PRINCIPLES OF HIGH FREQUENCY INDUCTION TUBE WELDING

Heat generated at the interface melts a thin layer of plastic in both components and thus forms a joint through molecular interdiffusion. To form a strong bond, it is important that the weld interface is exposed to sufficient heat to melt the polymer without degrading it. Delivery of the thermal energy by the laser beam is affected by process parameters, such as laser power, scan speed, beam

MATHEMATICAL MODELLING OF THERMAL AREA IN CUTTING

• Inspections and tests required during the welding operation are performed as specified. • Completed weld has been inspected to ensure that it will meet the visual requirements. Additional nondestructive examination is usually performed by other personnel. Types of Inspection Inspections are performed to determine whether a weld meets expectations. Depending on the final use of the

Strategy of Considering Microstructure Effect on Weld

Parameters that control the solidification of castings also control the solidification and microstructure of welds. However, various physical processes that occur due to the interaction of the heat source with the metal during welding add a new dimension to the understanding of the weld pool solidification.

Strategy of Considering Microstructure Effect on Weld

Moving heat sources is a topic in transient heat transfer that is applicable to engineering problems, particularly welding engineering. In the early 20th Century, welding engineers began studying moving heat sources, both empirically and theoretically. Depending on welding parameters, plate geometry and material properties, the solution takes

APPLICATION DATA SHEET Copper

Efficient energy coupling between beam and material is fundamental for any effective application of laser technology. Qualitative a quantitative experimental assessments on laser radiation absorption phenomena during both high power density (welding) and low power density operations (surface treatments) are providing useful information on

On the prediction of effect of direction of welding on

matical model of heat distribution during thermal laser treatment is simplified to a linear problem of heating a half-space, that can be used for plates of finite thickness. Despite a number of assumptions, this approach gives satisfactory qualitative and quantitative understanding of the heating stage. The accepted model allows us to control the quality criteria of the surface layer and
