typed in rec.crafts.metalworking the following: Just welded with 7018 for two days straight, making ramps for the 30,000 lbs forklift. And so I am wondering, will I benefit somehow from using MIG instead of stick? i Mig is a lazy man's welder. Don't need to keep changing electrodes. As far as I can tell it has no other advantage for most applications. There being nothing wrong with that btw. Stick allows you to use a smaller machine to weld thicker materials. An equivalent sized MIG will be a big assed workhorse of a beast in most cases. That being said..for normal 1/8-3/8' weldments..MIG works pretty darned nicely and its a heck of a lot faster and easier to weld aluminum with a proper feeder/gun than it is to weld with aluminum electrodes Ive got a MK products feeder and an Prince XL gun and welded up a friends aluminum rear bumper on his racing pickup truck a hell of a lot faster than I could have with TIG and did as pretty a weld as TIG There is a place for all three technologies. With some over lap. As the instructor in the welding class pointed out - with stick, you need at most a 60% rated powered supply. That is, a powered supply that can run for six minutes straight in a ten minute cycle before it overheats. Which is just about the maximum time you can weld with a stick before it is too short and needs to be replaced. Wire feed, OTOH, can run without "time out" to replace a stick, get some coffee, have smoke, etc. Natcherally, Welders like stick, and managers like wirefeed. B-) Except when they won't do the job - for various values of "do the job". (I.e., How many units need to be welded before automating the process pays off?) -- pyotr filipivich "With Age comes Wisdom. Although more often, Age travels alone." |

" fired this volley in
: Getting a good solid weld on a very short space is hard, but in this case a crappy ugly weld is good enough. But, Don, in keeping with the "haven't you just gone out to the shop to make a somethin'" philosophy, WHY would you do a crappy job just to "get by". If you're already spending more of your labor than the part is worth, make it nice. That was why I recommended brazing. It's strong, it's easy, and it's _pretty_. Slap a shot of rattle-can on it, and it would look like it was forged from a single piece. Lloyd |

If you're already spending more of your labor than the part is worth, make it nice. Lloyd My philosophy is to make a part when it takes less time than trying to find an already made part. I am about ten miles from any industrial supply, so I tend to make things instead of buying. I make things strong enough for the use they will get. If you stick weld the rod to the bar with a gap and then flip it over and run another bead , you are likely to have a slag inclusion. But the part will probably last longer than I will. Would not recommend doing it if there was any stress or it was made from steel that is notch sensitive. Dan |

But then I have a LOT more stick welding experience tha wire feed experience and I can make a MUCH better job with a stick welder. A 6010 or 6011 "tack rod" would be a lot better than the 7018 or 7014 for the application. 6010 requires DC electrode positive to make a decent weld, so in most situations I'd be stuck with 6011 on a "buzz box" The application has no need for the extra strength of a 7000 series rod. And 7018 that hasn't been kept perfectly dry can be a trial. (like all Lo-Hiy rods) If you can stick weld that well, wirefeed should take you until lunch on a bad day to learn. But should he? Does he need to learn to use wire feed? The reason why I am asking is that we have both a stick and mig welder, and I historically used only stick. Just welded with 7018 for two days straight, making ramps for the 30,000 lbs forklift. And so I am wondering, will I benefit somehow from using MIG instead of stick? i As with any weldment, it depends on what you want for the finished product. Strength? Looks? Both? MIG does have flaws, cold lap and lack of penetration/fusion being the biggest. Unless you use FCAW, and then, you get a lot of spatter at times. Whatever you welded with 7018, I would trust ten times than if you had welded it with MIG, ask the guy who had his spare tire arrangement pass him on the Interstate. As with learning to braze small items to make intricate or small things, it depends on what you are doing, and what you want the final outcome to be. I have seen some of those sculptures that guys do in gas, and cut out leaves from sheets of materials, and they are just beautiful. Yeah, it's welding, but only slightly. Steve When learning to MIG weld I was aware of the ability to make good looking but poor welds, so I learned to weld with it properly. My MIG welds have the proper penetration and are as strong as other types of weld using the same materials. It seems to me that learning to MIG weld properly would be a good idea. Besides, it's fun. It is the only method with which I can write my name legibly. Eric |

But if you are not sure that you can tell that you are getting good penetration by watching the puddle, then you had better have a way of testing.

I dared not bring that up. Thanks for the laugh. bseg Larry...I thought you knew me better than that. I admitted it when it happened. I didnt "not talk about it" I knew that. Remember, I've brought it up before, too. I thought others could learn from my ****up. And Yes..I do make an occasional one. Like welding boat bunkers up and forgetting the ass end of the boat was hanging from an engine hoist and not forming the curve in the bunker....sigh https://picasaweb.google.com/1040422...68989920415378 Ayup. I remember that. I never hide from my mistakes or ****ups. Thats what pussies do. Nor do I. If we don't learn from our mistakes, we chance making them again. Talking about them increases acceptance and learning. Fortunately..that one wasnt quite..quite as spectacular as the tire episode.... Sigh giggle -- Liberalism is a pathology. |

It is just a torch, but with a very high temperature. So it does not work well with ordinary brazing rod. The high temperature boils the zinc. Get some silicon bronze rod. It works really well.

LLoyd I have a reasonable amount of silicon bronze on hand. It works much better than brass. Especially true if you are brazing galvanized steel. Probably costs more than brass since it is almost all copper. Dan |

LLoyd The only way to braze PROPERLY even with a gas torch. Heating the rod with a gas torch can work well in combination with heating the work if the rod is a bit too large for the job. |

Heating the rod with a gas torch can work well in combination with heating the work if the rod is a bit too large for the job. I normally braze by heating the parts and when I think the parts are hot enough touching the rod to the work to see if the parts are hot enough to melt the rod. You get other clues as to how hot the parts are by what the flu is doing. Ecept when tig brazing , there is no flu. ( I spilt beer on the keyboard and now I can not type the letter between w and y in the alphabet.) When using a tig torch and silicon bronze, it is okay to let the arc touch the rod. When using fuming brass, letting the arc contact the rod, causes the zinc in the rod to vaporize and causes a mess. Dan |
