In the world of welding tables, durability, precision, and longevity are key to producing high-quality results. One of the standout features that distinguishes Siegmund welding tables from others in the industry is their use of plasma nitriding, a process that enhances the surface of the steel, making it harder, more durable, and resistant to corrosion and wear. But what exactly is plasma nitriding, and why does it make such a big difference in the performance of Siegmund tables?

In this blog, we’ll dive into what plasma nitriding is and why it’s a game-changer for welders and fabricators who rely on the durability and accuracy of their work surfaces.

1. What is Plasma Nitriding?

Plasma nitriding is a thermochemical process that hardens the surface of steel by diffusing nitrogen into it. In this process, the steel is placed in a vacuum chamber, and a plasma field is generated using high-voltage electric discharges. This plasma causes nitrogen ions to penetrate the surface of the steel, creating a hard, wear-resistant layer.

The result is a surface with increased hardness and resistance to wear and corrosion, all while maintaining the core material’s toughness. This makes plasma nitrided surfaces ideal for welding and other heavy-duty industrial applications where both durability and precision are essential.

2. How Plasma Nitriding Benefits Siegmund Welding Tables

Siegmund tables are designed to withstand the most demanding environments, and the plasma nitriding process plays a huge role in achieving this. Here are the key benefits plasma nitriding brings to Siegmund welding tables:

• Surface Hardness: Plasma nitriding enhances the surface hardness of Siegmund tables. Many tables in the Siegmund lineup reach up to 63 HRC, while the PLUS series tables reach an incredible 66 HRC. This makes the table surfaces extremely resistant to dents, scratches, and other forms of damage.

• Corrosion Resistance: In combination with the BAR (Black Anti-Rust) coating, the nitrided layer provides excellent resistance to corrosion. Even in environments exposed to moisture, humidity, or harsh chemicals, the plasma nitrided surface maintains its integrity, reducing the likelihood of rust or degradation.

• Improved Welding Spatter Resistance: Plasma nitrided surfaces are also highly resistant to welding spatter. Spatter from welding tends to stick to untreated steel surfaces, making cleanup difficult. With a plasma nitrided Siegmund table, the spatter is less likely to adhere, reducing the need for abrasive cleaning methods that could damage the table.

• Reduced Wear: Whether you’re frequently clamping down materials, moving large workpieces across the table, or using fixturing accessories, the plasma nitrided surface resists wear. This significantly extends the table’s service life, making it a solid investment for professional fabricators.

3. Comparison with Non-Nitrided Tables

To appreciate the advantage of plasma nitriding, it helps to compare Siegmund tables with standard non-nitrided welding tables.

• Hardness: Non-nitrided tables are generally much softer in comparison, making them more prone to dents and scratches over time. A typical non-nitrided table can’t match the 63-66 HRC hardness of a Siegmund table.

• Corrosion and Rust: Non-nitrided tables are also much more susceptible to rust and corrosion, especially in environments with high humidity. These tables require more frequent maintenance and are more likely to degrade over time.

• Maintenance and Cleaning: Because non-nitrided tables are more prone to spatter buildup, they require more aggressive cleaning methods, which can further degrade the surface. Plasma nitrided Siegmund tables, on the other hand, are easier to maintain thanks to their spatter resistance.

4. The Role of Plasma Nitriding in Precision Welding

Precision is critical in welding, and a flat, stable work surface is essential for achieving accurate results. The plasma nitriding process ensures that Siegmund tables retain their flatness and resist deformation, even under heavy loads and extreme temperatures. This allows fabricators to consistently produce precise, high-quality welds, even on complex projects.

The added hardness of the nitrided surface also means that clamping tools and fixturing accessories can be used repeatedly without wearing down the table, ensuring that each setup is as precise as the last.

5. A Long-Term Investment

Siegmund welding tables are not just tools; they are long-term investments. Thanks to the plasma nitriding process, these tables outlast and outperform traditional welding tables by a significant margin. The durability, corrosion resistance, and reduced maintenance requirements make them a smart choice for professionals who want to invest in reliable, long-lasting equipment.

Conclusion

Plasma nitriding is one of the key factors that set Siegmund welding tables apart in the industry. By enhancing the surface hardness, improving corrosion resistance, and minimizing welding spatter adhesion, plasma nitriding ensures that Siegmund tables perform reliably, even in the most demanding environments.
