A Welder Fabricator is some one that welds as well as assemble parts to make machinery.
There are classes for welding at most vocational training places, as well as some that are independent. You don't need to go to school for it however if you can prove that you know what you are doing. Most places that hire welders will ask for a demonstration of certain types of welds regardless of your background, unless they already know your work. Hope that helps you.
If you are welding two pieces of metal together, having the work as flat as possible allows for the best access for the weld to be proper. There are often more times then not that the work will not be in a flat position so if you are really just starting out, your practice welds should be made on flat work to get the skill necessary to weld well in other positions. When a welder must certify for their appropriate welder's certifications, all of the samples are basically flat work. Simple tack welds to deep fill welds are required.
A type of weld produced around the outer surface of a cylindrical workpiece. Circumferential welds are used to fabricate structural pipes
Arc welding is the process of joining two metal pieces together using a welding machine, electrodes, cables and clamps, and the metal to be welded. You will also need tools for preparing and cleaning the welds, and you will also need safety equipment.
I am replacing my radiator support in my 93 Nissan sentra SE-R this is the best i have found to do the job. i am using mig welder also to replace the welds. go to this link ---> http://www.goodwrench.com/gmgoodwrenchjsp/gmspo/Cadillac/Eldorado/1992-1999/02_Radiator_Support_Assembly.pdf
higher cost, low heat input
Generally the title of 'fitter' is applied to the person who does the layout, preparation and positioning of parts to be welded. They may also do the cutting of the parts to be assembled and the tacking the parts in place. A 'welder' then comes behind the fitter and welds the parts together. A 'fitter and welder' does the entire job and all the aspects of it.
Standard welder sizes are between 5 to 500 kilovolt amperes, but micro spot welders may be as small as 1.5 kilovolt amperes. They are used in many types of industries which require precision welding.
