Here are some more information for Tig Tack:
Welding is a complex subject, and this article is far from being comprehensive on any aspect of it. However, one thing that it attempts to cover is a few absolutely necessary requirements and a number of basic beginner mistakes that one can easily avoid.
As a quick introduction, the most frequently used and easiest-accessible welding processes are arc welding/gas welding (including tig welding and mig welding).
Arc welding describes welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes protected by a kind of inert or semi-inert gas, known as a shielding gas, and/or filler material. Arc welding is widely used because of its low capital and running costs.
MIG (Metal Inert Gas) and TIG (gas tungsten arc) welding are kinds of gas metal arc welding. During MIG and TIG welding, continuous and consumable wire electrodes and a shielding gas are fed through a welding gun. Constant voltage, direct current power source are usually used with MIG and TIG welding, but alternating current sources can also be used. Originally used for welding aluminiums, gas metal arc welding was also soon applied to steels because it allowed to reduce welding time substantially.
Some advantages of MIG welding are that it is easier to learn, longer welds can be made without the need to stop and restart, and little post weld cleaning is necessary. The downsides are an oxidized weld deposit, unstable arc, and weld porosity. Advantages of TIG welding are that it allows welds of higher quality, with or without filling metal, good control of heat, and low distortion. Some of the issues with TIG welding are a somewhat erratic (wandering) arc, a high electrode consumption, and a certain porosity of the weld.
Some of the most basic and frequent mistakes in (mainly MIG, since it is the most relevant for most readers) welding, from our experience and after extensive research, are the following:
1) Not cleaning the parts and weld surfaces properly. As most experienced welders say, this is a very frequent beginner mistake. Any paint, dirt, and similar materials can lead to problems and a bad weld as a result.
2) Using the wrong kind of gas for gas welding. Many people will opt for cheap gas, which is however sometimes not a good idea. While simple CO2 is cheap, a mixed gas will often produce better results while MIG welding.
3) Wrong polarity. This can produce a bad-looking weld bead.
4) Wrong contact tip sizes.
5) Inadequate travel speed, i.e. going too fast or too slow.
6) Insufficient shielding - e.g. not blocking the wind while welding.
7) Welding too cool on a massive piece of material, which results in a lack of fusion.
Underbuying, i.e. picking a too small welding machine for the material thickness required.
9) Not maintaining the wire feeder's wear components, like liners, contact tips, and other parts.
10) Mismatched filler material, i.e. not having the right tensile strength.

Welding Carbon Steel Pipe To Stainless Steel Pipe
The standard welding processes such as TIG, MIG, and stick can be used to weld carbon steel pipe to stainless steel pipe. Standard carbon E-class welding electrodes such as E70 and 7018 can be used for MIG and stick welding respectively. However, using such welding electrodes on this type of welding, the welding quality may be compromised due to lack of chromium and nickel in the alloy. Hence, it is important to use high-carbon stainless steel electrodes to have a strong weld joint between the steel and stainless pipes. In particular, type 309 welding electrodes have the correct composition ensuring a proper weld with correct penetration and structural integrity. Similarly, the following steps must be used in this type of welding:
Step-1: Load or spool the MIG welding machine with the type 309 welding wire after removing already loaded welding wire used for other jobs.
Step-2: Replace the gas with the three part shielding gas mixture. It is necessary to mix the gas thoroughly before attaching the gas bottle to the MIG welder. The method used is to place the gas bottle on the floor horizontally roll it back and forth to mix the gas thoroughly. After that fix gas gauges to the three-part gas bottle.
Step-2: Now switch on the MIG welder and adjust the correct heat and wire speed levels. It is essential to note that the standard heat settings (used for carbon steel) will not be adequate for welding stainless steel as higher amount of heat is required to weld stainless steel. Best advise is to refer your welding guide to verify the initial test setting for your heat and wire speed. Once you adjust the heat levels, carry out a test pass with the welder to see that the settings are correct.
Step-3: Cut a piece of stainless steel pipe and a piece of carbon steel pipe with required lengths using a band saw. It is important to note that when cutting stainless steel using a band saw, reduce the speed and at the same time use cutting fluid to keep the band saw blade cool.
