“…Maka dari itu diperlukanlah suatu pengujian agar data yang dihasilkan bisa valid [5]. Tujuan dilakukannya pengujian adalah untuk menentukan kualitas produk-produk atau spesimen-spesimen tertentu, sedangkan tujuan pemeriksaan adalah untuk menentukan standar-standar kualitas tertentu atau tidak dengan kata lain tujuan pengujian dan pemeriksaan adalah untuk menjamin kualitas dan memberikan kepercayaan terhadap kontruksi yang dilas.…”

Shield Metal Arc Welding (SMAW) which is also called Electric Arc Welding is a welding process that uses heat to melt the base material or base metal and electrodes (fill material). Meanwhile, at the processing stage, the appropriate current strength will be selected to the working position. The purpose of this study was to determine the effect of welding current on the mechanical strength of AISI 1050 medium carbon steel. The currents used were 100 A, 125 A and 150 A. After doing research, SMAW welding on AISI 1050 medium carbon steel with variations in current affects the value tensile strength, stress and strain that occur after welding. As the results obtained are for welding currents with a current of 150 A having the highest tensile strength of 74.36 kgf/mm2, while for a current of 100 A having a tensile strength of 72.94 kgf/mm2, while the lowest value is at a current of 125 A which has a tensile strength of 51.45 kgf/mm2. , while the strain that occurs at a current of 100 A is 10.13%, while at a current of 125 A the strain that occurs is 5.27%, and at a current of 150 A that is 9.92%

“…Pengujian specimen hasil las dilakukan untuk menentukan kualitas pengelasan, bahwa spesimen tersebut sudah memenuhi standar-standar kualitas tertentu, agar dapat memberikan kepercayaan terhadap specimen yang di las (Akhyar et al, 2022). Cacat las yang masih terjadi dalam sistem produksi, mengakibatkan pemborosan pada material, waktu dan tenaga kerja yang lebih banyak (Sharma, 2022).…”

Welding is an important process in the manufacturing, metal and machinery industries, the welding results of students in the 1G Steel ST7 position are studied with the aim of identifying potential weld defects, determining root causes, evaluating and developing repair strategies to improve overall welding quality. The methods used in this research are qualitative and quantitative methods. Measuring welding dimensions with visual weld inspection, as well as liquid penetrant testing to identify weld defects. The data is processed using a Pareto diagram to determine the dominant types of defects that occur in the welding process. Once the dominant defect type is known, analysis is then carried out using the Fault Tree Analysis method. The results of the liquid penetrant test show that there are 8 types of weld defects with a total of 62 defects. In the FTA, basic events have been identified that contribute to the occurrence of weld defects, namely factors such as welding speed instability, incorrect current settings, and moist electrode. Regular evaluation, continuous monitoring and supervision during the welding process to reduce the risk of defects and improve welding quality

“…Welding is a reliable and efficient metal joining process that is widely used in the infrastructure and heavy equipment industries, such as steel bridge construction, shipbuilding and the installation of large pipelines [3][4][5][6]. High joint efficiency, ease of installation and low manufacturing costs are the advantages of this joining process [7][8][9][10][11]. Submerged arc welding is a fusion welding process used to produce machine parts and tools with basic surface properties such as corrosion resistance, wear resistance and pressure tightness [12].…”

Bu çalışmada, 10 mm kalınlığındaki ASTM A36 çeliği tozaltı ark kaynak yöntemiyle birleştirilmiştir. Farklı kaynak akımlarının kaynak bölgesine etkisi, tahribatsız ve tahribatlı muayene yöntemleriyle incelenmiştir. Kaynaklı birleştirmelerin tahribatsız incelemelerinde sıvı penetrant (SP), manyetik parçacık (MT), ultrasonik (UT) ve radyografik (RT) muayene yöntemleri kullanılmıştır. Kaynaklı birleştirmelerin makro-mikroyapı ve mekanik özelliklerini belirlemek için ise tahribatlı muayene yöntemlerinden optik mikroskop, mikrosertlik çalışmaları, çekme, eğme ve çentik darbe testleri uygulanmıştır. Tahribatsız muayene yöntemleri sonucunda; SP ve MT yöntemlerinde kaynak yüzeyinde herhangi bir süreksizliğe rastlanmamıştır. UT ve RT incelemelerinde ise 450 A ve 475 A kaynak akımında birleştirilen levhalarda kök nüfuziyet eksikliği gözlemlenmiştir. Tahribatlı muayene yöntemleri sonucunda; makroyapı incelemelerinde, 450 A ve 475 A kaynak akımlarında birleştirilen levhaların kök kaynaklarında eksik nüfuziyet gözlemlenmiştir. Mikroyapı incelemelerinde, kaynak metali-ITAB geçiş bölgelerinin birbirlerine benzer görüntüler sergilediği belirlenmiştir. Sertlik testlerinde sonucunda en yüksek sertlik değerleri, kaynak metalinden elde edilirken onu sırasıyla ITAB ve ana malzeme takip etmiştir. Çekme testleri sonucunda, 450 A ve 475 A kaynak akımlarında birleştirilen levhalarda kopma kaynak metalinde gerçekleşmiş diğer kaynak akımlarında ise kopma ana malzemede gerçekleşmiştir. Eğme testleri sonucunda, 450 A ve 475 A kaynak akımlarında birleştirilen levhalarda yırtılma ve çatlak tespit edilmiştir. Çentik darbe test sonuçları incelendiğinde, sıcaklık yükseldikçe tokluk değerlerinin arttığı tespit edilmiştir.
