Stainless Steel Welding And Polish On Chicago Cloud Gate

How is Chicago Cloud Gate welded? Why is it so smooth and can't see the seams?


General speaking, it is polished after stainless steel welding and then polished again and again. After learning information about the Chicago Cloud Gate, we can take a look at the stainless steel sculptures in Shenzhen Museum of Contemporary Art and Urban Planning Exhibition, and compare the gaps at home and abroad. From the participants of the Cloud Gate project in Chicago, Cloud Gate was the first large mirror stainless steel welding project that the civil construction had done. Although the process was rather twisty, it took some detours, but it is still the classic in the field of art and technology. The experience in the process has also provided a great help for later projects. For example, the cloud sculptures in the Shenzhen Museum of Contemporary Art and the Urban Planning Exhibition Hall are larger than Cloud Gate in terms of volume, but they only require 1/N of the construction cost and cycle time. However, from the beginning, people did not set the goal to the standard of Chicago Cloud Gate. It was too expensive and time was too limited.

1.The difference in polishing degree between 1, 4k, 8k, 10k or 12k directly affects the cost and the overall structural design. Because the difference of requirements on plate thickness will lead to the difference of requirements on grinding quality and structural. 

2.Because of the large amount of mirror stainless steel, deformation control is a difficult task. It may be thermal expansion and contraction in a time then cracks on the grinded welding seam. 

3.About robot welding and polishing.

The site is basically hand-welded and polished. Of course, digital technology was still used a lot, especially for the previous optimization and shape forming.
