Procurement Guidelines
1. Scope
3.3 In the case of distributors who receive electrodes in bulk and package them for distribution, or who repackage under their own label, the distributor shall maintain an adequate control system to ensure that the package contents are traceable to the original manufacturer’s records.
This document, together with an AWS filler metal specification, is intended to describe a uniform method for providing those specific details needed for filler metal procurement which consist of the following: (1) The filler metal classification (selected from the pertinent AWS filler metal specification) (2) The lot classification (selected from Section 5 of this document) (3) The level of testing schedule (selected from Table 1 and Section 6, Level of Testing, of this document)
4. Definitions and Identification of Materials 4.1 Introduction. In production, the components of the fiíler metal are divided into discrete, predetermined quantities so that satisfactory tests with a sample from that quantity will establish that the entire quantity meets specification requirements. These quantities, known by such terms as heats, lots, blends, batches, and mixes, vary in size according to the manufacturer. For identification purposes, however, each manufacturer assigns a unique designation to each quantity. This designation usually consists of a series of numbers or letters, or combinations thereof, which will enable the manufacturer to determine the date and time (or shift) of manufacture, the type and source of the raw materials used, and the details of the procedures employed in producing the filler metal. This designation stays with the filler metal and can be used to identify the material later, in those cases in which identification is necessary.
2. Certification By affixing the AWS specification and classification designations to the packaging, or the classification to the product, the manufacturer certifies that the product meets the requirements of that :pecification.
3. Manufacturer’s Quality Assurance System 3.1 The certification of the product is accomplished through a quality assurance program, by which the manufacturer verifies that the product meets the requirements of this specification. Such a program includes planning, documentation, surveillance, inspection, testing, and certification of the test results. It also includes control of the inspection and measuring equipment, as well as control of any nonconforming material. It involves auditing of the activities and provides for developing and implementing any corrective action that may become necessary.
4.2 Definitions. The terms dry batch, dry blend, wet mix, and heat, as they are defined and used in this document, refer to discrete quantities of the components used in producing a lot of filler metal. The definition of these terms and the considerations that must be given to the identification of the components to which they apply are as follows.
3.2 It is the responsibility of the purchaser to review the quality assurance program of the manufacturer for conformance to the purchaser’s specific requirements.
4.2.1 Dry Batch. A dry batch is the quantity of dry ingredients mixed at one time in one mixing vessel.

2
Liquid binder, when added to a dry batch, produces a wet mix. A dry batch may be divided into smaller quantities, in which case the addition of the liquid binder produces as many wet mixes as there were smaller quantities. --``,``-`-`,`,`,`,`---
4.2.2 Dry Blend. A dry blend consists of two or more dry batches from which quantities of each are combined proportionately, then mixed in a mixing vessel. This produces a larger quantity in which the ingredients are as uniformly dispersed as they would have been had the entire quantity been mixed together at one time in one large mixer. A dry blend, as in the case of a dry batch, may be used singly or divided into smaller quantities which, when the liquid binder is added, produce one or more wet mixes. 4.2.3 Wet Mix. A wet mix is the combination of liquid binder and a dry batch or a dry blend, or a portion thereof, mixed at one time in one mixing vessel. 4.2.4 Heat. A heat of metal for consumable inserts, brazing and braze welding filler metals, solid electrodes and rods, core wire for covered electrodes, and the sheath (strip or tubing of composite electrode wire and rod) is defined by one of the following, depending on the method of melting and refining of the metal. 4.2.4.1 Where slag-metal or gas-metal reactions occur in producing the metal (e.g., open hearth, electric arc, basic oxygen, argon-oxygen), a heat is the material obtained from one furnace melt. 4.2.4,2 Where significant chemical reactions do not occur in producing the metal (e.g., induction melting in a controlled atmosphere or in a vacuum), a heat is an uninterrupted series of melts from one controlled batch of metals and alloying ingredients in one melting furnace under the same melting conditions. Each melt shall conform to the chemical composition range approved by the purchaser of the material (Le, the producer of the filler metal). 4.2,4.3 In processes involving continuous melting and casting (e.g., consumable electrode remelt), a heat is an uninterrupted series of remelts in one furnace under the same remelting conditions using one or more consumable electrodes produced from a heat, as defined in 4.2.4.1 or 4.2.4.2. Each remelt shall conform to the chemical composition range approved by the purchaser of the material (Le., the producer of the filler metal).
identified by heat number shall consist of material from a single heat of metal. 43.2 Controlled Chemical Composition. Solid wire, electrode core wire, rod, strip, consumable inserts, and brazing and braze welding filler metal identified by controlled chemical composition, rather than by heat number, shall consist of mill coils of one or more heats from which samples have been taken for chemical analysis.’ The results of the analysis of each sample must be within the manufacturer’s composition limits for that material. Coils from mills that do not permit spliced-coil practice need be sampled on only one end. Coils from mills that permit spliced-coil practice must be sampled on both ends and shall have no more than a single splice per coil, 4.4 Identification of Covering Mix 4.4.1 Wet Mix. Covering identified by wet mix shall consist of a single wet mix for each lot of electrodes. 4.4,2 Controlled Chemical Composition, Covering identified by controlled composition (rather than by wet mix) shall consist of one or more wet mixes and shall be subjected to sufficient tests, both before and after it has been applied to the core wire, to assure that all wet mixes within the lot are equivalent. These tests shall include chemical analysis, the results of which must fali within the manufacturer’s acceptance limits. The identification of the test procedure and the results of the tests shall be recorded. 4.5 Identification of Core Ingredients 4.5.1 Dry Blend. Core ingredients identified by dry blend shall consist of a single dry batch or dry blend. 4.5.2 Controlled Chemical Composition. Core ingredients identified by controlled composition consist of one or more dry blends and shall be subjected to sufficient tests to assure that all dry blends within the lot are equivalent. These tests shall include chemical analysis, the results of which must fall within the manufacturer’s acceptance limits. The identification of the test procedure and the results of the tests shall be recorded.

