By: Laboratory Testing Inc. · AWS A4.4 M · MIL-E-23765/ · EB 4906 Rev A Moisture Analysis is a test frequently ordered by businesses that rely on precision welding or that purchase materials known to contain moisture. Flux coated weld wire can absorb moisture if not properly stored in a humid environment. Prior to welding, moisture analysis can determine the presence of moisture, which can lead to porosity. Porosity is contamination of weld metal caused by trapped hydrogen as moisture breaks down during heating, leaving round holes in the weld bead. Porosity can weaken the weld, and depending on the welding code or standard, porosity might cause rejection of a weld. Residual moisture can be found in many inorganic materials, but it is important for buyers to know they are not paying for unwanted moisture. Here again, moisture analysis solves the problem by letting the buyer know the percentage of total weight that is attributed to moisture. The Leco’s state-of-the- Laboratory Testing Inc’s full-service Chemistry Lab also offers a range of services including ICP analysis, AES and wet chemistry to identify and quantify major and minor elements for customers wanting to check sample purity. LTI can also examine flux-cored wire for rust caused by exposure to moisture, which can be detrimental to weld quality. About Laboratory Testing Inc. - Laboratory Testing Inc.
