Process Advantages Disadvantages

This document compares different cutting processes: - Oxy-fuel cutting has low capital and consumable costs but is limited to mild steels and produces a wide heat-affected zone. - Plasma cutting can cut a wide range of materials, produces a narrow heat-affected zone and cut edge, but has higher capital and consumable costs. - Laser cutting produces an extremely narrow cut width and minimal distortion but has high capital costs and the beam must be screened. - Abrasive water jet cutting has no heat effect but has high capital costs and the abrasive cannot be recycled.