When required, alloy identity procedures shall be specified in Procurement Detail Forms using Item III, Other Requirements?
4. See Tables Al through A7 (in the Appendix) for Procurement Detail Forms and examples of their use.
8.2.1 Core Wire Alloy Identity. Each end of rod, wire, or strip to be spliced during processing shall be tested for alloy identity just prior to splicing at the process station, except when splicing is done to repair a wire break without removing the wire from the process line. Both ends of each coil drawn to finish size shall be tested for alloy identity prior to cutting into electrode core wire lengths. 8.2.1.1 Single Coil. For continuous process operations where a single rod coil is drawn to finish size, straightened and cut to length without removal from the machine, both ends of each rod coil shall be alloy identity tested immediately prior to the start of the continuous processing operation. 8.2.1.2 Multiple Coils. When multiple coils are to be spliced during continuous processing operations, each end of each coil to be spliced shall be alloy identity tested at the process station just prior to splicing. In addition, the leading end of the first coil and the tail end of the last coil for each continuous process run shall be alloy identity tested. 8.3 Responsibility for Compliance. Ail items shall meet all applicable requirements. The inspections set forth in this specification shali become a part of the manufacturer’s overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted for acceptance comply with all requirements of the contract. Sampling inspection, as part of the manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the customer to accept defective material.

Appendix
(This Appendix is not a part of ANSUAWS A5.01-93, Filler Metal Procurement Guidelines, but is included for information only.)
Al. Introduction
A7. In Table A6, the four examples demonstrate the manner in which different packaging, lot classification, supplementaldesignators, and testing requirements would be specified in a purchase order for 1000 pounds (453 kg) of 3/16 in. (4.8 mm) diameter E7018 electrodes. The differences are summarized
This guide is appended to the specification as a source of infomation; it is not mandatory and does not form a part Of the specification* Its purpose is to provide descriptive information and examples that will aid in the use of A5.01, Filler Metal Procurement Guidelines.
Example 1: The test and certification requirements specified are those the manufacturer of the electrodes uses as “standard practice” in the conduct of the manufacturer’s business (see Table 1in the body of this specification).
A2. General Information The general requirements, testing requirements and procedures, method of manufacture, identification, and packaging for filler metals are specified in the filler metal specification and are not intended to be duplicated or modified in this specification, except as the purchaser specifies. The complete list of filler metal specifications is given for reference in the back of this document. Those specifications, used in conjunction with these Procurement Guidelines, provide a basis for specifying in a procurement document the filler metal requirements in a precise, reproducible, uniform manner. The Forms in through A5 are suggested forms intended to serve as a check list for detailing filler metal requirements for procurement. They could also serve as a basis for efficient communication between departments within an organization (e.g., communication between welding or production departments and purchasing concerning the specific requirements for filler metal to be procured). Examples of the manner in which the Procurement Detail Forms might be used are given in Tables A6 and
Example 2: Requirements include 10 lb unit packages, a -1 (read as “dash one”) supplemental designator, and, for the lot shipped, a certificate showing the results of the chemical analysis, the tensile, impact, and soundness tests, and the moisture content of the covering (for lowhydrogen electrodes, as the filler metal specification requires). See Tables 1 and 2. The lot classification, in this case, is the manufacturer’s standard lot (see 5.1.1).
Example 3: Requuements include Ib unit packages, an H4 supplemental designator, and, for the lot shipped, a certificate showing the results of all tests ANSIIAWS A5.1 requires for the classification of E7018 electrodes. The of the lot in this case, is given in 5.1.3. Example 4: The requirements here are the same as in Example 3, except that the electrode length is 18 in. and the supplemental designator is H4R. The lot classification is as defined in 5.1.2 and the level of testing is that which the purchaser has specified in Item III, Other

Requirements. Those tests, in this case, would be the tests required for classification of the electrode, except that the mechanical property tests (strength and toughness) would be conducted on weld metal obtained from the test assembly after the assembly had been given a postweld heat treatment at 1200 & 2S°F (650 k 15OC) for 12 hours with the heating and cooling rates specified in Item III, Other Requirements. Table A7 demonstrates the use of the Procurement Detail Form for listing the requirements for obtaining straight lengths (rods) and spooled (electrode) aluminum filler metal to filler metal specification ANSI/AWS A5.10, Specification for Bare Aluminum and Aluminum Alloy Welding Electrodes and Rods. Example 5 is for rods and Example 6 is for spooled electrodes. In both cases, the tests to be conducted are those called for in Table 2, as indicated by Schedule I (see Table 1 for description). The tests for aluminum rods are different from those for aluminum electrodes, but no other requirements are specified in this case.
