Welding is a process, where metals and thermoplastics are being joined by applying heat with or without pressure. Steel, iron, aluminum, copper, copper alloys, nickel are being joined in welding process. Welding is performed in different environments like in open air, under water and in outer space.

Welding is done from different energy sources like gas flame, electric arc, laser, electron beam, friction and ultrasound, among all Electric Arc is widely used.

More than thirty types welding processes are existed but only the below methods are commonly applied:-

Mig (Metal Inert Gas) Welding process is used to weld carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon, bronze and other alloys. Mig welding has the ability to join most type of metals with different thickness and it can be performed in most positions. This is a popular arc welding method for thin sheets and sections.

It is important to pay attention during welding to avoid electric shock, burns, vision damage, inhalation of poisonous gases and ultra violet radiation.

Consumable Metal Rod is used in MIG welding as electrode. Mig welder can weld mild steel, stainless steel, and aluminum. Electrode feed is required continuously in MIG welding. Mig welding is too powerful for aluminum but not enough powerful for cast iron. Mig welding is also known as Gas Metal Arc Welding (GMAW) and Metal Active Arc Welding (MAGW).

Tig (Tungsten Inert Gas) welding is also known as Gas Tungsten Arc Welding (GTAW). In Tig welding non-consumable electrode (Usually tungsten) rod is used. It requires inert gas (Argon/Helium) and filler rod of similar composition of the parent material. This process is bit newer to the welders. Tig provides high quality welding. Many industries like aerospace, bicycle factory use Tig Welding Process to join pipes and weld tubes of small diameter and thin wall. Tig welding process is free of weld splatter and its distortion is low.

To keep safe from electric shock the welders use welding helmet, rubber boots, and rubber gloves under welding gloves.

Stick Welding

Plasma Arc Welding (PAW): This process uses ionized gases and electrodes that create hot plasma jets amid the welding area. This is better for narrow, deep and speedy wedding.

Flux Cored Arc welding (FCAW) process uses tubular electrodes that are filled with flux. It has a higher weld-metal deposition rate that is ideal for welding dense sections.

Shielded Metal arc Welding (SMAW): The SMAW process is simple, old and adaptable. The arc is made when the electrodes get touch welding area. This arc welding process is used in pipeline, shipbuilding and construction.

Submerged Arc Welding (SAW): This process functions with granular flux that creates a thick layer during welding. You will get no sparks and spatter here. It works like thermal insulators. SAW process is used for high speed sheet and plate steel welding and limited for horizontal welds. 

Advantages of TIG Welding:

  1. Because of superior arc and controlled foot puddle system Tig welding creates high quality and clean work, where no further cleaning is required. The welder can increase or decrease the heat according to his requirement by using the foot pedal.
  2. Tig welding process is free of weld splatter and its distortion is low.
  3. Shielding gas in Tig welding protects the weld and tungsten.
  4. Tig produces high quality and clean welding.
  5. Tig welding welds more metals than any other welding process. This process can weld steel, stainless steel, chromoly, aluminum, nickel alloys, magnesium, copper brass, bronze, and gold.
  6. It may be done in all positions- flat, horizontal, vertical and overhead.
  7. One can easily operate this machine both manual and automatic.
  8. Welding may be done by applying less amount of heat.
  9. Thin materials are welded in this process.

Disadvantages of TIG Welding:

  1. This process is suitable for thick materials.
  2. It takes more times to weld.
  3. It is required high initial cost.

Why should you choose TIG Welder:

For joining thin pieces of metals and fancy works Tig Welding machine is used. Initial investment against Tig welding is something high but during welding your cost will be less.

Selection of right TIG  Welder: 

You will choose your welder based on your purpose. From that point of view first, you will see that you are an amateur or a professional. If you are an amateur you will select your welder considering the factors like weight, length, width, portability, welding position, welding materials, the thickness of the material, power source, welding quality, after-sales service, longevity, warranty and price. Detailed information of some welders of the latest and renowned companies has been shown in the above table, from where you can select your right product considering the points. A professional welder also searches pulsed welding, foot pedal, high-frequency settings, simple controls, versatility, cooling torch, arc quality, operating system (manually, robotic) in addition to above factors.

Welding Terminology:


The physical gap between the end of the electrode and the base metal. The physical gap causes heat due to resistance of current flow and arc rays. An arc is a sustained electric discharge through this ionized gas column called plasma between the two electrodes.


Tungsten is a heavy metal more than 2.5 times than steel, its melting point is 3422C. The temperature during welding of tungsten electrode reaches at 33250 C which is closer to the melting point of tungsten.


Substance that is used to remove or prevent the formation of undesirable oxide and other substances during welding.


Flux is the substance added to the molten metals to bond with impurities that can be readily removed.

Welding torch

Welding torch is a part of welding apparatus. It conducts electric current to the electrode and carries the shielding gas to the arc zone. It serves to adjust the mixture of gases and guide the welding flame during gas welding like Tig welding and Mig welding. 

Shielding gas

Shielding gas protects the welding area from oxygen and water vapor. This is inert or semi-inert gases that are commonly used several welding processes most commonly in Tig and Mig welding.    

Foot pedal                               :

Earth clamp

Earth clamp is a metal strip that connects the lead out cable of energiser to an earth rod like water pipe. It guarantees a secure connection between the energiser and earthing system for optimum electrical connectivity.


Frequency is expressed in cycles per second, or Hz [The hertz (Hz) is the derived unit of frequency].

Auto compensated

Automatic Compensation Scheme means customers will get the money back from their provider when things go wrong, without having to ask for it.

Power Efficiency

Power efficiency is expressed in percentage. Power efficiency 80% means, the output is 80% of input. 

Duty cycle

A 60% duty cycle is a signal that is ON 60% of the time and OFF the other 40%. For example, a 150 amp. welder with a 30% duty cycle must be "rested" for at least 7 minutes after 3 minutes of continuous welding.


Ampere is a measuring unit of the rate of electron flow or current in an electrical conductor. The measurement of the amount of electricity flowing past a given point in a conductor per second. Current is another name for amperage.

One ampere = One coulomb of charge flowing per second.
One coulomb = 6.24 X 1018 electrons each second


Ampere is a measuring unit of the flow of current in an electrical conductor. Current is a count of the number of electrons flowing through a circuit. One ampere is the amount of current produced by a force of one volt acting through the resistance of one Ohm.

Dual voltage

A dual voltage device can accept 110-120 volt and 220-240 volt. Dual Voltage Input means you can plug into any common power supply. If you see something on the power label that looks like 110V AC or 120V AC, that is a single voltage device.

Stainless Steel

Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.

Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced form-ability and increased corrosion resistance.

Frequently Asked Questions

1. How we can clean the base metal?
Ans: It is important to clean the base metal and keep from contamination including dirt, paint, and oil. Wipe the metal by cloths or scrap. 

2. What are causes of unstable arc?
Ans: Due to the wrong size of tungsten that means if the tungsten is too large for the amperage the arc will rotate around the end of the tungsten. Conversely if the tungsten is too small for the amperage the current can melt the metal resulting to an erratic Arc.

3. Which current AC or DC is better for Tig welding?
Ans: AC (Alternate Current) is best for Tig Welding and DC is best for Mig Welding.

4. What are the precautionary measures for Tig Welding?
Ans: Clean your welder before starting welding to avoid inhibition of components. In case of Direct Current the welder should be manual and AC welder to be with reduced open circuit voltage. Flammable materials should be moved from welding area. Personal protections like goggles, fire proof protective cloths, face & head mask, globes wearing to be ensured.
