2.1 Background to the proceedings

When cutting thick carbon steel plates, particularly those over 40 mm, traditional flame cutting requires lengthy preheating times to initiate the piercing process. This reduces productivity, increases the workpiece’s thermal exposure and can cause significant deformation of the material.
COLT technology combines the speed of laser-assisted piercing with the efficiency of flame cutting.
The laser enables rapid penetration of the material and stabilises the start of the cut; the flame process then completes the cut with reduced dwell time and greater consistency in medium and thick plates.

2.2 Scope of application

The solution is recommended for carbon steel and low-alloy steels that are prone to oxidation, with thicknesses ranging from 10 to 200 mm. Its optimal performance range is between 30 and 120 mm, where the laser-flame combination offers a particularly significant productivity advantage.

• Applications: heavy machinery, steel structures, shipyards, engineering workshops, mining, metal fabrication and industrial cutting of thick plates.

•    Operational objective: to improve piercing times, reduce reliance on manual adjustments and increase process repeatability.

•    Expected outcome: higher productivity per plate, better cross-section quality and lower energy costs compared to high-power laser alternatives.
