Laser beam welding is used for precise parts such as core internal parts in nuclear power plants that require high quality. To weld large-scale and thick-wall products, the high power laser beam must be transferred and a deep penetration welding proc

The stress that exists in a body under no external force is called the inherent stress. The strain that is the cause (source) of this stress is called the inherent strain. This study proposes a general theory of an inherent-strain-based measurement m

We initially applied the 6kW to 10kW YAG lasers in order to weld and cut heavy components. We used optical fiber beam guide systems whose core diameters are 0.6mm to 0.8mm in length and having a standard length of 200m. Using the above systems we can
