stick practise 7/18/8

admin

Would like to get your input on what I did right and wrong on the work pieces attached during last practice session.Two images show my first practice on vertical welds using 6010 at about 55 amps positive stinger negative work table.Other two show bent pieces and attempts at joining them using a saw tooth or zig zag pattern...second practice of joining similar metals using same stuff as above.http://i237.photobucket.com/albums/f...bon/Pic079.jpghttp://i237.photobucket.com/albums/f...bon/Pic078.jpghttp://i237.photobucket.com/albums/f...bon/Pic077.jpghttp://i237.photobucket.com/albums/f...bon/Pic076.jpg happy welding uall
Reply:What diameter 6010? The flats look way too cold. The others aren't bad for a beginner. Try turning it up some. A downhill vertical weld with 6010 should be almost flat. Learn to run stringers then worry about weaves. Weaves are pretty much forbidden by ASME and API codes. I don't know about the other codes. The 6010 electrode really only works well in a fillet or a beveled joint. The electrode was designed for downhill pipe welding (which always has a bevel or U/V groove) and that is part of the reason it doesn't work well at all for running beads on flat pieces.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:1/8"The flats were on the vertical and the instructor had me doing welds going upwards.As for stringers before weaves: I agree that this is what should be practised first. Just wanted to try that out! It was great to see the molten metal creeping across the open space between the work pieces!Yes, I started in the first few classes using 70 amp. Inst decided that it was too hot so went down between 55-60 amp.Have been wandering if I am not pushing the trode into workpiece deep enough on the freeze portions of weld. HAPPY WELDING UALL
Reply:Wow.....That's COLD.I generally start out 3/32" 6010 @ 65amps, and 1/8" 6010 @85 amps.I'll run hotter if the metal will stand it - depends on what I am doing.Later,Jason

Reply:By flats I meant running them on flat metal. 6010 is terribly hard to run uphill without that bevel or that corner. For that matter the bevel or corner makes it a lot easier with 7018 as well. I usually run 3/32 at about 80 amps and 1/8 at about 120. but I have literally burned tons of the stuff. On an open root uphill I run it from straight in to slightly under (pointing upward). On a hotpass I generally run it from slighty underneath on pipe and quite a but underneath on structural straight up.I really don't know why they want you to run it uphill. Until I went into construction it was always downhill unless you had a tight fit on the root pass. The API and ASME procedure both call for a ten class electrode (6010, 6011, 7010) downhill on the root and hotpass and complete with 7018 uphill. That is for welds up to 70,000 psi. In construction they had a proofed procedure for uphill root and hotpass on both pipe and plate. Nothing I did in construction even came close to the working pressures I was looking at in the oilfield and heat exchangers. Some of the heat exchangers were hydro tested to 60,000 PSI and all of the roots and hotpasses were put in flat or downhill. My guess is some engineer read the line in Lincoln's book where it says uphill roots are more difficult, require a higher degree of skill, and have a greater chance of defects and inclusions and decided that should be the procedure.Last edited by Jolly Roger; 07-20-2008 at 09:38 PM.Reason: left something outThe difference between art and craft is the quality of the workmanship.

Reply:Originally Posted by Black WolfJust read this & there is your damage....6010 is generally accepted as a "Whip & Pause" rod.  You still use a drag technique, coming almost 90 degrees to the work and a short arc to "dig" then backstep SLIGHTLY and long arc SLIGHTLY to "deposit"I have an apprentice that I am training right now, and he is having a time wrapping his brain around how to use the 6010 as well.  Got too used to 7018, and is fighting keeping his hands in motion.
