Jet laser and its role in avoiding problems resulting from traditional laser cutting of metals and increasing the quality of cutting

Laser technology is one of the most important inventions of humanity and the fastest growing technology in the twenty-first century. Since its invention in 1960, it has developed rapidly and provided the world with new applications and fields that led to the establishment of advanced and modern industries. The laser is characterized by important characteristics such as strength, accuracy, speed, ease of control and guidance, and monochrome compared to other light sources, which made its application useful in many industrial processes that require a high degree of accuracy and quality such as welding, cutting, drilling, surface treatment, deposition, and others.

Despite these important advantages of laser, scientific studies have proven that the use of traditional (dry) lasers in cutting metals leads to some problems that appear on the surface of the pieces, such as oxidation and thermal damage resulting from the formation of heat-affected areas, in addition to the accumulation of slag and the generation of harmful fumes and smoke during cutting, which affects the quality and accuracy of the cut.

Therefore, the research is interested in studying the (wet) jet laser and its ability to avoid those problems that appear on the cutting surface as a result of the use of traditional lasers in cutting metals, and thus the quality, accuracy and efficiency of cutting can be increased.

The research attempts to answer a group of questions, the most important of which are: Does the use of a jet laser avoid the problems resulting from traditional lasers?
