|The most challenging part was the manual work required to ensure that the shape of each individual part changed accurately when assembled. When machining the spherical surface, we could not read the subtle contractions and expansions of the sheet, so another question was how far to reduce the clearance between welded parts. For this we used sheet scissors to cut and make adjustments.
The fact that the overall finishing of the weld was even despite the complexity of the shape seems to have been well-received. We are tremendously pleased to be awarded such an honor as the Gold Award. It will be an encouragement to us in future.
We are never 100% satisfied with our finished shape and welding, including that of our submission this year. We are always looking for ways to make our work faster, easier and cleaner. The work we do on a daily basis is equal to the work we submitted to the Technology Fair. We consider skill improvement to be an absolute condition for performing our work. We will continue to take every opportunity to seek objective opinions.
