What Are The Different Types Of Welding?

If salary is a good indicator of a successful career, being a welder is probably one of the most highly valued blue-collar jobs out there. As a matter of fact, an underwater welder can earn as much as $300,000 per year, exclusive of the chance to travel around the world and meet interesting people.

But before you reach this stage, you need to gain expertise in the field and prove your reputation. Above all, you should go to an accredited welding school or facility. To get into either of these, you need to have at least a high school diploma or equivalent.

One of the things you’ll be taught in school is of course the fundamentals, particularly on the different types of welding. You’ll be given not only a theoretical background on this subject, but you will also be provided with ample hands-on activities to ensure that you’ll gain full mastery of your craft.

What are the different kinds of welding?

The types vary depending on what source you use. While others say there are at least 100 types of welding that include even those not used on a commercial scale, others stick to the more general classifications, which this article contains.

  • arc weldingArc WeldingMost sources agree that arc welding is the most popular of the welding types. And this comes with several reasons. For one, it is not as costly as the others; second, the metal to be welded does not need to be clean; and third, you can use this outdoors even in unfavorable weather conditions.Through the years, arc welding has spawned several categories such as gas metal arc welding, plasma arc welding, and shielded-metal arc welding.Shielded-metal arc welding is sometimes called “stick” welding, so-called because a welding stick is inserted into the equipment. Though this is inexpensive, stick welding has disadvantages. It leaves splatters on the floor, for instance, so you’ll need constant maintenance to make your workplace clean. Also, the splatter can scald your skin.
  • TIG weldingTungsten Inert Gas Welding (TIG)As what its name implies, TIG uses a tungsten electrode to create an electric arc, which produces the heat necessary for the welding process to commence. One of the unique qualities of tungsten is that it has a high melting point. Because of this, it doesn’t melt easily as compared with other metals and that a special filler needs to be connected to a special filler to make the welding device work.TIG welding is a versatile welding process. It works for kitchen equipment, aircraft parts, gas turbines, boat components, and many others. That is why it is a favorite of many industries such as the aerospace and nuclear industries, and companies that work with stainless steel.
  • MIG weldingMetal Inert Gas Welding (MIG)MIG welding is a process that makes use of a gas to shield the welded metal against environmental elements that can slow down the process. Oxygen, for instance, can hinder the welding process, but if an inert gas is used to shield the metal against it, the welder can finish the job in no time.However, MIG welding requires a high skill level, and it must only be used indoors.
