Professional welding actually involves expertise & experience. A fairly extensive-knowledge is required to become an expert. Many years of exposure & skill are necessary to master the art of welding. After understanding the basics, one can learn more complicated skills.
First and foremost, one has to take safety precautions. Otherwise, unforeseen circumstances may even prove to be fatal. Damage to the eyes is a possibility due to intense light beams that emerge from the course of action. As electricity is involved in certain cases of welding, death by electrocution is a possibility. Before starting welding, helmet has to be worn for protecting eyes, hair, head & face. Wearing protective gloves & clothing is a must.
Arc Welding:
Arc welding is the most common technique used. It is the first lesson for welding. Instead of using a gas torch, high voltage electricity is to be used. In arc welding, a spark/arc is able to melt a metal & form a weld. This process is accepted by many as it is more accurate & produces a cleaner & stronger weld. In the category of arc welding, seven different methods are there to choose from.
Shielded metal arc welding may be the most suitable if you have large welds or metal welding in not-so-normal angles & positions. In this method, the electricity passes through an electrode using which metals can be melted. MIG welding (Metal Inert Gas welding) will be useful in a welding project which requires more speed. In this method, rods need not be used. In its place, equipment has to be used that passes current through a metal tip that does not melt. A separate piece of continuous wire is to be fed to the tip which forms the weld. Tungsten inert gas welding is slightly similar to MIG welding. It is applicable in thin materials where high quality weld is required & where speed is not necessary. There are other methods also – namely Flux-Cored arc welding (FCAW), submerged arc welding (SAW), plasma welding etc.
Aluminum Welding:
Aluminum is the most difficult alloy. Initially, aluminum oxide should be cleaned from the surface. Heat treatable aluminum alloys receive their strength from a process called ageing. Notable decrease in tensile strength will happen when welding aluminum due to over-ageing. For all other information on aluminum welding processes, please visit the homepage or any of the links connected to this.
Aluminum alloys can be divided into 9 groups.
Designation Major Alloying Element
1xxx unalloyed (pure) >99% Al
2xxx Copper is the principle alloying element.
3xxx Manganese is the principle alloying element.
4xxx Silicon is the principle alloying element.
5xxx Magnesium is the principle alloying element.
6xxx Magnesium & Silicon are principle alloying elements.
7xxx Zinc is the principle alloying element.
8xxx other elements (including Tin, some Lithium compositions)
9xxx reserved for future use
Aluminum alloys are readily available in the market. We can get them in various product forms. The following are the factors affecting aluminum welding.
* Aluminum Oxide coating.
* Thermal Conductivity.
* Thermal Expansion Coefficient.
* Melting characteristics.
Other welding Methods:
There are some other methods – resistance welding, energy beam welding & solid state welding. All these methods are useful in industrial applications where large scale & specialized requirements are involved.
What we have dealt with so far are only basic concepts. These are the fist lessons or fundamental steps from which on can go further to acquire more knowledge about welding procedures. One has to remember only a couple of basic methods. One has to practice a lot before arriving at a standard of excellence. Certain processes will bring easy results & some may not. Sooner or later, one will reach a stage & style which will be most comfortable for future operations.

Help answer the question about mig welding
How much does all the welding gear cost for MIG welding?Yes, I am looking for a number estimate. Around here all the jobs I've seen at least require your own safety gear, like helmet and gloves, some require you to have your own tools. I can look up helmet and gloves online, but I don't know about all the other crap.
Im just looking for a rough estimate of how much guys who buy all that crap have to spend. I'm guessing around $800 but I could be wrong.

