Weld Re-Entrant Angle

[Sankepalli R.S.Reddy]

Dear friends,

 

What is Weld Re-Entrant Angle and its significance related to quality of Butt and fillet welds?

 

Thanks and regards

check above document page 13/14 (no problem as long as weld is merged into the base metal)

[Landon, David]

Weld re-entrant angle is an alternative way to control the detrimental effects of excessive convexity of weld reinforcement.  Maximum convexity is often specified by a dimension that is difficult to measure.  In addition, the remedy that is frequently practiced to removed excessive convexity is the grinding of the top surface of the weld below the maximum specified height.  This does nothing to the critical issue which is the angle at the toe of the weld in relationship to the base metal.  This angle is the area of high stress which is what is really trying to be controlled.

 

By specifying a minimum weld re-entrant angle, the engineer is controlling the actual discontinuity and something that can be measured in the field.

 

Another name for re-entrant angle is "Toe Angle".
