Consider, for example, an ordinary small pulsed laser which emits 10 joules of energy in a pulse with a duration of 1 millisecond. With simple optics, it is possible for users to collect and focus the beam to an area less than 0.01 cm in diameter. Consequently, this leads to an irradiance greater than 10^8 watts/cm² at the target surface—an extremely high value. Indeed, this is much higher than what any conventional light source can deliver. Furthermore, it is also considerably higher than what almost all other welding sources deliver. For instance, an oxyacetylene torch delivers about 10^4 watts/cm². Only an electron beam machine, which is very large and requires a vacuum system, can compare to lasers in their ability to deliver such high values of power per unit area. Lasers for Welding However, only a few of the many types of lasers that developers developed are useful for welding applications. The main requirement is that the laser must be able to produce sufficiently high levels of radiant power to melt the material to be welded. Operators, therefore, must carefully choose the laser’s properties to fit a specific welding application. These include: The workpiece should absorb the wavelength of the laser light well. The laser must provide enough power to produce melting. The pulse duration for pulsed lasers must be long enough to permit heat penetration into the material. The pulse repetition rate for pulsed lasers must be high enough to weld a seam if seam welding is required. Table 1 lists some of the available lasers that manufacturers used for welding. The table also gives some of the typical values of important parameters that influence the welding. It’s important to note that the values in the table indicate commercially available options, not necessarily the highest values anyone has ever attained.
