Welding aluminum is not easy. The real problem is that the metal heats up quickly and it also has a low melting point. Welding aluminum is not difficult if certain measures are taken. Some of the useful tips for welding aluminum are as follows:
First thing you have to do is preheat the aluminum with a blowtorch. Aluminum tends to distort quite a bit when a local hotspot is caused by a welding torch. Pre-heating the aluminum tends to minimize the distortion. Be prepared to move the welding torch much faster than when welding steel or other metals. Never stop moving the welding gun along the weld, as this will cause a localized area of the aluminum stock to heat up. Argon gas is also used to weld aluminum. But both argon and helium can also work depending on the equipment used.
Aluminum can be welded with a MIG welder also. When it comes to equipment the general agreed standard for welding aluminum is a TIG welder, the problem here is the fact that they can cost upward of $6000 to purchase. If tungsten electrode on the welding gun becomes contaminated, stop at once. When welding steel it is quite possible to fill gaps between the joining surfaces with the weld. This is just not possible with aluminum, so all pieces must be fitted together as tightly as possible so that a nice clean weld can be made.
Aluminum is a low density metallic substance used in a wide range of different appliances and fields. Having such a low density is not only an attractive feature of aluminum, it excels at conducing both electricity and heat, as a result of this, it is frequently encountered in power generators, the conduction of heat prevents from such appliances will prevent the wiring from melting.
In reality aluminum can wrap, crack, bend or simply not stick. To weld aluminum successfully and safely you need to follow these steps: Things that you need are TIG welder, Welding safety gear, stainless steel brush, argon gas supply and Heat sink. Wear a thick long sleeve shirt to prevent yourself from getting burned. Clean the aluminum pieces properly before welding them. Clean the aluminum by spraying the surface with electrical cleaner. Use a heat sink. Because of aluminum’s tendency to conduct heat very well you need to use a heat sink to clamp the aluminum onto in order to prevent the metal from warping or the workspace from becoming too hot to work around. If you preheat aluminum beforehand it will make the welding job easier. Preheat the aluminum by sticking it in an oven with a thermometer or by using a propane torch to heat the surface. See to it that pieces are flush when you weld. Aluminum has a tendency to preserve spaces between the metal pieces as you weld. Make sure the aluminum slides together as tightly as possible as you weld the pieces.

Nice work!
Thanks
It won't be easy. But, if the school where you take the welding classes is legitimate, they will have a program to help you find a job. If they don't have such a program, don't take classes there.
As someone who was active duty for 8 yrs. and 2 reserves, welding itself is not a rate but used in rates such as hull techs, launch and recovery technician and others. Usually an individual is picked to go to the navy welding class for 2-3 weeks based on the commands needs. If you get a four year degree you could get into the officer program. As far as just having college credits may give you a higher pay rate but not necessarily a job as a welder.

One of the highest paid of all jobs in this country are those who weld underwater! Temps underwater are always on the coldish side – and you will always be wet from the water and not sweat. You will have to really master both welding and scuba diving to survive, and even if you are the best of the best in the field there is danger involved in this career (it is the reason for the high pay, however).
Check out some machine tool and mechanic shops to see if they have an opening.
try to talk to friends and ask them if they can help you out…
they may know some people who can help you with your business
Advertise in the local news paper, place notes on bulletin boards, word of mouth, set up a shop with a sign out front, a sign on the side of your truck. These are good places to start. It all takes time to build.
Good luck. Look at this.

Hand welders are in demand. They work in factories, construction sites, ship yards etc. The difficulty is doing the job correctly and getting the training for it. If bad welds show up or are missed the welder is quickly dismissed.
Weld operators is the least technical of the welders. They place parts in fixtures which clamp other parts together. A mig robot will automatically quickly weld the parts and when done the operator will quickly remove and inspect the part. If the part is good the part will be packed for shipment. If bad welds are found the operator will mark the bad weld and place it on a rack where a hand welder will later reweld the bad spots.
At one time this operator job was the entry level job for welding. However with the decline in the automotive market, there are fewer openings. Plus the demands on the operators have increased including quotas and the quality demands to not miss bad welds.
