Factors such as the design of welded connections, workmanship, welding procedure, welding operator qualification, and inspection requirements are covered in this code. Previous to the 1994 issue of this code, it also specified the tensile strength, yield strength, elongation, and impact requirements for the low alloy flux cored electrodes, since no AWS Filler Metal Specification existed for these electrodes. It is required that the user (contractor or fabrica- tor) conduct tests to show that the low alloy weld metal would meet the mechanical proper- ties mentioned above per the code.
