30、plicing is done torepair a wire break without removing the wire from the process line. The sampleshall be tested for alloy identity prior to release for shipment.3.3.5.1 Ends of the coil. Both ends of each coil, drawn to finish size,shall be tested for alloy identity (see 4.6.4) before rewinding, sp
31、ooling, orstraightening and cutting into rods or electrodes.3.3.5.1.1 Continuous process operation. For continuous process operationwhere rod coil is drawn to finish size, straightened and cut to length withoutremoval from the machine, both ends of each rod coil shall be sampled for alloyidentity te
32、st immediately prior to the start of the continuous processingoperation. The sample shall be tested for alloy identity prior to release forshipment.3.3.5.1.2 Spliced rod coils. When rod coils are to be spliced duringcontinuous processing operations, each end of each rod coil to be spliced shallbe al
33、loy identity sampled just prior to splicing. The sample shall be alloyidentity tested prior to release for shipment. In addition, the leading end ofthe first coil and the tail end of the last coil for each continuous process runshall be alloy identity tested. When alloy identity testing is accomplis
34、hed inaccordance with 3.3.5.1.1, these requirements are met as well.3.3.5.2 Marking after tests. When specified (see 6.2), each electrode orrod shall be tested for alloy identity in accordance with 4.6.4 after finalmarking (see 5.2).
