There are multiple ways to cut steel and multiple technologies and processes to coincide with them. Determining the most appropriate method to a set type of steel can be difficult. Some methods are fast, some take time. Some are designed for thick steel; some can cut razor-thin steel with the perfect precision. The following guidelines will assist in determining the best method for the most accurate and desirable cut. http://www.shapecut.com.au/blog/how-to-select-the-best-method-for-cutting-steel/

1. HOW TO SELECT THE BEST
METHOD FOR CUTTING STEEL

2. There are multiple ways to cut steel and determining the most
appropriate method to a set type of steel can be difficult.
Some are designed for thick steel; some can cut razor-thin
steel with the perfect precision.

3. ANALYSE THE
THICKNESS OF THE STEEL
S T E P O N E
Laser cutting is perfect for steel that is thinner than 0.080”
Laser or plasma cutting is suitable for steel thinner than 0.125”
Laser, plasma or waterjet methods will suit steel thinner than 0.250”
Oxyfuel will cut anything over 8” with perfect precision
Oxyfuel or waterjet cutting is adequate for steel thicker than 2”

4. Plasma cutting is usually the most accurate method for
steel fabrication. If heat is not desired (used with oxyfuel,
plasma and laser) the waterjet method is an ideal option.

5. COST ANALYSIS
S T E P T H R E E
Waterjet steel cutting is often the most expensive form of steel
cutting and oxyfuel is usually the most cost-effective.
Using multiple plasma torches can cost more, whereas waterjet cutting
can run multiple nozzles from one intensifier pump, which means the
quote cost is finalised prior to starting the job.

6. MULTI PROCESS METHODS
O T H E R O P T I O N S
Some complex steel cuts require multi-process methods of cutting.
Plasma and waterjet cutting are often used together as are waterjet
steel cutting coinciding with oxyfuel cutting.
Multi-process cutting allows for accurate and slower precision for
intricate contours and can achieve a quick, cost effective,
and productive result.
