Welding Inspector & WPS (PART 7)

PART 7: ELECTRICAL CHARACTERISTICS VARIABLES

26

Key Notes:

* In case of WPS with CVN impact test and no PWHT requirement:

As common sense dictates, the Welding inspector will take a look on Weld bead profile firstly. The increase of Weld bead (Width) or reduction of R.O.L (Run out length) which makes toughness deduction.

 For the FCAW/GMAW: the weave width range is about 2.5x-5x core diameter.

From the Welding engineer point of views, the limitation of welding weaving bead should to be mentioned wisely as below example for SMAW:

Note: During running pWPS-CVN, the weld bead width (each pass) has to be carefully recorded.
