An comparative study was made of microstructure and mechanical properties of steel constaining Ni of 9% in different heat treatments. Shielded metal arc welding (SMAW) was employed as jointing technique. Double normalizing and tempering (NNT) and quenching, intercritical quenching and tempering (QLT) were applied as the heat treatments. Instrumented impact and tensile tests were performed between 20°C and 196°C. The results show that both the microstructure and mechanical properties of base and weld metals in QLT solution turn out to be the optimal.

<p><strong>ABSTRACT</strong></p><p>            <em>Welding is the common method for joining material used in construction and industrial applications. Variable of welding process is the most important factor affected into the mechanical properties of welded materials.  This study used Shielded Metal Arc Welding (SMAW) as welding method. SMAW method use flux to protect the metals. Sample preparations were done to make the V groove using 45ᵒ and 60ᵒ as angle of welding. Variations of heat input also were used as 75A, 85A, and 95A. Characterization of mechanical properties was analyzed by tensile test and macroscopic analysis showed the different area after welding. Based on the following experimental result, the highest ultimate tensile strength was obtained by sample  prepared 45ᵒ of V groove angle and 85A of current which is 518 N/mm² and got 449 N/mm² of  yield strength. Increasing current caused the wider weld pool in the sample surface and showed clear grove shape of welded sample.</em> </p><p><strong>ABSTRAK</strong></p><p>Pengelasan merupakan metode penyambungan material yang secara umum digunakan dalam  bidang konstruksi maupun aplikasi di industri. Parameter pengelasan perlu diketahui karena berpengaruh terhadap sifat mekanik yang dihasilkan material setelah proses penyambungan Pada penelitian ini, proses pengelasan yang digunakan adalah <em>Shielded Metal Arc Welding</em> (SMAW). Pengelasan SMAW menggunakan fluks sebagai pelindung logam. Preparasi sampel dilakukan dengan pembuatan sudut pengelasan/sudut kampuh 45ᵒ dan 60ᵒ.  Arus pengelasan bervariasi sebesar 75A, 85A, dan 95A. Karakterisasi sifat mekanik diperoleh dari pengujian tarik dan pengamatan makro untuk mengetahui perubahan daerah yang berbeda setelah dilakukan pengelasan. Berdasarkan hasil pengujian, spesimen benda uji dengan sudut pengelasan 45ᵒ besar beban maksimal (σu) terjadi pada arus 85 A yaitu sebesar 518 N/mm² dan memiliki tegangan luluh paling tinggi yaitu  449 N/mm². Kenaikan arus pengelasan menyebabkan weld pool yang lebih besar dan permukaan penampang samping terlihat jelas bentuk kampuh sampel pengelasan.</p>

And Performance

This study presents the performance evaluation of reworked welded joint that have weld imperfections which may result the strength of the structures. Tensile, bending and shear tests have been performed to evaluate the performance and reliability of reworked joint. Their effects on the quality and performance of the reworked welded joint are depend on the requirements of the structure in use. This study is providing detailed examination of the mechanical properties of the carbon steel reworked welded joint by using shielded metal arc welding (SMAW) techniques.

Welding Position

In this study the effects of two welding positions included in flat and upward vertical on the mechanical properties and microstructure of high strength weld metal deposited with shielded metal arc welding (SMAW) using an electrode of ASME SFA 5.5-96 E9018B3 type have been investigated. The aim of the present work is to study the effects of these two welding positions for a weld metal alloyed with 1%Mo, 2%Cr, 0.79%Mn, and 0.08% C in the stress relieved condition. For studying mechanical properties Tensile, Impact and hardness experiments have been conducted; meanwhile chemical analysis and microstructure studying have been carried out on specimens. The results show that welding position does not have any significant effect on tensile and hardness of the weld metal but in vertical position welding metal toughness is lower than toughness in flat position in all temperatures. Transition temperature of ductile fracture to brittle fracture is -50 °C for E9018B3 in welding of high strength micro alloyed steels.
