Compared to plasma cutting: Flame cutting operates at lower temperatures, resulting in slower cutting speeds compared to plasma cutting; additionally, it cannot cut stainless steel or many non-ferrous metals. Its advantages include the ability to cut very thick plates (my country has mastered flame cutting technology for thicknesses up to 2000 mm), relatively low equipment and operating costs, and less pollution compared to plasma cutting machines.
Compared to laser cutting: Flame cutting machines lag significantly behind laser cutting machines in terms of cutting speed, precision, and the variety of materials that can be cut; however, they outperform laser cutting machines regarding cutting thickness and cost-effectiveness.
Compared to high-pressure waterjet cutting machines: High-pressure waterjet cutting machines offer superior precision and material versatility compared to flame cutting machines; however, flame cutting machines excel in cutting speed and thickness capabilities, while also featuring relatively lower equipment and operating costs.
Overall conclusion: Flame cutting machines require low initial investment and handle great thicknesses, making them suitable for rough processing industries where high precision is not required.
