Different Types of Welding Techniques 2022

types of welding

Welding is a process where two metallic or non-metallic pieces are joined by means of high energy, as long as they are of the same or similar composition so that the joint remains rigid. We will choose the type of welding depending on the physical properties of the metals, the use to which the welded piece will be destined, and the facilities. Our guide to welding has a bit of information on types of welding:

Different Types of Welding Techniques in 2022

SOFT WELDING

SOFT WELDING:

This type of solder is used to create joints in tinplate, galvanized sheets, brass and bronze parts, lead pipes, and electrical components.

In this type of welding, the temperature used is below 450 degrees Celsius, and an electric soldering iron is used.

STRONG WELDING

STRONG WELDING:

It is a technique of thermal union, with which it will obtain connections of brass, copper, silver alloys, and steel.

The temperature ranges from 450 to 800 degrees Celsius, and a gas torch is used.

OXYACEYLENE WELDING

OXY ACETYLENE WELDING:

It is used for iron or steel sheet applications, mostly in use in the marine, construction, and automotive industries.

It is welded at a temperature higher than 3000 degrees Celsius, and an Oxyacetylene torch is used.

ELECTRIC RESISTANCE WELDING

ELECTRIC RESISTANCE WELDING:

It is of great importance in modern industry, especially in sheet metal.

This welding technique is used for the manufacture of car bodies, electrical appliances, and in the electrical and toy industries.

The metals are joined without the need for filler material; only pressure an

 

d electric current are necessary on the areas to be welded.

ENERGY BEAM WELDING

 

ENERGY BEAM WELDING:

It is the most modern welding technique. In this type of welding the laser helps to weld materials with a high melting temperature, exceeding 5500 degrees Celsius.

It even joins those materials that could not be welded in any other way.

It is a very fast and highly productive welding process.

MIG Welding

MIG welding is among the easier types of welding for beginners to study. it’s good welding contains two different types of welding. The first uses bare wire and the second incorporates flux.

Bare MIG welding can be used to weld thin pieces of metal together. Flux core MIG welding can be used outdoors because it doesn’t require a flow meter or a gas tank. MIG welding is the welding of choice for DIY enthusiasts and hobby welders who don’t have the cash to spend money on expensive equipment.

Stick Welding

The Stick welding, also known as Arc welding, is doing it the old-fashioned way. Stick welding is a bit harder to master than MIG welding, but you can pick up a stick welding equipment for very little if you want to give it a go at home. Stick welding uses a stick electrode welding rod. The below video explains the differences of Wire Feed Welding and Stick Welding.

TIG types of Welding

When used properly, TIG welding is extremely versatile and difficult to learn, but Lincoln Electric TIG welders are professionals that require extensive training and experience.

TIG welding requires the use of both hands. One holds a rod while the other utilizes an alternating-current TIG torch. This torch generates heat and arc, which are used for most conventional metals, including aluminum, steel, nickel alloys, copper alloys, cobalt, and titanium.

TIG welders can be used to weld just a few of these materials, including steel, stainless steel, chromoly, aluminum, nickel alloys, magnesium, copper, brass, bronze, and gold. TIG is a useful method for welding bike frames, lawn mowers, handles, fenders, and other devices.

Plasma Arc types of Welding

Plasma arc welding is an extremely precise technique and is employed specifically in aerospace applications where metal thickness is below 0.015 inches. One of the many applications is in an engine blade or an air seal. Plasma arc welding is comparable to TIG welding, but the electrode is recessed and the ionizing gases within the arc are used to generate heat.

The regular complement of gasses is argon for plasma gas, with argon plus two to five hydrogens for shielding gas. Helium can be used for plasma gas, but as it is colder, this lowers the rating of the flow nozzle.

Electron Beam and Laser Welding

The Electron beams and lasers provide extremely accurate, high-energy electromagnetic welding techniques. Electron beams and lasers can be directed and polished with pinpoint accuracy to weld the tiniest of medical devices, while also enabling large spacecraft parts to be welded with great amounts of power. Electron beam and laser welding have the possibility of being used for a wide variety of objects. Both processes are cost-effective and can produce gorgeous welds from an aesthetical and metallurgical point of view.

Gas types of Welding

The Gas welding, which has been supplanted by TIG welding, isn’t used as much anymore. GAS welding equipment generally runs on oxygen and acetylene and is very portable. However, these machines are still sometimes utilized to weld parts of car exhaust back together.

The US and the world suffer from a shortage of experienced welders. Many young people are taking the welding specialist occupation due to the many opportunities it has.
