PLASMA WELDING
Plasma welding, also known as plasma arc welding (PAW), is a type of gas tungsten arc welding (GTAW) that’s highly regarded for its superior welds and clean finishes. Plasma welding allows for extremely high-temperature welds to be performed under high levels of control, ensuring it’s a popular welding choice amongst a number of industries worldwide.
Plasma welding is a process that can be fully automated using a robotic plasma welding machine, and integrated into wider robotic systems and manufacturing processes. Cyber-Weld provides clients with bespoke plasma welding solutions designed to meet industrial requirements.
What Is Plasma Welding?
Plasma welding is very similar to other types of gas tungsten arc welding, including tungsten inert gas (TIG) welding. Like TIG welding, plasma welding uses a non-consumable tungsten electrode in order to create a weld pool that can fuse metals together. Plasma welding requires two inert gases to work: the first creates the plasma, and the second is used as a shielding gas.
The tungsten electrode is built into the welding torch, and the first inert gas is fed through this same nozzle to create the plasma. A second inert gas is then used as a shielding gas in order to protect the weld pool from contamination and create a smooth finish.
The unique design of a plasma welding machine enables the first gas to build up inside the nozzle while remaining completely separate from the shielding gas. This means that the electric arc produced by the electrode can turn the first gas into plasma after reaching extremely high temperatures. The plasma is forced out through the nozzle, where it creates the necessary weld pool while being shielded by the second inert gas.
What Types Of Plasma Welding Are There?
There are several different types of plasma welding that can be utilised in an industrial setting and integrated into automated production and manufacturing systems. The most common types of plasma welding include:
- Microplasma welding: specifically designed for welding extremely thin sheets of metal together.
- Medium current welding: uses a medium current to weld together thicker pieces of metal.
- Keyhole welding: the most powerful type of plasma welding, used to weld together the thickest sheets of metal.
What Is Plasma Welding Used For?
Plasma welding is an incredibly versatile form of arc welding. Compared to other types of welding, including similar TIG welding processes, plasma welding allows the user to create a much smoother finish and produce a higher quality product.
Much of this is due to the increased level of control that a plasma welding machine caters for. Because the electrode is built into the welding torch, high temperatures can be maintained without any loss of control. This means that thicker pieces of sheet metal can be welded together. This ability to create high temperatures under controlled conditions means that plasma welding is commonly used to weld thick, tough metal together.
Equally, plasma welding is well suited to welding thinner, trickier-to-weld metals such as aluminium. Plasma welding machines can be easily adjusted to change the current, temperature, gas flow, and more, meaning the process can be applied to a wide range of metals and processes. Importantly, the plasma welding process can easily be automated with the use of robotic systems.
Why Choose Robotic Plasma Welding?
Plasma welding is well suited for automation, and robotic plasma welding machines can be integrated into wider robotic systems, production lines, or assembly and manufacturing processes. There are a number of clear benefits to choosing robotic plasma welding over manual plasma welding, including:
- Improved accuracy and precision
- Consistent, high-quality welds and finishes
- Ability to operate 24/7
- Cost and time savings
- Improved health and safety standards
