Flanges with different welding methods

Mar 21, 2019

The term "welding" refers to the bonding of materials, such as thermoplastics or metals, to connect them seamlessly. Welding involves applying pressure and heat to the material being joined and to the filler material, which forms a cooling pool and forms a very strong joint.

Over the years, welding techniques have evolved a lot, and now there are many different welding techniques. You need to choose the right one for the job at hand to produce the best results. Let's look at different types of welding.

Arc welding

When arc welding, the electrode and power supply are needed to make the welding arc between the material being welded and the electrode. This melts the material, cools it down and fuses it together. This welding process is the most popular and includes the three most common types of welding - rod, TIG and MIG. There are non-consumable and self-consumable electrode methods.

Nowadays, rod welding is very old. It is a manual form of welding that relies on a consumable electrode and is coated with a helpful flux before being used to lay down the weld.  

This process is called rod welding because it USES a electrode or rod made of flux and filler material. The flux protects the molten metal of the weld when the solder joins the metal parts together. Rod welding is economical and requires very little equipment. Unfortunately, the final weld quality is not always perfect, as it can be shallow penetrable, porous, susceptible to severe weather, and reduced in durability and cracking. Welding technology is still used in automobiles, buildings, pipelines and refrigeration.

MIG welding

This type of welding is also popular. MIG welding represents metal inert gas welding in which two pieces of metal are combined using a wire connected to the electrode current. The wire passes through a electrode shielded by inert gas. One of the advantages of MIG welding over different welding technologies is its user friendliness and the low accuracy required by the operator for proper welding. MIG welding is more sensitive to wind, dust, rain and other external factors. In addition, the operator needs to find a way to adjust the line speed and voltage. It is a popular welding in automobile maintenance because, if done correctly, it can provide rugged, rugged welding.

Flux-cored wire

Similar to MIG Welding, Flux Cored Arc Welding USES tubular Welding wires filled with Flux. This type of welding shielding gas is not always required, depending on the packing used. For starters, cartridge welding is easy to learn and very affordable, even if the results are not always pretty.

Submerged arc welding

Usually used in nickel-based and ferrous metal alloys, submerged arc welding is popular due to its minimal smoke emission. With minimal preparation, it can achieve deep welding, making it efficient and fast.

TIG welding

Tungsten inert gas arc welding is a non-consumable technology that USES argon to produce high quality, strong welds. This form of welding generates heat by passing an electric current through the tungsten electrode. TIG is suitable for a variety of applications and is commonly used for welding stainless steel as well as copper, nickel, aluminum and magnesium.

Electroslag welding

This is an efficient welding process usually used for non - ferrous thick materials. It is a complex technology that requires many skills and is often used in the aerospace and Marine industries.

Gas welding

This is a very old technique, also known as oxyacetylene welding. It may be old, but today it is still used for piping and pipe welding.

Solid-state welding

This form of welding is produced by using temperatures below the melting point of the material and without filler. Pressure, time and temperature each play key roles in joining metals without significantly melting them.

There are many different types of welding. Different types of welding require different types of welding equipment. Knowing which is best for each project is key to maximizing welding success.
