6.4.2 Weld filler material and flux is inspected by the Quality Control Manager to ensure that<br />

it is properly identified with Heat Code information, meets the requirements of the<br />

Purchase Order and applicable material specifications, and is free from damage and<br />

defects. Materials which do not comply with the Purchase Order or material<br />

specifications, are not properly identified, or are damaged or defective are considered<br />

nonconformities and shall be returned to the vendor or processed as described in<br />

Section 5, Control of Nonconformities.<br />

6.4.3 All received and accepted weld filler materials and flux are placed in a designated<br />

storage area under the control of the Shop/Field Superintendent. All flux coated<br />

electrodes requiring temperature control by the manufacturer or Code are placed in<br />

holding ovens after opening of their containers. The electrodes are segregated in the<br />

ovens relative to their size and classification. Welding electrodes of different<br />

classifications or sizes are not intermingled in the oven. The ovens are maintained at<br />

temperatures in accordance with the manufacturer’s requirements or ASME Section II<br />

Part C.<br />

6.4.4 The Shop/Field Superintendent is responsible for the issuance of low hydrogen filler<br />

materials. These electrodes are issued for the duration of the welder’s shift and are to be<br />

stored in portable rod ovens issued with the low Hydrogen electrodes.<br />

6.4.5 The welder/welding operator shall return unused materials at the end of his shift. All<br />

material is examined for identification and condition, and low Hydrogen electrodes<br />

placed in the oven. Materials that are damaged or otherwise unfit for use are not used<br />

for Code work.<br />

6.5.0 WELDER/WELDING OPERATOR IDENTIFICATION SYMBOL<br />

6.5.1 Qualified welders/welding operators shall be assigned an identification number or<br />

symbol by the Quality Control Manager. The welder/welding operator shall record his<br />

identification symbol adjacent to all welds made by him, at intervals not exceeding 3<br />

feet. For ferrous materials ¼” and over in thickness and nonferrous materials ½” and<br />

over in thickness, he shall utilize a low stress stencil or vibroetcher issued by the<br />

Quality Control Manager. For identifying welds on materials in which the thickness is<br />

less than stated above the welder/welding operator shall mark his identifying symbol by<br />

vibroetching or another marking method acceptable to the Authorized Inspector.
