7. Summary of Tests
7.1 Chemical analysis of the solid electrode, rod, or strip is the only test required for classification of these product forms under this specification.
7.2 Chemical analysis of a fused sample of composite or stranded electrode, rod, or strip is the only test required for classification of these product ftrms under this specification. See Annex Clause A5, Preparation of Samples for Chemical Analysis.
8. Retest
If the results of any test fail to meet the requirement, that test shall be repeated twice. The results of both reests shall meet the requirement. Material for retest may he taken from the original test sample or from a new sample. Retest need be only for those specific elements that failed to meet the test requirement.
If the results of one or both retests fail to meet the requirement. the material under test shall be considered as not meeting the requirements of this specification for that classification.
In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the samples or in conducting the test, the test shall he considered invalid, without regard to whether the test was actually completed, or whether test results met, or failed to meet, the requirement. That test shall he repeated, following proper prescribed procedures. In this case, the requirement for doubling of the number of test samples does not apply.
9. Chemical Analysis
9.1 A sample of the tiller metal, or the stock from which i is made in the case of solid electrodes or rods, or a fused sample shall be prepared for analysis. See Annex Clause A5, Preparation of Samples for Chemical Analysis, for several possible methods.
9.2 The sample shall be analyzed by acceptable analytical methods capable of determining whether the composition meets the requirements of this specification. In case of dispute, the referee method shall be ASTM E 353.
9.3 The results of the analysis shall meet the requirements of Table I for the classification of the filler metal under test.
10. Method of Manufacture
The welding rods, strip, and electrodes classified according to this specification may be manufactured by any method that will produce materials that meet the requirements of this specification.
11. Standard Sizes and Shapes
11.1 Standard sizes for filler metal (except strip electrodes) in the different package forms (straight lengths. coils with support, coils without support, and spools) shall be as shown in Table 2.
11.2 Standard sizes for strip electrodes in coils shall be as shown in Table 3.
12. Finish and Uniformity
12.1 All filler metal shall have a smooth finish that is free from slivers, depressions. scratches, scale, seams, laps (exclusive of the longitudinal joint in metal cored filler metal), and foreign matter that would adversely atTect the welding characteristics, the operation of the welding equipment. or the properties of the weld metal.AWS A5.9/A5.9M pdf download.
