Abstract
Penelitian ini mengevaluasi distorsi pada sambungan fillet weld untuk perbaikan bracket kapal menggunakan pendekatan Finite Element Analysis (FEA) dan eksperimen. Tujuan utamanya adalah menyelidiki pengaruh variasi urutan pengelasan terhadap distorsi, serta membandingkan hasil FEA dengan eksperimen pada sampel bracket kapal yang sama. Metode penelitian melibatkan pemodelan struktur menggunakan ANSYS dan eksperimen pengelasan dengan berbagai urutan. Data diperoleh dari WPS (Welding Procedure Specification) di galangan XYZ. Hasil penelitian menunjukkan bahwa variasi urutan pengelasan secara signifikan mempengaruhi distorsi. Urutan Continuous Welding menghasilkan distorsi 3.80 mm pada titik B dengan rata-rata distorsi sebesar 3.16 mm, Pada variasi intermittent welding sebesar 3.56 mm pada titik B dengan rata-rata distorsi sebesar 2.94 mm. Hasil FEA konsisten dengan eksperimen, menunjukkan validitas pendekatan simulasi. Urutan pengelasan paling optimal dalam FEA adalah urutan 5 dengan distorsi paling tinggi sebesar 3.56 mm berada pada titik C, dan distorsi minimum sebesar 2.51 mm pada titik F dengan rata-rata distorsi sebesar 3.09 mm. Intermittent welding ditemukan sebagai metode yang menghasilkan distorsi paling minimal. Penelitian ini menyimpulkan bahwa variasi urutan pengelasan mempengaruhi distorsi dan FEA dapat diandalkan untuk memprediksi distorsi. Temuan ini dapat digunakan untuk mengoptimalkan proses pengelasan dan meningkatkan kualitas perbaikan bracket kapal.

This research evaluates distortions in fillet weld joints for ship bracket repair using Finite Element Analysis (FEA) approach and experiments. The main objective is to investigate the influence of welding sequence variations on distortions, and compare the FEA results with experiments on the same ship bracket samples. The research method involves structural modeling using ANSYS and welding experiments with various sequences. Data were obtained from the Welding Procedure Specification (WPS) at XYZ shipyard. The research results indicate that welding sequence variations significantly affect distortions. The Continuous Welding sequence results in 3.80 mm distortion at point B with an average distortion of 3.16 mm, while the intermittent welding variation results in 3.56 mm distortion at point B with an average distortion of 2.94 mm. The FEA results are consistent with the experiments, demonstrating the validity of the simulation approach. The most optimal welding sequence in FEA is sequence 5 with the highest distortion of 3.56 mm at point C, and the minimum distortion of 2.51 mm at point F with an average distortion of 3.09 mm. Intermittent welding is found to be the method that produces the least distortion. This study concludes that welding sequence variations affect distortions and FEA can be relied upon to predict distortions. These findings can be used to optimize the welding process and improve the quality of ship bracket repairs.
