mainly, gas laser (co2), solid state laser (nd:yag and ruby lasers) and fiber laser are primary types of lasers used in welding. characteristics of laser beam welding include the following: the power density of laser beam is high, and it is of the order 1 mw/cm2. due to high power density it has small heat-affected zones. so, the rate of heating and cooling is high. for welding purpose pulsed or continuous laser beams are used. laser welding is a versatile process since it is capable of welding different types of material like carbon steels, stainless steel, hsla steels, aluminum and titanium. it produces high quality weld. laser welding can easily accessible since the beams can be focused, aligned and directed by optical elements. laser beam can be focused on a small area, permitting the joining of small, closely spaced components with tiny welds. due to high laser penetration power it’s aspect ratios (i.e., depth-to-width ratios) is high i.e. 10:1.
the application range of lbw covers the finest welding of non-porous joints in medical technology to precision spot welding in electronics or the jewellery industry, to deposit welding in tool and mould-making and welding complete car bodies in auto mobile construction. laser brazing: brazing is a joining process that uses a filler metal or alloy to melt at temperatures above 450°c. laser soldering: during the soldering process, the filler metal or alloy is heated up-to melting temperatures less than 450°c. so, generally laser output power less than 100 watt is required for melting the filler material laser plastic welding: diode lasers are the ideal choice for plastic welding. with different wavelengths ranging from 808 to 1470 nm spot and seam welding: seam welding are a variation of spot welding. in laser seam welding, the part to be welded is moved or rotated under the focus head allowing laser spot welds to overlap.
hypodermic needle features: component:medical equipment material: stainless steel process: laser micro drilling source of laser: fiber laser industry: medical
micro-drilling by laser relies on controlled removal of material exposed to high-intensity laser irradiation. usually, this term is applied to holes or openings with diameters between 1 µm to 1 mm. the exact mechanisms of material removal during micro-drilling are defined by the material properties, characteristics of the laser, and the configuration of the machining process.

laser ablation is the process of removing a layer of material precisely. in ablation, laser removes layers by evaporation or sublimation. laser ablation leaves the color of beneath laser. the general difference between laser ablation and laser cleaning is that ablation seeks to remove material, whereas cleaning aims to clean the material.

features: component:filigree material: gold, brass, bronze and all composite metals. process: laser cutting source of laser: fiber laser industry: all industries
laser cutting is carried out by applying enough power at a low speed to completely vaporize material all the way through. filigree cutting by laser is one of the important applications in jewelry industrial. for this application we have extra fine & high frequency lasers having number of waveforms to select for different materials.
less haz produced during cutting oxidation process can result in a variety of colors a slower, more drawn-out process common in the medical industry applications such as internal tracking and branding.
2d engraving on 2d surface features: component:coin die material: gold, brass, bronze and all composite metals. process: laser deep engraving source of laser: fiber laser industry: die & mold(all industries)
laser engraving is the process of removing a portion of material to leave an engraved mark which is visible beneath. the laser creates high heat during the engraving process, which essentially causes the material to vaporize during each pulse. several passes of laser may be required to get the desired depth of engraving. laser etching is a subset of laser engraving. during the process of laser etching, the cover layer of any material is vaporized, producing little to no depth but usually high contrast marking.
