Entering the Weld Parameters
The following describes the parameters that are set on the
SWS front panel as well as briefly discussing how the
parameters are determined.
Using a Weld Procedure Guideline
There are several reference weld procedure guidelines
included in Appendix I,
Weld Procedure Guidelines,
of
this manual. If assistance is needed in obtaining more
Weld Procedure Guidelines, please provide your Swagelok
representative with your specific requirements.
The weld procedure guideline listed in Table 3-9 is based on
1/2 in. tubing with a 0.049 in. wall thickness.
