Coupon Testing at the Shrine

CHICAGO, IL – Coupon Testing was done yesterday at the Shrine. What is Coupon Testing?

Coupon testing is essential in the design of renovations of steel in historic buildings to understand the yield strength of the steel and the chemical content to determine the feasibility of welding to the new steel. When the carbon content of the existing steel is known the new steel can be made to make welding feasible.
