“…The torch angle was changed for the fourth cut to 45°, the preheating period was 60 seconds, and the cutting speed was 140 mm/min. The block's edge wall was melted by the cutting heat because the torch was too close to the edge (distance =15mm) [14,15].…”

In general, three different types of processes can be utilized to cut thick stainless-clad steel: waterjet cutting, mechanical cutting, and thermal cutting (plasma, flame, and EDM cutting). Because stainless steel contains a lot of Cr, Ni, and other elements with high ignition and melting temperatures, flame cutting is not recommended for direct cutting of stainless steel. Three different stainless-clad steel specimen thicknesses were prepared for this study, and cutting experiments were conducted utilizing the flame-cutting procedure. The tests demonstrate that using suitable flame-cutting parameters can yield the optimal cutting process parameters and successfully cut thick stainless-clad steel.

“…Then oxygen from the torch blows the melted steel away. Many studies have concluded that the heat source is uniformly distributed within a volume that resembles a cylinder with a truncated cone at both ends [8]. To indicate the direction of cutting heat source movement, the model can be split into two parts like the Goldak heat source model, as shown in Figure 1.…”

The welding and flame‐cutting process in the steel construction are commonly used, especially for the bridge structure. Some experiments about welding and cutting have been done separately by some researchers. The results from the experiments were also compared with the results from the numerical simulation under 3D or 2D models. The agreements between those results are as good as they predicted. Therefore, the numerical simulation is a better way to analyze the quality of the steel construction after welding and cutting without time‐consuming and a large amount of cost. But there are only a few research about the numerical simulation and the some of them are aimed to verify the experiments. In this study, the calculation about the residual stresses after welding and thermo‐cutting are considered from 3D‐model into 2D‐Model. The heat source model is simply regarded as curves of time and welding energy with the algorithm methods. And no matter the change of the parameters of the model and the heat source, the heat transfer and the residual stresses can be calculated with the 2D models as fast as possible. By the means of the finite element software Abaqus, the I‐profiles are easy to receive the job results with the input parameters. The influence of the welding and cutting process are visual and direct.

“…Despite the widespread use of the given technologies in practice, real results on the thermal cycling during thermal cutting are rather sporadic [5][6][7]. When numerical simulations are used to optimize the process, the temperature cycle is the basic dependence to set up and verify the process [8][9][10]. This paper focuses on the two most widely used thermal cutting technologies, namely oxyacetylene flame cutting and air plasma cutting.…”

Material parts can be separated either mechanically or thermally. During the thermal cutting of the material, the base material is locally melted, burned, or vaporized. The different methods are distinguished by the heat sources that supply them with the necessary energy. The application of the different thermal cutting methods varies depending on the type of material to be cut, its thickness, the resulting desired cut quality, and the overall economic efficiency. This paper deals with the study of temperature cycles formed during thermal cutting of carbon steel of S355 type by oxy-acetylene flame thermal cutting and air plasma cutting. The obtained experimental data are used in the numerical simulation of the thermal cutting process by the given technologies.
