What is MIG Welding?

Metal Inert Gas welding (MIG) is also known as GMAW (Gas Metal arc Welding. In this welding process the metal is the referred to a wire used to start the ARC. The feeding wire act as filler rod and is shielded by Inert gas. A spool supplies the wire electrode through a welding torch connected to the positive terminal in the welding zone.
MIG welding is used for welding of all thickness of steel, aluminium, nickel, stainless steel etc and for continuous welding.
In MIG welding process DC arc burns between a work piece and a thin bare metal wire electrode.
Most of MIG welding processes operate on DC with reverse polarity.

Pros

  • Much faster high quality weld can be produced.
  • No Slag entrapment due to no use of flux
  • No alloying elements losses since gas shield the arc.
  • MIG welding can be used with various metals and alloys.
  • MIG process can operate as semi and fully automatic.

Cons

  • Due to the High heat input and the fluidity of weld puddle, MIG welding can’t be used in vertical or overhead positions.
  • The equipment is compound type

What is TIG welding?

Tungsten inert Gas (TIG) is also known as Gas Tungsten Arc welding.TIG welding is an arc welding process that produces the weld with non-consumable Tungsten electrode.
The arc is produced between the pointed Tungsten electrode and the job in an inert atmosphere of argon or helium.
For the high quality precision welding, the small intense arc produced by the ideal pointed electrode.
Balance of heat input is not required since there is no consumption of electrode. Separate filler is added separately in the event of the requirement of filler metal.
Drooping constant current power source ( DC or AC) is required for the TIG welding.

Pros

  • Heat and amperage can be controlled with a remote control or foot thumb
  • Good for the projects require detailed design and curves on the base metal.
  • Due to the low amperage usage, this process works well on thin metal piece
  • Operator can switch over quickly from thin metal to thick metal due to the low amperage and remote control switch.
  • Weld is clean and slag free.

Cons

  • TIG welding requires high level of patience and skill due to the time consuming process
  • TIG welding requires high level of focus and hand-eye coordination.

What is an Inverter Welding machine? 

A machine that uses sophisticated silicon technology compared to the traditional welding machine using copper or aluminum transformers is known as an inverter welding machine.

An inverter welder, an electronic system, is used for voltage regulation by controlling the AC power supply to the lower output voltage. Usually, an inverter welder converts 240 V Ac power supply to 20 V DC output.

The traditional transformer-based welder uses a single transformer to regulate the voltage.

An inverter welder functions with the increased frequency from 20,000 HZ to 100,000Hz with the help of electronic switches.

Applications of Inverter welder machine

For the welding of stainless steel and iron metals, an inverter welder is the most suitable machine. This machine is popularly and conveniently used for the welding of domestic items, construction, and industries.

Advantages & Disadvantages of Inverter welder machine

Advantages

  1. Size & Weight;- Weight and size are the important and attractive advantages over conventional welding machines. Being lightweight and portable an inverter welder can perform the job of a 50 Kg conventional welding machine.
  2. Efficiency;- Most of the inverter welders have an efficiency of 80to 90 % in comparison to the conventional welders having an efficiency of 50 %. Losses in conventional welding machines are more than the Inverter welder is due to the resistance losses in heavy transformers.
  3. Use of Generator Power;- it is viable to operate the inverter welders on portable generator power without any risk. The conventional power can’t operate on portable generators due to the risk involved.
  4. Duty Cycle; – Due to the difference in transformer size of Inverter welders and conventional welding machine, the duty cycle of inverter welders are much higher. But the smaller components get heated up soon in inverter welders, which can be easily cooled.
  5. DC Output;– In inverter welders, the rectification of current into DC is much easier, and a wide range of different types of the electrode can be used. In conventional types, welders have only AC power and the choice of using a different type of electrode is limited.
  6. Performance;– The performance of Inverter welders is remarkably superior to the conventional welders. Superior performance is possible due to the ability of the inverter machine to have higher open-circuit voltage and functions of hot start, Anti-stick, and Arc-force are incorporated.
  7. Functions;– Functions in inverter welder are controllable due to the electronics of the machine and ability to incorporate the additional functions.

Disadvantages

  1. Price;- Due to the involvement of sophisticated components like pulse transformers, Condensers, Controller boards, fans, and radiators, the cost of an Inverter welder will be higher than the conventional welders. But due to the sophisticated electronic components, the inverter welders are more reliable and involve high-quality output.
  2. Care & Maintenance;-  Inverter welders contain sophisticated printed circuit boards and small power components. These sophisticated components need utmost care against the pollution environment containing dust and moisture. Inverter welder needs to be cleaned regularly from inside to remove dust and protection from moisture. If due to some reasons the inverter fails, then the repair will be costly, since the high-quality electronic components are expensive especially IGBTS and high-speed diodes.

What is IGBT Inverter technology?

IGBT stands for “Insulated Gate Bipolar Transistors. World-class Inverter uses these high-speed switching devices to control the Voltage regulations. IGBT technology provides more significant features than the old MOSFET (metal-oxide-semiconductor field-effect transistor) technology. IGBT technology is not vulnerable to main and generator power supply.

Welding is joining metals by using the heat to melt the parts together, cooling due to fusion.

  • MIG- In Metal Inert Gas, continuous solid wire is heated and supplied to the welding process with the help of a welding torch.
  • TIG- Tungsten Inert Gas welding is the welding process in which the joining of metals is performed by heating with an arc between parent metal and tungsten electrode.
  • Stick & Flux- A welding rod and electricity are used in the stick and flux welding process.
  • Cored Arc welding In this process, electric is a continuous filler metal electrode with the parent metal.

Flux is used to protect the welded area from getting contaminated by gases present in the atmosphere. Carbon and manganese are the elements of flux.
