Duggan Manufacturing offers in house metallurgy services. Our A2LA accredited laboratory is where we certify all of our welds using microscopic cut and etch technology. Simply put, a weld is cut across the joint and then polished. Nitric Acid is added to the surface, which makes the weld and parent metal appear dissimilar to each other. This sample can then be placed under a microscope and the various parts of the weld can be measured to customer specifications.
Our met lab also has an electromagnetic tension and compression tester. We perform in house pull tests and can test yield and tensile on different types of materials. This piece of equipment and technology is a must and is required in order to accurately hot stamp parts and verify that the tensile and yield are within spec on the finished product.