ok ok
But you have to promise to watch my new beef jerky in the oven video …lol
mig welders need a shield gas unless u use flux core wire.
the best way to get a nice bead id to set your heat, and turn up the wire feed speed,…..strike an arc and turn down the wire feed till you get a nice bead with little splatter
Possum
you may want to do a search on that (google). That may give u the help u need. Good luck!
First off, are you a good welder? If you have limited experience, you will not get good weld penetration with a MiG welder. Also if you use one of the cheap welders that you can buy at Lowe's or auto parts stores, they don't produce enough power to get a deep penetrating weld.
MIG means machine inert gas. Those cheap welders are called MiG but are just wire feed welders and not MiG. You must use gas to get a good weld. A cheap gas to use if you are a good welder is carbon dioxide. The weld is good only if you are very experienced. Next you can use 75/25 gas mix which is 75 % argon and 25 % carbon dioxide. Doesn't take as much skill and produces a reasonable weld. For a top job, use 100% argon. It costs a little more but does so much more.
If you buy a MiG, get a good one in the $2000 dollar range, such as a commercial Lincoln, Miller or Hobart. Go to welding school at your local Vo-tech and practice, practice, practice. Once you learn, you can weld car doors, bodies, exhaust, frame or anything else you so desire. As a good MiG welder, you can get a top paying job and be set for life. I prefer a auto darkening helmet when I weld. It makes learning so much easier.
Hope you are not using pure argon (just a wast of money for pure). You should be using a 75/25 mix of argon/co2. The shielding gas shields the molten metal from the atmosphere, more so oxygen and nitrogen to prevent porosity, and reduce the chance of cracks. To rent a tank you should call a local welding supply for the prices as the price varies quit a bit by location. I am in Ohio so a price I would give you would not be true for your location.

thanks
you’ve got some pretty good videos and now I’m thinking about buying that little arc welder…. How thin of metal can it do and can you make a video trying the welder at all amp.
i have seen worse welding from 30 year olds realy nice job
Consistency, quality, and operating cost. Remember, you don't need highly trained welders, just machine operators to run them.
I would recommend Lincoln Electric wire it’s nice and you can make pretty welds with any wire it just takes some practice and if you shine ‘em up, you can get you welds to look like TIG welds!!!
ok thanks. I have a REALLY tight budget so i would rather use cheap wire..but i still want the weld to look and perform decent. Im gonna lift my lawnmower about 4 inches so i need it strong and i want it to look as good as possible so i was just asking. Thanks a lot!
That weld looked pretty good. better than I everd did with that machine.
Mig welding job listings in Dallas TX:

Do you recommend a certain brand of flux wire? And is it hard to make the welds look decent?
I used it to make a “suit of Armor” like dude that was made of tacked pieces of paper thin tin like steel and it worked if I hit it real fast. I mainly use it for 16gua-3/16ths/ Sure I’ll make another video with it turned up. I’ll go do that right now as a matter of fact.
If the nozzle is arcing it means the insulator between the nozzle and gas diffuser is probably shot. You will have to either replace the insulator or make sure you don't touch the work piece.
Arcing outside the weld zone is not good, can lead to inbrittlement and cracking.
Oh, and good job on buying a miller…i hate it when people buy crap gear and expect miracles(or ask me to perform them with their junk welder)
There is a big difference between MIG and TIG welding, in both the process, and the skill level required of the weldor. They really are two different processes altogether, and the MIG is the much easier of the two.
There is much to read on the web, including some great information at the Miller and Lincoln websites. They can give you a pretty great overview of TIG welding. But, as with many skills, it takes hands-on practice as well as study, to be successful.
If your fiance has ever welded with a gas torch, he might already have the skills he needs. Unlike a MIG welder, a TIG does not feed an electrified filler wire for you. You are in control of a separate heat source (the torch) that you must manipulate in order to melt the base metal together, while adding the filler by hand to the molten puddle you're creating. It's the same way a gas torch works, just with electricity, rather than gas, as the heat source.
The tricky part comes in learning how hot to make the puddle, how much heat to apply (with a foot or hand controller), and how to coordinate the filler at the same time. Quite often, TIG welding involves metals like aluminum or stainless, which have their own quirks that need to be considered. It's by no means impossible to learn all of this…and it can be a very valuable skill to have, often paying higher than MIG welding jobs.
If your fiance shows this prospective employer that he is a professional who takes pride in his work, has studied the subject, and is willing to learn, he may get his foot in the door and start down a new path on his welding career. I wish him the best. Study all you can, and if you know a buddy who is good with the Oxy-Acetylene torch, go visit him right away for some practice!
Best of Luck!
glad you asked, Mig welding is really a simple task if you can already stick weld. what you see is what you get with a mig. follow the following process and you'll do great.
if right handed hold the handle slightly to the left just enough to see the wire sticking out of the nozzle, weld to the left in an overlapping circular pattern usually between 1/4 and 7/16 wide the lens should be sufficient if for arc welding. a quick practice on scrap metal should ease your concerns quickly. you will see the deposited weld in the lens and no chipping needed
