The simple definition of Welding is that the metals are heated in the way of flame or electricity to join the two metal so that they will melt and stick together. I think so you can understand better if it was in the easiest way to reply. It means joining unitedly who has been separated.

It is also referred to as the mendacity process where the heat joins together the broken metal or also defined as the two or more parts joined together through heat.

Commonly welding process is habitually used in metals and also thermoplastics. But it is said that it can be also used in woods.

Scientists have recently found that wood welding is the most complicated and challenging thing to work out. But also recently they found the new way to assemble two pieces of wood through mechanical welding.

This wood welding helps to make and produce new wood products that are environment-friendly wooden products. The wood welding process makes the wood weld through the frictional heat process to join the broken wooden pieces.

In the normal welding process, the pieces that are joined together is known as the parent material. And also the material that joins the broken pieces or the two different pieces that are known as filler or consumable. This form of material is known as the parent plate or also pipe, filler wire etc.

There are two types of welding available. They are:

  • Arc Welding,
  • Torch Welding.

These are the two types of welding available and the brief explanation of them is mentioned below:

Arc Welding:

This is one of the most suitable types of welding used in the welding process. Arc Welding is the types of welding that join or combine two materials by using electricity which creates the possible heat to combine those materials.

This type of Welding uses the welding power supply which creates an electric arc between the metal stick and base material to melt the metal which rejoins the broken or two different parts of the material.

Torch Welding:

This is also the most fitting type of welding which is easy to use and comfortable to handle. Torch Handling is an automatic welding system that is to direct the welding electrode into the arc, which conducts the welding power into the electrode.

It also conducts the welding power into the electrode and also which provide the shield in the arc area. The arc in the torch welding with a bend is used for the robotic arc welding applications which will also provide access to the weld.

These are the two types of welding that are used and you can get to know about the brief explanation of it.

How does welding work?:

1. Joining metals:

It is said that the welding process is a high heat process which will melt the base material with the addition of the filler material. The heat at a high temperature which causes a weld with a molten material which cools to form the join and it also will be stronger than any other parent material.

2. Joining plastics:

Joining plastics also the same process of joining the materials with the heat process as usual. And it is also used in three stages which will be useful. They are:

  • The surfaces are prepared before the heat,
  • The pressure is applied,
  • Finally, the materials are cooled to form to join the materials.

These are the three stages used in joining plastics.

3. Joining Wood:

As we discussed before, joining wood uses the heat generated by friction form to join the materials. It is also said that this the fastest material process which allows the wood to join without adhesive nails.

These are the types that how welding works..??

Types of Welding joints:

The five basic types of welding joints used in the welding are listed below. They are:

  1. Butt Joint.
  2. Lap Joint.
  3. Corner Joint.
  4. Edge Joint.
  5. Tee Joint.

These are the five basic types of Welding joints and the brief explanation of the joints are mentioned here:

1. Butt Joint:

A butt joint is a separate technique where the two pieces of the material are co-joined together by just simply fixing the both together.

2. Lap Joint:

A lap joint is a technique where a joint is made by the thickness of each member of the joint helps to fix together.

3. Corner Joint:

The corner joint may be also regarded as the butt joint by fixing two plates at the right of the angles at each other.

4. Edge Joint:

The edge joint is formed by the uniting two edges or the two surfaces that also especially at the corner.

5. Tee joint:

The tee joint refers to the welded point of the metallic materials that are joined on the same plane at 180 which forms the letter”T”.

These are the five basic types of welding points that are explained in brief.

MIG (Metal Inert Gas) welding:

The MIG (Metal Inert Gas) welding is the type of welding that is arc welding processes which uses a continuous child wire electrode heated and also feed into the weld pool and also welding gun.

The MIG is also known as Gas metal arc welding and it is useful to weld many different types of metals such as carbon steel, stainless steel, aluminium, magnesium etc..! The few advantages are the ability to join a wide range of metals and thickness.

The four most common types of gas that are used in MIG is mentioned below:

  • Argon
  • Helium
  • Carbon-dioxide
  • Oxygen

These are the four most common types of gas used in MIG.

The few most disadvantages of MIG welding is that they are sensitive to contaminants, also sensitive to winds, it has limited positions and also lack of fusion.

TIG (Gas Tungsten Arc) Welding:

Tig Welding which is also known as Gas tungsten arc welding is the type of welding which processes that they join metals by heating it by a tungsten electrode and also the workpiece.

