laser welding ppt*******This presentation discusses laser beam welding (LBW), including what a laser beam is, its properties, types of lasers, the LBW process, principles of operation, . This document discusses laser beam welding, including what a laser beam is, the different types of lasers, and the laser beam welding process. It describes how laser beam welding works by focusing .
This document discusses laser beam welding and provides information on key concepts. It begins by defining what a laser is and describing spontaneous and .
When focused on a surface, laser light creates the heat used for welding, cutting and drilling. The workpiece and the laser beam are manipulated by means of robotics. The . Laser Welding Machine industry by Technology (Fiber Laser Welding Machine, Cou2082 Laser Welding Machine and Solid-State Laser Welding Machine), By Application (Medical, Electronics, .
Laser Beam Welding The laser beam is focused onto the workpiece by a set of mirrors. When the laser beam is moved relative to the workpiece, the energy of the focused laser beam melts the metal so that a joint is formed.
The document discusses different types of lasers, including solid-state Nd:YAG lasers, gaseous CO2 lasers, direct-diode lasers, and fiber lasers. It notes the advantages and limitations of laser beam welding and .Laser Welding Overview. Description: As the laser applies the melting energy tightly localized, very compact structures with welding seams extremely close to heat-sensitive components can be realized. – .It discusses the advantages of laser beam welding over traditional welding in allowing for higher precision, lower heat input and distortion, and easier automation. The document also outlines various laser beam .Like electron-beam welding (EBW), laser beam welding has high power density (on the order of 1 MW/cm 2) resulting in small heat-affected zones and high heating and cooling rates. The spot size of the laser can vary between 0.2 mm and 13 mm, though only smaller sizes are used for welding. The depth of penetration is proportional to the amount of . Kinds of Materials That Can be Laser Welded. The most common materials that can be laser welded are listed below: Metals: Examples are: aluminum, copper, brass, steel, titanium, and nickel. The .Laser Beam MEACHINING Ppt Final 2 - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Laser beam machining is a non-traditional . 5. LASER BEAM WELDING • A fusion joining process that joins materials with the heat obtained from a concentrated beam of coherent, monochromatic light impinging on the joint to be welded • The laser beam is and focused as a tiny spot on the material via a combination of mirrors and lenses • LBW is a non-contact process, and .
This meant that laser welding was unstable and unrealistic for production. The fiber laser’s high brightness overcomes this limitation, because the high power density enables consistent absorption of the laser power. In addition, the relatively high welding speed that can be used avoids overheating the weld and soWhen laser welding plastics using the transmission welding method, two types of thermoplastics are joined with one another: the laser passes through the transparent mating part and the absorbing mating part is heated. The absorbing plastic melts the transparent joining area. The mating parts must be pressed together using a suitable fixture in .The fibre laser welding of two different dual phase steels HCT980X and HCT600X was evaluated. The sheets with thickness of 1.2 mm were welded using the solid-state fibre laser IPG type YLR 4500 with maximum output 4.5 kW and wave length 1060 nm at graduated beam powers and welding speeds. 7. CLASSIFICATION OF WELDING PROCESSES • There are about 35 different welding and brazing processes and several soldering methods in use by industry today. • There are various ways of classifying the welding and allied processes. For example, they may be classified on the basis of: – Source of heat, i.e., flame, arc, etc – .The laser welding machine has the advantages are simple operation, welding seam smooth and cleam, fast welding speed, and no consumables. Welding in thin stainless steel plate, iron plate, aluminum plate and other metal materials can perfectly replace the traditional argon arc welding and electric welding technology. . ©2018 PPT - A . 2. Introduction i. Electron Beam Welding is a fusion welding process in which a beam of high-velocity electrons is applied to the material to be joined. ii. The work-piece melt as the kinetic energy of the electrons is transformed into heat upon impact. iii. The EBW process is well-positioned to provide industries with highest quality welds and .

8. When overlaying with a laser an optical arrangement is used to focus the laser beam on the work piece and heat it. Simultaneously hardfacing material in the form of powder is introduced into the laser beam and melted. Due to the narrow heat affected zone and the fast cooling rate the heat input is low, thereby producing an almost stress free .
