Tungsten inert gas (tig) is often used for high-quality precision welding purposes. In this particular process an arc is formed between the metal and the permanent non-melting tungsten electrode. With the help of the torch the gas is fed, thereby it shields the electrode and molten weld pool. In case of usage of filler material, they are added discretely to the weld pool.
There are several benefits of tig welding and it takes into consideration finer quality welds, clear-cut control of welding variables such as heat, independence of spatters and low warp. Moreover, it can be used at lower amperages for thinner metals and they can be used on exotic metals.
It can be used on different types of metals, but most commonly aluminum is used in particular metals of a smaller thickness.
Almost all types of metals can be tig welded but the most recurrent metal that is associated with this type of welding process is the aluminum, predominantly smaller thickness metals. Even though there are several other set of processes that allows joining aluminum, tig is one such process that is most applicable in the case of lighter gauges.
On the whole, as a rule, the gas tungsten arc welding process is best for repairing aluminum.
* One of the main advantages of diesel generators is fuel efficiency. Generators with diesel consume less fuel than those that run on gas. Some diesel generators consume only partially their fuel load when functioning in the same capability as other generator types. This is why diesel generators are great for supplying nonstop power. They can therefore be relied upon to continually power refrigerators, computers and even house medical equipment.
* A portable diesel generator is sturdier than its complements. It can run for a total of more than 2000-3000 hours before you have to gravely think major maintenance work. You can simply see proof of diesel engine sturdiness just by looking at other equipment that runs on diesel. Heavy duty vehicles for example last longer than lesser ones used for transportation because they run on diesel.
* Normal maintenance is not a problem. This is because there are no spark plugs to maintain. You only have to keep in mind to regularly alter the oil and clean your unit from as often as the product manual tells you to.
* A diesel generator is ideal for rough terrain and rough work. These generators are many times more dependable in rugged environments than gas units. This makes diesel generators just right for offsite construction work and outside behavior.
* You will hardly have a problem with your fuel basis with a portable diesel generator. Diesel is in huge quantities almost anywhere. Just as long as a gas station is around, you are sure to locate some diesel supply.
* Diesel can be safely used in the majority instances. It is fewer flammable than other fuel sources. Diesel generators also do not contain spark plugs, which further lessens the chances of freak fires. You get immediate protection for both your property and your generator unit.

Explosive Welding Advantages:
(i) Ease of the process.
(ii) Extremely big surface can be bonded.
(iii) Welds can be created on heat-treated metals with no affecting their microstructures.
(iv) This foils can be bonded to heavier plates.
(v) Broad range of thicknesses can be explosively clad jointly.
(vi) Explosive bonds have a solid condition joint that is free from warmth affected zone.
(vii) Good explosive bonds typically contain strength equal to or greater than that of the weaker of the two metals joined.
(viii) Lack of porosity, phase changes and structural changes communicate improved mechanical properties to the joints.
Explosive welding Disadvantages:
(i) In industrial areas the use of explosives will be harshly limited by the noise and earth vibrations caused by explosion.
(ii) The rules relating to the storage of explosives and the difficulty of preventing them from falling into unauthorized hands can well prove to be the major obstruction to the use of explosive welding.
(iii) A limitation to explosive cladding is concerned with the fragility of the alloys. Metals to be bonded by this procedure must possess some ductility and some crash resistance. Metals harder than about 50 RC are tremendously hard to weld.
(iv) Metal thicknesses bigger than 62 mm of every alloy cannot be joined simply and need high explosive loads.
(v) Resources such as beryllium, tungsten, boron, glass and ceramics are not usually processed by explosive welding.

There are a lot of advantages that MIG welding has over other welding types. Following are some of the advantages,
• First of all it is quite easy to study MIG welding. You can turn into pretty good at excellence welds in a small quantity of time. You can purchase a decent MIG welder for under $ 500. Also, a lot of these machines will be able to run off of a normal 110v outlet. Cleanup from a welding session is minimal.
• The next advantage is speed. Since a solid nonstop wire is used there is no require to change rods. There is also no require for chipping the weld, as the sum of slag is reduced. Quality welds can be created faster than most other welding types. You must be able to achieve a higher output of work compared to most other types of welding.
• The removal of flux in MIG welding will help prevent slag defects in the weld.
• The shield gas helps guards the arc which eliminates the need to regularly replace the electrode. This will also help prevent weld splash.
• It is easier to weld thinner materials.
• Can be used on a broad selection of metals, including stainless steel, mild steel and aluminum.
• The welding procedure can be either manual or automated.
So as you can see MIG welding has a lot of advantages that create it accessible to the beginner.
