These dates mark the superstar’s last-ever tour, the end the road for one of pop culture’s most enduring performers. Elton’s new stage production will take his fans on a musical and highly-visual journey spanning a 50-year career of hits like no one has ever seen before. “Performing live fuels me and I’m ecstatic and humbled to continue to play to audiences across the globe,” said Elton. “I plan to bring the passion and creativity thatduring long-term storage because of climbing movement of electrolyte (which is called as creeping).
On the other hand, in the sealing method by laser welding, since a sealing part and a cell can are joined to each other by welding, leakage due to the electrolyte creeping will not occur in principle after sealing. Sealing by laser welding is more appropriate in the light of reliability, including corrosion resistance. In the sealing method by laser welding, the electrolyte creeping will however occur at the time of welding by laser beam. Specifically, in a laser welding process, a sealing part is inserted into a cell-can opening before laser beam irradiates the sealing part, and the insertion causes the electrolyte creeping because the edge of the sealing part comes into close contact
