When it comes to speed, precision, and clean results, few tools compare to a plasma cutter. Whether you’re building structural steel frames or crafting custom architectural features, plasma cutting gives you the accuracy modern steelwork demands.
At Riteweld Engineering, we use advanced plasma cutting equipment at our facility in Banbury. We support homeowners and contractors in Oxfordshire, Northamptonshire, Warwickshire, and across the UK. Let’s explore how plasma cutting works, what makes it so effective, and why so many builders and developers choose Riteweld.
What Is a Plasma Cutter?
A plasma cutter uses a high-temperature jet of plasma to slice through electrically conductive metals like mild steel, stainless steel, and aluminium. Plasma is the fourth state of matter—created by applying an electrical arc to compressed gas, usually air.
The machine creates a superheated, focused beam of plasma (over 20,000°C) that cuts metal with extreme precision and minimal waste.
How Plasma Cutting Works — Step-by-Step
-
Gas Supply Initiated
Compressed air, oxygen, or nitrogen flows through the cutter’s nozzle. -
Electrical Arc Engaged
The arc passes through the gas, energising it and turning it into plasma. -
Heat Transfer Begins
The plasma stream touches the metal and melts the targeted area. -
Clean Cutting Execution
The high-pressure gas pushes the molten metal away, producing a neat, narrow cut (called a kerf).
Most professional projects use CNC plasma machines, allowing for consistent, accurate cuts—even for intricate or repeated patterns.
Why Plasma Cutting Is Essential in Steel Fabrication
Plasma cutting is a vital part of what we do at Riteweld. Here’s why:
-
Speed: Much faster than manual cutting or oxy-fuel methods.
-
Accuracy: CNC control delivers precise, repeatable cuts.
-
Versatility: Works on both thin sheets and thick beams.
-
Clean Finish: Minimal cleanup required due to reduced slag.
-
Cost-Effective: Saves labour time, especially in high-volume runs.
Real-World Applications from Riteweld
We support clients at all stages—from homeowners to large-scale developers. Here’s how plasma cutting fits into the bigger picture:
1. Custom Structural Steel
We cut heavy-duty items like I-beams, baseplates, and brackets to exact measurements—ready for structural use.
2. Architectural Detailing
Need decorative balustrades or curved stair stringers? Plasma lets us create intricate forms that stay strong and look fantastic.
3. Consistency for Developers
We often produce hundreds of identical components—perfect for housing developments or commercial projects.
4. Fast, Local Turnaround
Because we operate from Banbury, we can fabricate and ship across Oxfordshire, Northamptonshire, Warwickshire, and beyond—quickly.
