When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
It depends on what you're welding and what kind of weld you need. For an extremely strong weld where you don't want to transfer as much heat to the surrounding areas, tig is the way to go. Tig has the option of melting only the source material (together), so if it is better than no material is added, then tig is the better process. If you want a small, uniform weld, then tig is also superior. Mig is wire-feed and so adds material to the pieces being welded. So it is better for filling areas or adding superior strength. If the material surrounding the weld can take the heat or doesn't matter if it is deformed or discolored, then mig welding is the way to go. A good discussion of Tig and Mig welding is here http://www.ridgecrest.ca.us/~biesiade/weld.htm.
Aluminum is one example of a metal that cannot be MIG welded and must be TIG welded. The limitation of MIG is usually the heat it can produce versus thickness of the material. One quarter-inch thickness is usually about as thick as you can weld with either MIG or flux-core wire feed welders. Anything else will require the heat energy available with a stick welder.
Yes In fact Miller includes a table for Copper TIG welding in its charts. Similar setup to steel but almost double the power. Copper dissipates the heat faster so you need to put it in faster. Local welding supply place carries filler rod (I think it has higher silicon to help flow).

This a learned skill, basically it is very similar to some of the skills learned when gas welding. Both processes require a source of heat to melt the base metal and a separate source of filler material . Both require the use of two hands. The exception is when you are fuse welding. Melting the edges of two pieces to flow together.
can weld aluminium with a mig or tig welder

Silicon is added to the tig rods in production. Use a gas weld rod which does not have the silicon and the weld will be full of porosity.
The three ways you would weld stainless steel are; 1. laser 2. friction 3. TIG Only TIG should be considered for nonproduction welding.
Tetanus is a disease that affects the muscles and the respiratory system. The difference between tetanus and TIG or tetanus immunoglobulin is that the latter is a form of preventative vaccine for tetanus.
Miller TIG system are well used systems. The Miller TIG systems are used for welding, calculating the costs of welding and materials, and showing how to weld.
Filler rods are used to add metal to a molten weld pool during the welding process and electrodes actually have electricity running through them to deposit metal into the weld with the exception of TIG welding where the tungsten electrode is used solely for heat.... Hope this was helpful
Is this a gasoline or diesel powered unit? If so the lag time between striking an arc and establishing an arc makes it difficult to use for TIG. If not, any DC supply can be set up for TIG. Not for aluminum... Check with your welding supplier.
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
One method is Ultra Sonic Sound, another Die Penetration.
Welding is the fusing of to metals, but the term "fusing" in a welding shop is the melting together of to materials without using filler rod. Usually done with a TIG Machine. The process results in a small weld, that does not need to be ground flush, because it already is. The only problem is that a "fused" weld isn't as strong.
