Holes filled beam irradiation

Holes filled beam irradiation in the wall material continuous high temperature steam generated by evaporation, the walls of the hole surrounded by molten metal, liquid metal that is around four weeks of solid materials. Outside the hole wall surface tension of liquid flow and the parietal cavity continuous with the pore pressure generated by the steam rally and maintain homeostasis. Beam continuously into the holes, holes in a continuous flow of foreign material, with the beam moves, the hole is always in steady-state flow. That is, holes, and the molten metal around the hole wall of the forward speed of the beam with a leading forward, remove the molten metal fills the hole left by the gap and subsequently condensed, so the formation of the weld.  laser pointer has different output types. This kind of laser pointer has the higher expense. Deep penetration of the laser impact factors include: laser power, laser beam diameter, material absorption rate, welding speed, shielding gas, lens focal length, focus position, laser beam position, weld start and end point of the laser power gradually rise , gradually decreased control. Deep penetration of laser characteristics and advantages. Characteristics: high aspect ratio. Because the molten metal around the cylindrical steam chamber and extends to the formation of the workpiece, the weld becomes deep and narrow. Minimum heat input. Because the source chamber temperature is high, the melting process occurs very fast, very low heat input workpiece, heat distortion and heat affected zone is very small. High compactness. Because it is full of high-temperature steam in the weld pool small Kongyou Li mixing and gas escape, leading to generate non-porous weld penetration. High cooling rate after welding to weld and easy miniaturization. Strong weld. Precise control. Non-contact, air welding process. The technical reform of laser pointer should be considered at first.
Advantages: As the focused laser beam is much higher than the conventional method of power density, resulting in welding speed, heat-affected zone and deformation are small, you can weld titanium, quartz and other hard to weld materials. Because the beam is easy to transport and control, and does not require frequent replacement torch, nozzle, significantly reducing downtime auxiliary time, so there are load factor and efficiency are high. As the role of purification and high cooling rate, weld strength, high overall performance.
