A Study of Effect of Groove Angle on Angular Distortion and Impact Strength in Butt Welds

Welding is an area in which technological developments out match the developments in its science base, which is primarily driven by the phenomenal industrial demand for welded structure. Reliability, Reproducibility and Viability requirements are forcing Technologists to look at weld defects such as distortion, hot cracking, in a systematic and logical approach than on adhoc basis. Distortion is an unwanted physical change from specifications in a fabricated structures is caused by non-uniform expansion and contraction of the weld metal during heating and cooling cycle of the welding process many factors viz., material properties, welding process and procedures adopted make accurate prediction of distortion difficult. Groove angle was taken to analyze angular distortion and impact strength in butt weld joints. In this paper detailed discussion is carried on in controlling the angular distortion by selecting proper angle in the shielded metal arc welded joints and by varying the same factor the impact strength of the joint was also evaluated.
