Can anyone help me?
Where and on which standard is explained in the text on the maximum oscillation of the electrode which is 3 times??
and what is the maximum oscillation of the width of the weld for GMAW and FCAW?? and which standard is written.
Please help me with this
Also please ask any member can help me in doubt.
thank you
oscillation (traverse speed, length, and dwell time)
Your limitations are based on your approved weld procedure
from AWS D1.1/D1.1M:2010 page 146
Table 4.7 PQR Essential Variable Changes Requiring WPS Requalification for ESW or EGW
[B]Filler Metal Oscillation[/B]
6) A change in oscillation traverse speed> 10 ipm (4 mm/s)
7) A change in oscillation traverse dwell time> 2 seconds (except as necessary to compensate for joint opening variations)
8) A change in oscillation traverse length which affects by more than 1/8 in [3 mm], the proximity of filler metal to the molding shoes
thank you
