Abstract
Welding induced distortion remain persistent problems leading to the inferior on Product Quality. The study is to investigate on welding induced angular distortion due to effect of anisotropy properties of the As-rolled C-Mn plate. The outcome could enhance the minimum distortion while cutting the raw material on rolling direction for fabrication process. The Anisotropy properties of the base metal were analyzed with along and transverse to rolling direction through microstructure examination, hardness measurement and mechanical properties. Microstructure contains coarse grains of pearlite and ferrite in transverse to rolling, whereas fine grains along the rolling. Hardness was 80 and 84 HRB along and transverse to rolling respectively. A weld bead was laid on the plate’s substrate with along and transverse to the rolling and angular deflections were measured with a dial gauge indicator. Finite element analysis (FEA) was carried out to evaluate the angular deflection on both the rolling. From the experimental results, the anisotropy properties of the as-rolled plate had influenced on angular deflection and indicating with good agreement with FEA.
