The primary disadvantage of this joining process however is that all of these techniques require a high heat to melt the components together and cause distortion. One such material that used are ASTM A36. to counter this problem is making a support to adjust the material prior welding that called Jig/Fixture since welding distortion occur when welding process it made. with the purpose to maintain the material to be adjust in a fixed position so that even after weld its still maintain its designated position. so it need more study for consideration during the tool design phase, and with that a computerized analysis using Finite Element Method (FEM) program to help knowing deformation pattern, thermal response of T-Joint Weld under applied load that can obtain approximated result. The result of the analysis with T-Joint A-36 material with 277.41 MPa is the stress value (von mises). The material type of ASTM A-36 has a deformation value of 0.77 mm. In the meantime, 15 is the safety factor value for the material type of mild steel. Thus, substance with a safety factor value of ≥1, mild steel material is deemed safe to employ as a supporting fixture in this design.enTECHNOLOGY::Engineering mechanics::Mechanical manufacturing engineeringTECHNOLOGY::Industrial engineering and economy::Manufacturing engineering and work sciencesTECHNOLOGY::Engineering mechanicsTECHNOLOGY::Engineering mechanics::Solid mechanicsArticleNIM4412001026NIDN0029048902NIDN0003048408KODEPRODI36305#TEKNOLOGI REKAYASA KONSTRUKSI PERKAPALAN
