Re: [MW:4846] Query for incomplete welding

Dear azmi, 

To answer your question, no 1 is more accurate.

The name full penetration calls for the penetration on the root side. Normally if the welding design thickness weld calls for 10mm, it is not wrong for the welder to fill up the groove up to the 12 mm of the plate thickness. This gives a good blend between the weld face and the groove edge of the face (toe area). If welding is not a possible solution, then the remaining groove edge has to be grind  blend such as to eliminate sharp notches which weakens the weld.

Dear All,
 
Please clarify below points.
 
 
The designed thickness for a plate to plate welding is 10 mm and actual thickness used in the production is 12 mm. welding requires Single side full penetration weld.
 
1) considering the above case is it acceptable  if  welding groove is filled  upto 10 mm thickness only considering complete penetration on root side.
 
2) Is it acceptable if complete 12 mm thk groove is filled and we have incomplete penetrartion of 2 mm on root side.
 
Please give Code reference(if any).
 
 
Thanks & Regards
