Fillet welds are inherent part of large structures in shipbuilding industry, where distortion is a major issue. Hybrid laser welding enables fully penetrated fillet welds to be achieved with a lower energy than arc-based welding processes. This has significant effect on increase of productivity, decrease of distortion and reduction of weight. To achieve defects-free welds with good fa...$28.00

The use of cladded pipe-lines with an inner layer of stainless steel or Nickel base alloys tends to increase for deep offshore pipe line applications. End users and certification code generally ask for conventional welding. This ensures an optimum quality on the inner side of the root pass and preserves the anti-corrosion property of the inner clad. However, this is obtained with a small thickness of the first pass and a low welding speed. Laser hybrid welding seems to be an attractive technique for increasing both the thickness of the root pass and the welding speed. Combinati...$28.00

The use of laser welding is enlarging to new applications partly via various technological advancements. These include development of lasers and laser system components together with development in process techniques. The first studied and reported of so called laser-hybrid welding processes was laser-TIG-hybrid welding. This process has advantages over the laser-MIG-hybrid process due to the fact that wire feeding and arc parameters can really be controlled separate...$28.00

Presented at ICALEO 2013
Monitoring both near and far field laser beam parameters is extremely helpful in understanding the quality of a laser process. The measurement of such parameters has not been practical to date due to the required disruption of the process beam in order to make the measurement. A significant quality control enhancement could be realized if one could monitor both near and far field patterns of the laser system during the process if it could...$28.00

Presented at ICALEO 2013
The paper reports the research of laser drilling technology by ns pulse laser for purpose of making cooling holes with thinner recast layer or even without recast in aero-engine. In research we employ diverse modes in making holes in nickel-based alloy samples. The first way is making holes with low power high frequency ns pulse laser in scanning mode of removing the material layer by layer, the second one is making holes with ns width pulse train laser in percussion mode, the third is ...$28.00

Rotation sintering, also known as slush molding, is used to manufacture molded skins, such as cockpit or door interior panels for cars. At present, approx. 80 percent of molded skins are manufactured using electroforms due to the complex free-form surfaces, and surface structures such as leather graining. The manufacture of these electroforms is time-consuming and expensive. The aim is to replace conventional electrofor...$28.00

In order to guide cooling air through turbine blades, bore holes with 500-800 microns diameter need to be drilled into the blades. The tolerance of the bore hole diameter must not exceed a range of about 10-30 microns so that a constant air flow capacity can be guaranteed. For the determination of the bore hole diamet...$28.00

Laser welding of polymeric products has been manufactured for more than 20 years. During that time polymer welding has developed a lot. In spite of that, there are still some limitations in applying the process to the industry. Typically welding has been made in lap joint configuration with black and clear parts because of optical ...$28.00