Step-4: You need to have 20-degree bevel on end of the cut pieces of pipe. This is done using a grinder by holding it at a constant 20 degrees to give you an even fill line. Make sure not to touch the grinding pipes because the pipe will get very hot during grinding.
Step-5: Once the pipe edges are grounded correctly, place one beveled end of the steel pipe against the beveled end of the stainless steel pipe allowing a welding gap about 1/16th of an inch between the two pieces of pipe. Then place a tack at the weld joint to keep the pipes together. Similarly, roll the pipes and provide a tack at one inch interval around the entire circumference of the pipe. ItÕs necessary to maintain the 1/16th inch weld gap right through out the circumference.
Step-6: Now start welding the pipes together. Start the weld from the stainless steel pipe and gradually pull the puddle onto the carbon steel pipe. Also, roll the MIG gun in a circle to flow the puddle to create good weld while watching the bottom of the weld to make sure proper penetration. During the welding process, if you note that the carbon pipe is under-cutting, it is necessary to reduce the heat on the MIG welder and repeat it.

Help - how to weld metal bars into shelves?
next few weeks at work i'm planning on turning a bunch of steel and aluminum bars (from the scrap heap) into different sized metal shelves using a TIG welder. i haven't used the welder in awhile but i planned to be supervised by an expert. So my question is really asking for tips/pointers into putting a metal shelf together.
I understand that steel and aluminum will not combine.
The shelves will be used to hold computers and monitors and other necessary equipment for a combustion experiment.
Is there a systematic process (for a shelf specifically) into assembling the bars? How will i be able to clamp it down if the bars are going to be different widths and at right angles? Once the frame is built, there may be an option to weld metal boards, how can that be done? When will a tack weld be more useful than a line weld?
This is the first time that I will be making metal shelves, so any extra tips beyond the questions posted will benefit me greatly.
I hate to bring problems up for you, but you can't weld aluminum to steel or vice versa. The two metals will not mix.
Also to weld aluminum your tig welder must have high freqincy on it also. Mosy welders don't.
If you are going to use sheet steel for the shelves and want to use the aluminum bars as the post, there is a way you can do so, however it will require buying some steel pipe with the inside diameter a hair larger than the aluminum bars.
drill a series of small holes 1" apart down one side of the pipe and then cut into small nipples between the holes. leave about 3/4" on one side of the hole and 1/4" on the other. Tig the pipe to the plate metal with the 3/4" toward the plate where you want the post to go on top and bottom of the bottom shelves,( if you want some short legs on the bottom of the rack) on bottom of the top shelves and on top and bottom of all the shelves in between.
Cut the bars to fit and then use self tapping screws to attach them as you put them together.
All it will only take is a small tack weld on both sides of the pipe. Maybe a 10% to 15% weld. There isn't any sense using up a lot of argone gas, welding rods and time welding them 100%.
It is also a question of how heavy the sheet steel is, how far between the uprights, and what will be put on them as to whether you will need bracing such as angle iron under the front and rear lip of the shelves. The heaver the load, the bigger the angle needs to be but 3/4" x 3/4" should be enough even if you have something as thin as 20 gauge sheet for the shelves.
If you are useing something like 1/4" plate for the shelves, you shouldn't even nee the angle at all unless you want the post spread a part a long ways.
Good luck and God Bless
Dennis.
P.S. If you have any more questions e-mail me and I will be happy to help.
The extra that you added didn't help me and I doubt anyone else at fifureing out what you are trying to do. If you will e-mail me, I will give you my home number and you can call me and then maybe we can figure out what you need to know. I mean I have some questions about what you are talking about and can't give you a correct answer with out my questions being answered and it will be a series of question, answer, question, answer, etc.
I'll be happy to help you if you will e-mail me. If I can that is. lol.
I did find out from someone that read your question that you don't have to have Hi Fre. if you use helium gas instead if argon gas. First time I ever heard of it after 35 years of welding but the guy seemed like he was correct. Learn some new trying to answer someone elses question. Oh well. lol
