Here are some more information for Welder Mig:
Thermite welding is a process that results from a chemical reaction that is created through heating metal to a super high temperature between two reducing agents, one of which will be a metal oxide and the other aluminum or sometimes other types of reducing agents are used. This can be done with pressure or without pressure. At this point the liquid metals will produce a filler metal.
The chemical reaction that is produced will give off a temperature of 4500 degrees Fahrenheit or 2482 degrees Celsius. This metal that was created with high heat is found in a crucible that is part of the weld joint. It is actually above this joint.
This chemical reaction or exothermic reaction as it is also called, will be slow compared to other processes; it takes about 20 or 30 seconds and it doesn't matter how many chemicals are part of the process -- it still takes about the same amount of time.
When the welder wants to weld two things together, the two parts are lined up equally but a gap is made between the two pieces of metal. Before the two pieces of metal are put together there is a mold that is put between them so that the hot steel can go into the mold. Because this new metal is hotter than the base metal, the base metal will melt along the edge of the pieces to be welded.
From the crucible, the hot metal now allows heat to be lost and this causes the metal that has been melted to become solid again and a process called coalescence happens and this completes the weld. In the event that you have larger parts that need to be welded, you may need to preheat them and this is done inside the cavity within the mold. This is done to bring these larger pieces to the correct temperature for welding and the process also help to make sure that the mold is dry.
When you have smaller parts, this preheating is usually not necessary. The mode that is used for thermite welding is the automatic one which means that once the chemical reaction starts, the process continues until it is finished.
The process of thermite welding uses gravity to bring the metal down to the cavity between the two parts through the gap. This practice of welding is like pouring castings in foundry type businesses. The basic difference between these two processes is that in Thermite welding the temperature of melted metal is higher.
After the metal filler cools you may find extra filler on it and this can easily be removed by using a machine, grinding it or by using oxygen cutting. However, when the weld is finished you the finished weld surface is usually very smooth and you don't have to worry about doing any finishing.
Thermite Welding is used a lot at the Railroads to weld the rails together. A couple of advantages of this type of welding is that it that it doesn't need a power source that is outside of the process because the heat is produced through the chemical reaction and you can join parts if they are larger and have heavy sections.

Pros and Cons of MIG Welding
MIG welding, as most of us are aware, is a semi-automatic arc welding process in which a continuous, consumable wire electrode and a shielding gas are fed through a welding gun. At the end of the gun, there is a contact tip which passes electricity to the wire. Both the wire and shielding gas are activated to create the weld when the operator depresses the trigger of the gun.
Pros of MIG welding
MIG welding is quite popular as it is easy to learn and calls for no special skills. Even a first-time operator will be able to achieve a good weld with minimum practice. People favor MIG welding as it is a much faster than Stick welding and saves time. Thus operating cost of MIG welding is lower than Stick welding because of this saving of time. MIG adjusts to limited electrode length and this allows for longer welds with fewer interruptions.
Besides, there is also no waste of filler metals and generally speaking, thinner materials can be welded far more easily with MIG than Stick welding. One more reason people favor MIG welding is because MIG welding is a tidy process and does not require chipping slag as in Stick welding. MIG certainly makes for very convenient weld tacking and fitting of parts and there is very scant stub loss due to the continuous spool of filler metal.
MIG welding is versatile and capable for a variety of applications, including - trailer hitches, auto body repair and restoration, farm/ranch equipment, household projects, repairing wheel barrows, bicycles, etc. This type of welding demands less time when compared to other types of welding processes.
Cons of MIG welding
The initial cost of MIG set up is high in view of the regulators and shielding gas - though some MIG welding may be done with self-shielding flux core and without gas or a regulator.
It is indeed a fact that all types of material can be welded with a MIG machine. But, in the MIG process different materials require different wire and gases. For instance mild steel can be welded with either self-shielded wire or with CO2 or a CO2 mixed gas but aluminum material requires the use of Argon gas.
It is inadvisable to weld through dirty materials with MIG machines. It is said one should always weld on the cleanest possible material, so for best results scrape off paint, rust or other debris where the weld is being made.
There is no denying that MIG welding equipment is more complex, expensive and less portable and the welding gun is difficult to maneuver. Filler metal can become tangled within the wire feeder making the operator feel annoyed and also adding to downtime. The operator has to patiently keep leads and liners in straight position to allow for proper feeding of filler metal.
Summing up
When electrically charged wire is feeded into the welding arc then it is MIG welding. MIG is commonly preferred because the welding leads are very easy to perform. As a matter of fact, it is said that even robots can be utilized to get the mechanical job done. MIG welder is capable of working with almost all kids of metals, though aluminum and mild steel are the most popular ones.
