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.
