Abstract
In the present work, gas metal arc welding (GMAW) and adhesive bonding have been considered as mild steel notch filling techniques. Static as well as dynamic characteristics of filled and unfilled specimens, at different notch angles are assessed and reported.
The present work showed that adhesive bonding is a far superior notch filling technique, when compared with gas metal arc welding due to the absence of distortions, minimum or no metallurgical damage, added to the good joint sealing and better appearance. The present work suggests that metals be cut before repair to a notch angle of 60
°
, since maximum ultimate strength (546 MPa) was obtained at a 60
°
notch angle.
