Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.

What is the raw material used for cotton?
Cotton comes from the cotton plant. The seeds of the cotton plant are contained in a capsule called a boll, each seed surrounded by fibres of two types. These fibres are are removed by a process called ginning. At the first ginning the longer fibres, called staples, are removed and these are twisted together to form yarn for making thread and weaving into high quality textiles. At the second ginning the shorter fibres, called linters, are removed, and these are woven into lower quality textiles including the Lint. The commercial species of cotton plant are G. hirsutum (90% of world production)

What is back step welding?
Backstep welding is a technique to avoid distortion while welding on thin sheets. In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left. As each bead segment is placed, the heated edges expand, which temporarily separates the plates at B. As the heat moves out across the plate to C, expansion along outer edges CD brings the plates back together. This separation is most pronounced as the first bead. With successive beads, the plates expand less and less because of the restraint from the prior welds.
When would you use a butt weld?
This process, called the butt-weld process is the basis for our current pipe-making procedures. In his method, thin sheets of iron were heated and drawn through a cone-shaped opening. As the metal went through the opening, its edges curled up and created a pipe shape. The two ends were welded together to finish the pipe. The first manufacturing plant to use this process in the United States was opened in 1832 in Philadelphia. So the method is the two sides are welded as they butt together without overlapping. The same method is used to weld two pipes together as they are butted together and welded around the seams.

Check first with your community college as they very often have contact with companies that are looking for graduates of a welding class. Check local phones books of companies that do welding and stop in and ask if they are hiring
Do have to take stick welding before tig welding?
I was taught oxy/acetylene welding first, then stick. TIG welding is just like oxy/acetylene except much easier (less variables and a foot control to make minor corrections or even pulse the weld) I would recommend you learn both. TIG welding for precise/clean welding. Stick for some larger, perhaps special welding (hard facing tools - bigger pieces of steel).
