PLASMA
Precise welding also for thick materials!
Our Plasma Welding Processes
Plasma welding is particularly beneficial in applications where high welding speeds, deep penetration, and minimal heat-affected zones are required. It is commonly used in industries such as aerospace, automotive, and manufacturing, where precise and high-quality welds are crucial. By enabling keyhole welds and offering better control over the welding process, plasma welding by OTC provides an advanced solution for achieving accurate and reliable welds in thin and thick materials.
Multilayer TIG vs. Plasma Welding
During plasma welding, an electric arc is established between the tungsten electrode and the workpiece. The arc passes through a copper nozzle, which constricts and shapes the plasma gas flow. The plasma gas, typically argon or a mixture of argon and hydrogen, is introduced through the nozzle to create a highly concentrated and stable arc.
Key Advantage of OTC Plasma Welding with Pilot Gas
The key advantage of plasma welding is its ability to achieve deep penetration and narrow welds, known as keyhole welds. The intense heat generated by the plasma arc creates a keyhole or narrow cavity in the molten pool, allowing for efficient fusion between the base metal and filler material. This results in strong and precise welds in both thin and thick materials.
We invite you to explore specialized robotized welding techniques, including:
OTC DAIHEN’s dynamic welding process combines high melting rates with low heat input, enabling the welding of steel, galvanized and stainless steel, as well as aluminum down to a thickness of 0.6 mm.
OTC DAIHEN’s alternating current welding process utilizes electromagnetic forces (pinch effect) to form and control weld droplets. This method is ideal for welding thin materials at high speeds and for tackling challenging gap bridging.
OTC DAIHEN’s improved alternative for tandem or double-wire welding solutions. It offers extremely high deposition rates with flexible weld routing, all with a single wire.
