In the "professional" welding world, does anyone ever cap a 7018 root pass weld with 6013? 6013 seems to be sooooo much "prettier" looking than 7018 in the hands of a skilled (or not so skilled) welder. I know that 7018 penetrates better than 6013 and also has a higher tinsile strength rating than the 60++ rods as well. I'm just wondering if going from a 7018 "root" pass can be capped with a 6013 for cosmetic reasons. Or, does capping a 7018 with a 6013 actually weaken a weld itself? I know that the pros make root passes with 6010/6011, then cap with a 7018. The question I have appears to be going "backwards" I know, but is it ever done that way????Or....How about capping a 7018 with a 7014 or 7024? I know that the 7018 is the low-hy rod and helps to prevent cracks due to hydrogen. However, I can make better looking welds with 7014 and 7024. The only problem I have with going to a 7014 or 7024 is the deposition rate. The 7024 looks beautiful, but it's INSANE with pouring out filler metal and sometimes, I just don't want such a thick and fat looking weld. 7014 1/8' is a close second in depositing a ton of weld, which is why I'm asking if 6013 can be used instead.Finally....Is it just best to try to cap a 7018 with another bead of 7018? I think I already know the answer, but like I said, I can make a cap weld with 6013 look sooooo much nicer. I'm just wondering if that's ever done in the "real" world, or am I thinking bass-ackwards? Disclaimer: My welds with 7018 are not for critical structures that would involve safety of life. I'm just making a small table top bench grinder stand. In the future, I'm making a thick steel bumper for a jeep and will wonder if I can cap the 7018's with 6013's as well. Thank you from a "hobby welder" and NOT a professional.

Reply:IMO you should either learn to run 7018 or just use a different rod for the weld. Just about any rod would be sufficient for what you're doing.My name's not Jim....
Reply:For that application, I'd just use 13s for everything. Wouldn't bother with low hydrogen rods.

Reply:Practice some more with the 7018. Once you get a feel for it you can really turn out some nice welds. Plus it'll be good practice if you even need to build something using 7018.IW Local 580 NY, NY

Reply:Use 7018 3/32. You can't beat. What brand are you using ??? 3/32 better control than using 1/8.
Reply:I seem to use mostly 3/32 7018. Now that i am used to it I dont like 6013 - I have noticed that the 2 rods seem to want completely different techniques to get a beautifull bead. I think I remember using 7018 at 60-80 amps and keep a very short arc (maybe zero) and do a forward whip - take your time and dont rush. when it is just rite the slag curls up by itsself and you dont even have to pick up a hammer. seems to be helpfull to keep a very precice arc length and a very precice,constant whip motion. I even do sheet metal with 3/32 7018. Just my 2 c.
Reply:Mixing rods mixes alloys. Different rods are made up of different alloys.Lincoln recommends tacking with 7018 if the final weld is going to be made with 7018. Try tacking with 6013 and welding with 7018, you'll see how different the final weld runs as you go over the tacks. It will run even over a 7018 tack, and run sorta funny over 6013 tacks"Any day above ground is a good day"http://www.farmersamm.com/
