Product // Applications // Laser cutting // Comparison
Method Advantages Disadvantages
Water jet • Can cut almost all materials even if the material is very thick • Loud, wet cutting technique
• Material remains shape/form regardless of temperature increase • Cuts hard materials relatively slowly

• Narrow kerf possible • Comparatively high investment and operating costs (e.g. in comparison to plasma arc cutting up to 20 times less effective depending on the material to be cut and the material thickness)
• Very good cutting quality
• Technique can be largely automated
Laser • High level of contour accuracy when cutting sheet metals of low or medium thickness • Can only cut sheet metals made of construction steel, alloyed steel and aluminium if they are not too thick
• Can cut thin sheet metals rapidly • Cutting reflective material surfaces can be difficult
• Can cut complicated shapes such as small holes and acute angles • In order to cut cleanly, the guidance of the laser head over the workpiece surface needs to be extremely accurate
• Right-angled cutting edges • Low degree of efficiency (CO2 laser max. 10%)

• High level of automation possible

• Relatively high investment and operating costs (high level of gas consumption)

• Very low kerf width (0.2 – 0.4 mm)
Plasma arc • Can cut all (electrical) conductive materials • Can only cut materials with a thickness of up to 160 mm when dry cutting
• The best solution for cutting high-alloyed steels and aluminum materials of medium and above average thickness

• Slightly wider kerf
• Very suitable for cutting construction steels of up to 30 mm in thickness
• Can cut high-strength construction steels without a significant temperature increase
Schnelles Schneiden auch von harten Werkstoffen möglich

• Can cut hard materials rapidly
