4 Different Types Of Welding Processes


Welding processes: – Welding is a fabrication process used to joins both metals and other materials at their molecular level with the technology we have At the same moment it is a simple process that the industrial revolutions needed and without many of the things, for as granted would not be here, Almost any industry or every industry, from underwater construction to space explorations.

So, right now how many things around you are made of metal? If yes then it’s made of metal there is a good chance it was welded.

Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering the most common welding processes welding today has 5 different types that are in following.

Tig welding:

Tungsten arc welding / a torch that has a gas flowing through it with a non-consumable rod made of the tungsten those heats. Tig welding, also known as gas tungsten arc welding [GTAW]. Tig has played a major role in the acceptance of tig welding aluminum for high-quality welding and structural application.

Tig welder: – Tig welder can be used to weld steel stainless, steel Chromoly, nickel alloys, and even gold. Tig is a useful welding process for welding wagons, bike frames, door handles, and more to create high-quality, clean welds, with superior arc and welds when appearances count.

Gas tungsten arc welding (GTAW):

 [GTAW] process the arc is formed between a pointed tungsten electrode and the workpiece is an inert atmosphere of argon or helium, Tig welding must be operated with a drooping, constant current power source either DC or AC. Current being drawn when the electrode is short circulated onto the work pc surface.

Tig welding machine mainly consists of this instrument are welding power supply, welding torch gas cylinder, and gas flow controller. The polarity of the electric current (positive or negative) should be selected depending on the base material. Tig welding can be classified according to the use of AC or DC power, the use of pulse or non-pulsed current, and whether a filler wire is used or not.

There are two types of tig welding that use a filler wire: Cold wire welding and not wire welding. Cold wire welding heats up the wire beforehand by passing a current through it. This can increase the amount of deposition per unit time.

Mig welding:

Metal inert gas welding, MIG is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. The two base materials are melted together forming a join. The electrode helps protect the weld pool from air-bone contaminants. Mig welding is often referred to as a semi-automatic process, as the wise feed rate and arc length are controlled by the power source. But the travel speed and wise position are under manual control.

The process can also be mechanized when all the process parameters are not directly controlled by welders but might still require manual adjustment during welding, when no manual intervention is needed during welding, the process can be referred to as automation.

Flux cored arc welding (FCWA):

(FCAW) is a semi-automatic arc welding process. (FCAW) uses a continuous wire-fed electrode, a constant voltage–welding power supply.  The (FCWA) welding technique provides several advantages over other methods.

Tig welders for money:-  For aluminum, titanium or this sheet, heat control is key.

The two handed method is  also the most rewarding to master.

Tig machine carries quite a price of you’re un sure what you really need.

Crowd machines to  find the tig welder.

  1. Yes welder tig – 250 p AC/DC tig aluminium
  2. Eastwood tig 200 AC/DC  tig welder
  3. Prime weld tig 225x AC/DC tig welder
  4. Lincoln electric 200 AC/DC tig welder
  5. Miller  electronic max star tig welder
  6. ESAB  rebel 215 IC DC  tig welder

Tig welding is a big step up from basic welding skills, and tig machines cost a lot more than other welders.

Conclusion: – Welding is today the most common used method of joining components in the fabrications of complex structures. If the structure is to perform satisfactory, the integrity of the welded joints must be good as the materials being joined. Welding encompasses many scientific disciplines. It involves a complex interplay of solid, liquid and plasma state phenomena.

Welding process has improved many sectors and their advantages have made welding a growing industry.
