Cutting

Thermal cutting requires a process-specific cut plan that addresses the heat-affected zone and delayed cracking risk.

Decision inputs

Pre-commercial, indicative guidance. The final procedure and safety controls require competent review, order data and the actual material document.

  • 01

    Plate identity and actual chemistry.

  • 02

    Thickness and starting material temperature.

  • 03

    Cutting method, geometry and pierce location.

  • 04

    Cold, thick or high-restraint details.

  • 05

    Planned edge finishing and post-cut inspection.

02 / Decision tree

Decision sequence

  1. 01

    Assess material condition

    Verify temperature, surface, identity and documents.

  2. 02

    Plan pierce and edge geometry

    Place pierces and edges so local heat and restraint can be controlled.

  3. 03

    Use controlled cooling

    Avoid uncontrolled rapid cooling and mechanical loading during cooling.

  4. 04

    Complete post-cut inspection

    Inspect the edge and heat-affected zone after the relevant delayed cracking interval.

03 / Inspection

Post-process inspection

  • 01

    Visually inspect the cut edge, pierce and heat-affected zone.

  • 02

    Set any additional examination from geometry, risk and ordered requirements.

04 / Hold point

Stop and escalation conditions

  • HOLDCold or thick high-restraint geometry has no assessed cut plan.
  • HOLDThe plate is damaged or unidentified.
  • HOLDSupport or restraint differs from the plan.
  • HOLDThe edge shows cracking indications.
