To develop a weld procedure guideline, follow these steps:
Locate the Example Weld Procedure Guideline Worksheet
found on page 5-9. Each of the following steps on pages
5-2 through 5-8 corresponds to the steps on the example
worksheet. After completing each step, verify the recorded
value on the example worksheet. A blank worksheet is
included on page 5-10 for you to use when creating your
own weld procedure guidelines.
The values in parenthesis ( ) in the procedure correspond to
the steps in the Example Weld Procedure Guideline
Worksheet found on page 5-9.
Determining the Work Specifications
1. Determine the outside diameter (1/2 in.) of the tubing
or fitting at the weld joint.
2. Determine the wall thickness (0.049 in.) of the tubing
or fitting at the weld joint.
3. Select the weld head model (CWS-5H-B).
4. Refer to the Electrode Selection Tables in Appendix C,
Electrode Selection Tables and Geometry . Select the
proper electrode (CWS-C.040-.605-P).
5. Refer to the Weld Head Arc Gap Gage tables in
Appendix E,
Arc Gap Gage Setting Tables
. Set the
arc gap (0.907 in.) in the arc gap gage with either a
caliper or micrometer.
Note: The electrode length and
diameter depend on the weld head
model and the outside diameter of
the components.
Note: Most applications use an arc
gap of 0.035 in. The proper arc gap
gage setting depends on the weld
head model and the outside
diameter of the components.
