Here will introduce more details of battery of laser pointer

The capacity of laser pointer is large.
Melting metal parts with metallurgical bonding entity, the relative density of almost 100%, greatly improved the performance of metal parts; (3) Because of the small diameter of the laser spot, and thus lower power to melt the high melting point metal , making the manufacture of parts with single-component metal powder possible. Its essence is a computer under the control of three-dimensional laser cladding. Due to rapid solidification characteristics of laser cladding, metal parts to create a uniform fine dendritic structure and excellent quality, density and performance with conventional metal parts. Laser multilayer cladding to develop a variety of ways. The battery of laser pointer can be used for a longer time.
The most representative is the U.S. Sandia National Laboratories (Sandia National Laboratories) developed called laser engineered net shaping technology (Laser Engineered Net Shaping, referred to as LENS) metal rapid prototyping technology. The method has been successfully produced stainless steel, maraging steel, nickel base superalloys, tool steels, titanium alloys, magnetic materials and nickel-aluminum intermetallic compounds workpiece, part density close to 100%. Figure 3 shows the U.S. Sandia National Laboratories, the LENS technology manufacturing metal mold. Figure 3 U.S. Sandia National Laboratories using laser engineered net shaping process (LENS) manufacturing metal molds selective laser melting (SLM) and laser engineered net shaping (LENS) technology due to the shape of pieces of dense. The smaller the capacity of laser pointer is, the shorter time the battery of the laser pointer can be used for. This method is suitable for smaller precision molds. Here will introduce more details of battery of laser pointer .
Rofin-Sinar manufactured StarWeld welding machine is more representative of such equipment, shown in Figure 4. Figure 4 Rofin-Sinar, the StarWeld laser welding machine mold laser cleaning application of high-energy laser pulse to remove the mold surface in the course of dirt is another use of laser technology in the mold industry. Cleaning mechanism are two: First, the direct use of the laser heating dirt, so that the gasification of volatile or instantaneous thermal expansion and steam away from the mold surface of the substrate; There is a high energy density, high frequency pulse laser dirt layer split the stress out of the mold matrix. More details of the battery of laser pointer will be described.
Compared with the traditional sandblast cleaning methods, laser cleaning with cleaning speed, no damage to the mold surface, line cleaning (which can save a lot of demolition, installation, debugging time) the advantages. At present, Germany JET laser system produced laser cleaning equipment is relatively advanced.
