The supervisor in charge should determine the best and safest means available to make the repair and then request inspection by the ACCo welding inspector as soon as possible. If the inspector determines that upgrading of the repair is necessary, it should be done at the next scheduled system shutdown.
C. Welding Procedures and Welder Qualifications
All welding procedures and qualifications of welders or welding operators will be per ASME, Section IX; AWS D1.1; or API 1104, latest revisions, depending on the class of service. Any essential variable changes from a qualified procedure will require additional new procedures.
Vendors doing work for Coors Industries will establishtheir own welding procedures per one of the above codes.The vendors procedures must be approved by The CoorsBrewing Company Welding Q.C. Manager.
The Welding Procedure Specifications (attachment 2) indicated on drawings have been prepared and qualified by Adolph Coors Company. These are the Welding Procedure Specifications which would be used by Adolph Coors Company and are valid only when applied by Adolph Coors Company. When these Welding Procedure Specifications are made available to other organizations, it is for reference only and with the express understanding that Adolph Coors Company assume no other responsibility for their use by others. Welding Codes require that both the Welding Procedure and the welder performance be qualified and documented by the organization applying the procedures.
Welding procedures and test data should be recorded on a "Procedure Qualification Record" form, or equivalent regardless whether the procedure is used by Adolph Coors Company or some other organization. A copy of the Procedure Qualification Record, including procedure sketches, should be available to the Coors Welding Inspector.

The welding parameters for each procedure should be listed in a document known as a "Welding Procedure Specification" form, or equivalent, regardless of whether the welding procedure is used by Adolph Coors Company or some other organization.
A copy of the Welding Procedure Specification should be available to the welder or welding operator and to the Coors Welding Inspector.
Welders or welding operators qualification test should be recorded on a "Manufacturer's Record of Qualification" form, or equivalent, regardless of whether the welder or welding operator is welding for Adolph Coors Company or some other organization. This record shall be available to the Coors Welding Inspector.
D. Welder Stamps
Welders will be assigned letter or number designations for identifying his welds. Welds on pressure vessels, boilers and piping systems are required to be stamped, stencilled or a written record maintained. Other welds may require stamping at the option of the welding inspector.

3.03 WELDING QUALITY CONTROL
See attachment 1 for the following quality control items:
1. Inspection methods.2. Responsibilities of The Welding Department.3. Supervisors Welding Quality Control Program.
ATTACHMENT 1
COORS WELDING QUALITY CONTROL PROGRAM
OBJECTIVE
The purpose of the Coors Quality Control Program is to insure welds are being made that meet or exceed the basic minimum requirements of the governing code per Engineering Specification No. 05060.
INSPECTION
Four types of nondestructive examination are used depending upon the inspection required. The examination methods are visual examination, dye penetrant, magnetic particle and spot or complete radiography. Visual and radiography are the most common methods used due to the variety of defects that can be detected. The dye penetrant and magnetic particle tests are valid for defects open to the surface.
RESPONSIBILITIES OF THE WELDING DEPARTMENT
The basic duty it to constantly monitor the field and shop welding to ensure that minimum code requirements are being met or exceeded. This is accomplished by communicating with job supervision to determine where welding is being performed and applying the appropriate inspection method. The Welding Department is responsible for qualifying new procedures when required by job needs, administering qualification tests to welders and reports and record keeping.

2. Supervision is responsible for checkout of welders prior tostart of job and request of welders if necessary. If additional training is needed, supervision shall request assistance from the Training Department.
3. Supervision shall insure that the welds are being made by the procedures called out on the drawings. Supervision may contact welding Q.C. for approval of alternate procedures where situation dictates.
4. Supervision should meet with Welding Q.C. or inspector to keep them informed of inspection needs.
5. Supervision shall insure that only qualified welders are welding.
6. Supervision should contact Welding Q.C. for assistance in any problem areas.
7. Supervision shall insure that a copy of the appropriate welding procedure specification (WPS) is available for review by the welders. All WPS copies are contained in this manual.
