Welders can shape some of the strongest materials in the world into the items they imagine, thanks to welding techniques. The following welding processes are utilized in particular industrial sectors.
Electroslag (ESW) Welding
Industries like shipbuilding, energy production, and petrochemical applications use industrial welding techniques. The employment of the electroslag welding technique allows for the vertical joining of thin metal plates edge to edge. It takes place between the margins of the two plates instead of applying the weld to the exterior of a joint.
The two plates are positioned for connection using disposable metal guides sandwiched between them. This guide allows the passage of a copper electrode, the joint filler. Applying electrical current causes the arc to form. The intended weld region slowly becomes covered in welding as it begins at the seam’s beginning.
After the initial setup of the plates and guides, the movement is controlled by a machine, and the operation is automated. The primary application of electro slag welding is to join very thick low-carbon steel plates. It can also be applied to structural steel if proper safety precautions are taken. ESW uses slag conduction to carry the welding current.
Laser Beam Welding (LBW)
Metals and thermoplastics both accept this kind of welding. As the name suggests, it entails using a laser as a heat source to form the welds. It applies to titanium, aluminum, and high-strength low-alloy (HSLA) steels, including DOCOL®, stainless steel, carbon steel, and high-strength steels. Robotic automation makes it simple to automate, which makes it popular in production, including the following areas:
- Automobile Sector
- Industrial Welding
- Electronics Industry Welding
- Medical Welding
- Aerospace Welding
- Energy Industry Welding
Laser welding techniques and applications are most prevalent in the automotive industry since lasers increase productivity cheaply when joining vehicle parts, such as roof, door, or filler assemblies.
Plasma Arc Welding (PAW)
Plasma arc welding is a fantastic option for applications involving fragile computer components because it can operate in a very low current mode. It uses a smaller arc and lower voltages to improve the weld’s accuracy. With such precision and voltage, it is possible to build delicate and heat-sensitive products, including microchips and medical equipment.
In addition, the torch may reach extremely high temperatures in constrained areas. The wand creates plasma by pressurizing gas inside of it. Ionization occurs next, turning the plasma into something that conducts electricity.
This enables the formation of the arc, which generates extremely high temperatures capable of melting the base metals. It makes it possible to do plasma arc welding without using any filler metal equivalent to TIG welding.
Applications involving fragile computer components benefit greatly from PAW’s ability to operate in a very low current mode. Low current is beneficial since electronic devices might be sensitive to environmental elements like excessive heat. While GTAW is occasionally an option, experts from Micro Weld, Inc advise that plasma arc welding is the best option for the highest level of precision. The following are some uses for it:
- Steel tubing in the automotive sector
- The joining of thin electronic chips
- Manufacturing of medical devices
- Small metal component welding

Choosing the right type of welding technique is vital to manufacture perfect products.
