Abstract

The growth and development of technology in the construction sector which is increasingly advanced and rapid, cannot be separated from the process of joining similar metals or joining dissimilar metals. This dissimilar welding uses AISI 1045 stainless steel and SS 304 carbon steel with a size of 200 x 200 x 6 mm. The welding method uses GTAW with ER 309 L filler metal with a diameter of 2.4 mm. Dissimilar welding aims to understand the mechanical properties affected by heat input. This study varies the heat input of 1.08 kJ / mm and heat input of 0.83 kJ / mm. The tests carried out were microstructure observations, tensile tests and hardness tests. The results of the tensile test all fractures occurred in the SS 304 base metal with an average value of 886 MPa. The results of the hardness test showed that the fusion line point had a higher hardness value compared to the base metal. In the observation of the microstructure of the SS 304 fusion line area, it has ferrite and pearlite phases, for the weld metal area it has ferrite, austenite and dendritic phases, in the AISI 304 fusion line section it has ferrite and austenite phases. The effect of heat input can be concluded that heat input affects the HAZ and fusion line due to the increasing hardness value.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh proses post weld heat treatment (PWHT) terhadap kekuatan tarik pada pengelasan material similar atau sejenis. Penelitian ini menggunakan metode eksperimen. Sampel dalam penelitian ini adalah pengelasan material AISI 1045 menggunakan metode Metal Inert Gas (MIG) dengan penambahan PWHT. Proses pengelasan MIG menggunakan variasi kuat arus sebesar 80 A, 90 A, dan 100 A. Sedangkan proses PWHT menggunakan variasi suhu yaitu 600°C, 700°C, dan 800°C. Analisis data menggunakan metode deskriptif kuantitatif dari hasil pengujian tarik. Hasil penelitian menunjukkan bahwa: (1) Pada kekuatan tarik PWHT 600°C sebesar 893.33 MPa memiliki nilai paling baik atau lebih tinggi dibandingkan dengan PWHT 800°C, dan PWHT 700°C dengan nilai sebesar 680,88 MPa dan Non PWHT material memberikan nilai sebesar 658.66 MPa. (2) temperatur PWHT dapat mempengaruhi kekuatan tarik. (3) Perlakuan pengelasan dengan kuat arus sebesar 100 A dan PWHT 600°C pada material AISI 1045 adalah yang paling optimal, karena memiliki nilai kekuatan tarik tertinggi.
