Questions regarding the equipment installation shims
Thread Content
What should be done if the shims used for installing the columns are wider than the bottom plate of the columns after installation? How many shims can be used at most? Should the shims be spot-welded together after installation? Can the shims be welded to the equipment base?
In accordance with the equipment installation specifications, each set of shims shall not consist of more than 4 layers; the height of a shim set should be between 30 and 70 mm. The shims must be arranged neatly, with a 0.05 mm feeler gauge inserted on both sides to a depth not exceeding 1/4 of the shim’s length, leaving 10 to 20 mm of the base exposed.
Thank you for the answer. There is one more question: is welding required after installation, and to what extent does welding need to be done?
Spot welding is required to prevent the shims from shifting or moving.
