A case study on achieving defined Welding Penetration

In this paper, welding parts fitment are designed and welding parameters, affecting parameters and residual stresses, such as welding torch approach in fixtures and proper part fitment in fixture for controlling longitudinal stresses are taken into consideration Weld sequence is effective on distortions. First weld seam on the part creates preheating effect on the next weld seam and affect penetration. After analysis of fixture design, inversely proportional to weld angle, penetration increased by increasing heat input, as expected. The various improvements have been done in welding process & in welding parts conditions to increase penetration in welding parts. This Work was done for increasing quality level of welding fixtures.