It is said that the TIG Welders can be used to weld the steel, stainless steel, Chromoly, aluminium, nickel alloys, copper, brass and also gold etc. The TIG is useful for the welding process for the welding wagons, bike frames, lawnmowers, door handles etc.

The basic tig pieces of equipment that are used in TIG welding are:

  • Tungsten electrode.
  • Welding machine
  • Torch or electrode holder.
  • Shielding gas supply (helium, argon or mixture): argon better for thinner metals due to lower heat requirement.
  • Filler metal rod.
  • Personal safety equipment.

These are the basic TIG equipment that is used. That is mentioned above.

Similarities between MIG and TIG welding:

The common similarities that are used in both the MIG and TIG welding. They are mentioned below:

Both the TIG and MIG welding which is basically an arc welding process as an electric arc which is constituted between the electrode and also the base plate to meltdown in the process and also to faying surfaces.

Both the processes also utilize the electrode. Although the electrode material is different in the processes.

It is said that in both cases, shielding gas is also required to supply from the additional sources. This is unlike MMAW or FCAW process in which the shielding gas is obtained during the process.

The Inert shielding gas is used in both the areas which protects the hot weld from oxidation and also contamination. The only inert gases like argon, helium, nitrogen, or also a mixture of such gases are used.

The only conductive metals that can be joined is only by these two processes. The arc welding process is only applicable to conductive metals only. The solid-state of welding can be applied for the joining non-conductive metals.

These are the common similarities in both the TIG and MIG welding is mentioned above.

Difference between mig and tig welding:

The few difference between the TIG and MIG welding are mentioned below:

1. The metal inert gas (MIG) welding will utilize the consumable electrode which is continuously fed into the welding zone from the wire pool whereas TIG welding utilizes a non-consumable electrode.

2. The electrode which melts down to the supply filler metal and also required to fill the root gap between the base metals, so that the electrode acts as a filler metal and in TIG the filler metal is the one where it is supplied additionally by feeding the small diameter rod into the ar.

3.  It is also mentioned that in the MIG is the composition of the electrode metal which is selected based on the parent metal. And also mentioned that the metallurgical composition of the electrode metal is similar to that of the base metal whereas in TIG the electrode is always made of the tungsten with the small proportion of the other metals.

4.  It is clearly mentioned that the MIG is suitable for homogeneous welding. It cannot be carried out in the autogenous mode welding whereas the TIG is particularly suitable for autogenous mode welding. But also it can be employed for the homogenous or heterogenous or also in both modes which supply the additional filter.

5. In the MIG welding, the electrode filler varies in the form of small diameter (0.5-2 mm) and also it is very long whereas the TIG welding filler which also comes in the form of small diameter (1-3 mm) and also the short length rod.

6. It is also mentioned that in MIG, due to the large length, the filler electrode can be fed for a longer duration without any replacement but in TIG due to the short length, the frequent replacement of the filler is also required. This one interrupts the welding process unintentionally.

7. MIG welding is commonly carried out in AC or in DCEP polarity so that the electrode can be melted easily at the faster rate whereas TIG welding is commonly carried out in AC or DCEN polarity in the electrode

8. In MIG, the filler deposition the rate is very high so that the process is highly productive whereas in TIG the filler deposition rate is low and it is not productive.

9. In MIG welding, they usually produce the spatter. This will cause a loss of costly filler metal. Whereas TIG welding is mostly free from the spatter.

10. In MIG welding, the quality and the appearance of the weld bead are not very good whereas the TIG welding, it can easily produce a defect-free reliable joint with the good-appearance.

11. It doesn’t lead to tungsten inclusion effect and the TIG welding sometimes leads to the tungsten inclusion defect ( Which occurred when a melted part of the TIG electrode gets embedded into the weld bead.

12. The TIG welds are well known for its thinner metals and also the smaller projects as they produce control of the clean weld. The TIG welders need to have a better experience with the timing and also the balancing of the materials. The MIG is easier to control and also the better for the beginners.

13. The main, important and the largest difference in the welding gloves is that the distinctions between the gloves that are used for both TIG and MIG welding. The MIG gloves wish to fit in the looser way and also have the extra padding on the backside of the hand whereas the MIG gloves offer better protection in your whole hand. The TIG gloves are also made of the much thinner and softer material.

14. The MIG welding is a heavy-duty which is suitable for the welding work, whereas TIG welding works for joining the smaller pieces of metal. Also with the robotic welding equipment, The TIG welding can be of a lower experience etc..

These are the main and the better difference that is differentiated in TIG and MIG welding is mentioned above.
