Hot-wire laser cladding is a coating method with excellent properties and high deposition rate. Process is rather simple and fundamental relationships of basic parameters like laser power, amperage, voltage, travel speed and spot sizehave been studied experimentally. Solid wires are easily melted by the melt pool generated...$28.00

Presented at ICALEO 2007
As higher power disc and fiber lasers become available, questions arise concerning the stability and durability of focusing optics. Even at familiar YAG power and brightness (i.e. 4 kW from 600 um fiber) focusing optics are known to exhibit shifts in position and changes in focal spot size. At higher power levels these focusing issues will become significantly more troublesome. Traditional 1.06/1.07 um focusing optics are construc...$28.00

Presented at ICALEO 2007
In order to restrain heat input and increase productivity in thin steel sheet welding compared to arc and laser welding processes, a laser GMA hybrid welding process with single-mode fibre laser was developed. The effects of some basic parameters such as laser power, focal position and laser arc distance were investigated and discussed in view of weld quality and process efficiency. Moreover, the influence of gap on weld quality, hardness and static strength was considered. Ba...$28.00

Titanium alloys offer higher strength to weight ratios than steels, better fatigue performance than aluminium alloys and better corrosion resistance than aluminium alloys and stainless steels and are now increasingly used in applications in the aerospace, chemical plant, power generation, oil and gas, medical and sporting goods sectors. For aerospace applica...$28.00

Presented at ICALEO 2007
Today laser alloying of Aluminum is a well known technique in order to increase the wear resistance of parts. The process is typically limited in depth to about 1 mm. In this study it is shown that a deeper alloying is possible by using the deep penetration effect caused by a highly intensive laser beam. The laser beam is scanned in a circular motion in order to control the track profile. By this manner o...$28.00

Presented at ICALEO 2007
Laser hybrid welding processes are gaining more interest in many sectors of metal industry. The process is already in successful use for example in automotive, ship building and construction industry. The laser hybrid welding processes are traditionally a combination of CO2 or Nd:YAG laser together with MIG/MAG or TIG welding. The arc welding source is chosen depending on whether there is also need for extra material. The maximum powers available for thes...$28.00

Laser welding has become one of the most expanding areas for industrial laser applications. The increasing cost effectiveness of the laser process is accompanied by the development of new high efficient laser sources, such as the new disk laser. TRUMPF introduced the disk laser several years ago, and today it has become the most reliable laser tool on...$28.00

Presented at ICALEO 2007
Thin disk lasers as well as fiber lasers are distinguished by their strong focusability and high efficiency. The stronger focusability can be used for an expansion of the application range. Weld seams of unprecedented high aspect ratios independent of the laser type can be achieved which are only known from the electron beam welding until now. Based on results of thin disk and fiber laser experiments it has been shown in earlier publications that the influence of the div...$28.00
