards the stone as the grind marks will cause the arc to be more unstable and sort of spiral off the tungsten where as if it's

Remote control technology provides welding operators with the ability to set welding parameters at the joint, increasing safety by reducing trips to and from the power source, and increasing arc-on time for greater productivity. This technology also helps improve quality by eliminating the need to settle for less-than-optimal settings.
Jul 20, 2016 Do not grind carbon steel in the same end of the building that you are welding aluminum. It WILL contaminate the aluminum and create nightmares with the finished welds. Ensure that your MIG and TIG fill are in sealed containers. Use only good quality fill, not fill purchased from companies that buy up excess and respool it for resale.
Apr 30, 2018 Mash that pedal to the floor and reduce the input so it just doesn't run away from you but stays hot enough to get a good 'fluid' puddle and dip that rod a lot. Bye, Arno.

Sep 12, 2011 (2) WELDING ALUMINUM IN THE WRONG POLARITY/ADJUSTING BALANCE You should generally always TIG-weld aluminum with alternating current (AC). Welding with direct current (DC) will make it difficult to eliminate the aluminum oxide layer. This oxide layer can mix with the filler metal, contributing to contamination.
My machine is set to 25.9 V and 378 wirespeed, i think im using 316L .035" wire. I looked on the miller website for machine settings and it tells me to use 1/16 wire for 1/2" aluminium but we dont have anything but 0.035 wire and maybe some 0.045. That is a 1" square bar and 1/2" aluminum plate. Any advice would be grestly appreciated! TIA
Sep 08, 2021 Rochester, Minn.-based Paul Cameron, a certified welding inspector (CWI) and nondestructive testing tech at Braun Intertec Corp., has seen his fair share of ripples, and much of them seem to emanate from the nondestructive testing (NDT) of welds. But NDT itself didn't set the ripples in motion.

Nov 05, 2021 The Miller weld mask has some cheater lenses available that do straight magnification, up to 2.5 diopters. But I have an astigmatism so that won't be good enough. The weld mask comes with an empty cheater frame, so you can fill your own prescription. I took it to Costco and they said they could not provide lenses for it.
Feb 28, 2009 To prove this, if you do use a torch to re-melt, or just bring a MIG weld to cherry red and allow it to cool, it will become soft, and easy to hammer and grind. Still the same wire, but a slow heating and cooling cycle anneals the weld bead and HAZ.
Feb 17, 2004 When welding butt joints close fitting metal backer might might help torch shielding gas shield back of weld. One of Lincoln Electric's TIG instructors use aluminum foil. Rocky D. has posted picture of production welding ficture that included this feature. This reqires a little joint gap to work and I remember your manifold welds having plenty.
Jan 09, 2012 If you are welding 0.062 inch thick 6061-T6 there is no need to bevel the edges or to use a root opening. A square groove preparation with a tight root is fine up to about 1/8 inch thickness unless your welding machine is less than 200 amps. The aluminum can be welded with AC and argon shielding gas or DCEN with helium.
May 06, 2007 Ok, I have a shop where we weld a corner to corner 1/4" 5052 aluminum plate. After welding, the part is dressed and the weld is ground off, sanded and then powdercoated. Occasionaly we will get pin holes during the sanding process (around 1 out of 12 parts) and will spend hours of man time trying to fill these little pin holes.

作者: Justin VossApr 09, 2006 The tig is a Miller DX, and the filler rod I was using was aluminum labeled as ER4041 which says recommended for welding 3003, 3004, 5052, 6061, 6063, and casting allows 43, 355, 356, and 214. I remember at the sore there was another kind of aluminum filler rod labeled as something else, maybe I am not using the proper filler rod as well?

I have no experience welding aluminum but this seems like the fastest way to fill them. The parts will be painted after they are finished so I can grind the welds down flush when they are done.

May 02, 2019 I had one for close to 20 years and recently stepped up to a Miller 211. The sidekick is perfect for bodywork, sheet metal and mild fab work. My buddy bought it off me and uses it for the same purpose. In my opinion 1/4 steel is getting too thick for it but it will weld 1/8 no problem. Sent from my iPad using The H.A.M.B. mobile app.
Apr 26, 2005 First of all, the constants throughout this post are that a Miller Dynasty 200 DX is used, and so is a 3/32" 2% Thorium electrode. The problem is that when trying to run an autogenous stringer bead weld on 1/8" thick 1020 steel, the arc will not stay centered on the end of the electrode. It strays to one side or the other of the electrode.
Dec 05, 2004 Welding up mild steel- sticking the tungsten- you stop and grind it so contamination doesn't effect the weld. Now,you weld for a while, an decide to ball the end for aluminum. If there was contam in the ground tungsten, it will still be present when you ball it.
Jul 23, 2016 Welding used aluminum castings, even those of known good alloy can be dodgy because they're porous and absorb oil. I know what you guys mean re: grinding it out, and I was planning to do a once-over with a carbide burr after using heat to get most of the JB weld off.
