Laser cutting is a thermal cutting process that uses a high-energy-density laser beam to precisely process materials. Its basic principle is to the laser beam into an extremely small spot through an optical system, causing the material to be irradiated to reach the melting or vaporizing temperature in an extremely short time. the same time, with the help of auxiliary gases (such as oxygen, nitrogen, etc.), the molten or residual matter is blown away, thus achieving the separation of material. This process has the characteristics of high precision, high efficiency, and high flexibility, and is suitable for the processing of a variety of material types such as metal, non-, and composite materials.

The core elements of laser cutting include laser power, cutting speed, focal position, and the type and pressure of auxiliary gas. The coordinated regulation of parameters directly affects the cutting quality, such as the width of the cut, the roughness of the cross section, and the size of the heat-affected zone. Depending on the properties and thickness differences, the process needs to be adapted to different laser modes (continuous wave or pulse wave) and gas combinations to optimize the cutting effect.
 

Bending is a cold working process that applies external force to stainless steel sheets, causing plastic deformation and thus obtaining specific angles and shapes. The principle involves using the punch and die of a bending machine to apply pressure to the sheet, causing the material to undergo permanent deformation beyond its elastic limit while maintaining the integrity of its internal.

The key control parameters of this process include the bending angle, bending radius, bending force, sheet thickness, and die selection. Due to the high strength, hardness, toughness of stainless steel, special attention must be paid to the phenomenon of springback – the tendency of the material to partially return to its original shape after unloading. To for springback, the actual bending angle usually needs to be overshot by a certain value compared to the design angle.

Modern bending processes often employ CNC (Comput Numerical Control) bending technology, which precisely controls the sequence, depth, and pressure of bending through pre-programming, ensuring consistency and high precision in mass production. Bending steel is widely used in architectural decoration, sanitary ware, medical devices, and industrial parts manufacturing, serving as an important forming method to achieve both structural functionality and aesthetic design.

Laser welding is a high-precision fusion welding process that uses a high-energy-density laser beam as the heat source to achieve melting and connection of materials. Its basic principle is to focus the laser beam into a micron-level light spot through an optical focusing system, which instantly melts the local area the irradiated workpiece to form a molten pool. With the relative motion of the laser beam and the workpiece, the molten pool solidifies to form a continuousd seam.

This process mainly includes two modes: thermal conduction welding and deep penetration welding (keyhole welding): thermal conduction welding is suitable for precise welding of thin plates, shallow penetration and smooth surface; deep penetration welding, on the other hand, forms a plasma through high-power density vaporization of metal, which produces a perforating small hole, and can achieve single-pass full penetration of thick plates.

The core process parameters of laser welding include laser power, welding speed, defocus amount, type and flow protective gas. When welding materials such as stainless steel, aluminum alloy, and superalloy, it is necessary to adjust the parameter combination according to the material characteristics to control thed formation and suppress defects such as porosity and cracks.
