| | | Overview The use of proper filler material is a major factor in the successful joining of alloys to ensure the quality and integrity of a welded joint. When choosing the optimum filler alloy, both the base materials and the desired qualities and performance of the weldment must be carefully considered. Once the metallurgical engineer has specified the iller material for a given application, many users simply depend upon their supplier to provide the correct alloy as marked. Unfortunately, mistakes and mix-ups in this material can and do happen. In some industries, a mix-up in the weld material will simply degrade the quality of the inal product. In others, such as petrochemical piping systems or aerospace applications, the consequences of using the wrong iller material can range from costly to disastrous, and may involve loss of property, loss of revenue, and even loss of life. Positive material identification (PMI) using handheld x-ray fluorescence (XRF) has become essential for verifying weld materials and inal joints at various stages of the use cycle, including incoming material inspection, in-process veriication, and inal product inspection. | | |
