3.1 Combustion cutting
JB/T10045.1—1999
Combustion cutting is a thermal cutting method in which the material is heated to a combustion state at the incision and the oxides produced at the incision are blown out by a cutting oxygen flow to form the incision.
3.2 Melting cutting
Melt cutting is a thermal cutting method in which the material is heated and melted at the incision and the molten product is blown out by a high-speed and high-temperature gas jet to form the incision.
3.3 Sublimation cutting
Sublimation cutting is a thermal cutting method that heats and vaporizes the cut of the material, so that the vaporized product expands or is blown out by a gas jet to form a cut.
Classification by processing method
4.1 Manual cutting

5.1 Thermal cutting using gas flame
The heat required for gas flame thermal cutting is generated by oxidative combustion, and the oxide or melt is driven out by the cutting oxygen flow. 5.1.1 Gas cutting (Fig. 2)
The heat energy of the gas flame is used to preheat the workpiece cut to the combustion temperature, and then a high-speed cutting oxygen flow is ejected to make it burn and release heat to implement cutting.

Preheating oxygen
A method of adding pure iron powder or other flux to the cutting oxygen flow and using their combustion and slag-forming effects to achieve gas cutting. 5.1.2.1 Metal powder-flame cutting (Fig. 3) Metal powder-flame cutting is a gas flame cutting method in which metal powder is fed to the reaction site. Additional heat is generated by the combustion of the metal powder, and the cutting slag is diluted by the generated oxides, so that the slag can be driven away by the cutting oxygen flow. The reaction process proceeds in the direction of movement and forms a cut.
5.1.2.2 Metal powder-melting cutting (Fig. 4) JB/T10045.1—1999
Metal powder-melting cutting is a thermal cutting method using gas flame and cutting oxygen when metal powder is fed. The material is melted by the heat of gas flame and burning metal powder, and the metal (or ore) melt is transformed into a thin slag (or lava), which is driven away by the cutting oxygen flow. The reaction process proceeds along the moving direction to form an incision. Cutting torch

Figure 6 Flame gouging
Flame perforation is a hot perforation method that uses an oxygen spear to perforate an ore or metal material. The exposed end of the oxygen spear is heated to the melting point and burns under the condition of adding oxygen.
In the ore material, the metal oxides produced when the oxygen spear burns turn the viscous ore melt into a thin slag (lava), which is then discharged by an oxygen flow.
In metal materials, metal is oxidized and burned in an oxygen flow and discharged by the oxygen flow, thus forming a hole; many holes are connected to form a row of holes or a cut.
5.1.6 Fire melting cleaning (Figure 9)
Flame cleaning is a thermal cutting method that uses a gas flame to remove the cover layer or coating on the surface. The surface of the metal or ore workpiece is rapidly heated, causing the organic or inorganic cover layer or coating to peel off or transform and be removed. 618

Arc-oxygen cutting is a thermal cutting method that uses arc plus cutting oxygen for cutting. The arc burns between the hollow electrode and the workpiece. The heat generated by the arc and the material burning enables the material to burn continuously through the cutting oxygen. The molten material is discharged by the cutting oxygen. The reaction process proceeds along the moving direction to form an incision.

Arc-compressed air gouging is a thermal cutting method that uses an arc and compressed air to cut on the surface. The heat generated by the arc and the burning of the material enables the material to melt and burn continuously. The reaction process develops in the direction of movement, and the compressed air flow drives away the molten material and slag to form an incision.
5.2.3 Plasma arc cutting
A method of cutting using the heat energy of a plasma arc. 5.2.3.1 Plasma arc cutting with transferred arc (Fig. 12) When the transferred arc is used for plasma arc cutting, the workpiece is in the cutting current loop, so the material to be cut must be conductive. 5.2.3.2 Plasma arc cutting with non-transferred current (Fig. 13) When plasma arc cutting with non-transferred arc is performed, the workpiece does not need to be in the cutting current loop, so both conductive and non-conductive materials can be cut.
5.3 Thermal cutting using beam
5.3.1 Laser cutting
Method of cutting using the heat energy of a laser beam. 5.3.1.1 Laser-combustion cutting (Fig. 14) Laser-combustion cutting is a method of cutting by heating a material suitable for flame cutting to a combustion state using a laser beam. 619
