“…This shows that the weld metal exhibits bending strength as much as the base material. Therefore, weld metal is suitable for use in the field as base materials [25][26][27]. In the bending tests of M1, M2, M3, and M4 specimens joined by the robotic MAG welding method, no cracks that would affect the formability of the welded joint were detected.…”

In this study, S235JR structural steel samples in uncoated condition and coated (shop-primer) in different thicknesses were welded by MAG (Metal Active Gas) welding method, and the effects of these applications on the mechanical and microstructure properties of the material were investigated. In the experimental studies, the first specimen group were used without any sandblasting and coating application, the second group specimens were sandblasted at Sa 2 ½ degree, and 25 µm, 50 µm, and 75 µm coatings were applied to the specimens in the other group. Surface conditions and coating thicknesses were selected as the variable parameters. With the examination of the radiography films, it was observed that the surface conditions affected the welded joint. As a result of the study, it was observed that altered coating thicknesses caused defects in the welding zone. It was determined that the coating thickness partially affected the mechanical properties, and the highest hardness values occurred in the weld zone in all samples. Relatively low values were obtained in tensile, bending and Charpy impact tests performed on sample groups with 75 µm coating thickness. The results were verified by the surface fracture, SEM, and EDS studies.

In this study, it has been reported that Q345B steel combine with different steels using electric arc welding method and the mechanical properties were investigated. Produced by hot rolling processes, Q345B steel is a low-alloyed medium tensile strength and highly usable steel. The steel used contain less than 0.2% carbon and less than 0.55% silicon, chromium and nickel. In this study, Q345B steel generally used at low-pressure/temperature zones in thermal power plant (boiler wall etc.) is combined with 16Mo3 and P265GH steels. The Q345B steel is welded to make the mechanical properties easy to compare. After joining, specimens were collected from the welded areas and used in the preparation of mechanical and metallographic processes. In this process, all joints were subject to tensile, charpy, hardness and bending tests. In addition, the collection of macro images from welding were used in observation of transition zones which were operated. Electrodes with a basic character cover were used (E7018) as filler metal in the joining processes. All mechanical tests met the requirements of the relevant standards and all welds were identified as valid weld. Bu çalışmada Q345B çeliğinin farklı çeliklerle elektrik ark kaynak yöntemi kullanarak birleştirilmesi ve mekanik özellikleri incelenmiştir. Sıcak haddeleme işlemleri ile üretilmiş olan Q345B çeliği düşük alaşımlı orta gerilmeli mukavemet değerlerine ve oldukça fazla kullanım alanına sahip bir çeliktir. %0.2 den daha az karbon içeren bu çelik %0.55 den daha az oranlarda silisyum, krom ve nikel ihtiva etmektedir. Bu çalışmada, genel olarak termik santrallerde (kazan duvarı gibi) düşük basınç ve düşük sıcaklık alanlarında kullanılan Q345B çeliği; 16Mo3 ve P265GH çelikleri ile birleştirilmiştir. Mekanik özelliklerinin karşılaştırmasının kolaylıkla yapılabilmesi için Q345B çeliği aynı zamanda kendisi ile de kaynak edilmiştir. Yapılan birleştirmeler sonrasında kaynaklı bölgelerden numuneler çıkartılıp mekanik ve metalografik işlemler için hazırlanmıştır. Bütün birleştirmeler sırasıyla çekme, çentik darbe, sertlik ve eğme testlerine tabi tutulmuşlardır. Bunların dışında geçiş bölgelerini gözlemlemek için tüm kaynak dikişlerinden makro görüntüler alınmıştır. Birleştirme işlemlerinde dolgu metali olarak E7018 kalite bazik elektrot kullanılmıştır. Tüm mekanik testler ilgili standartların şartlarını sağlamış ve tüm kaynaklar geçerli bir kaynak olarak tanımlanmıştır.

In this study, S235JR structural steel with/without primer in different thicknesses has been welded with submerged arc welding and effect of primer coating on the mechanical and microstructural properties has been investigated. During the study two different batch of test samples has been prepared, both are sand blasted to Sa 2 ½ and one of the batches has been covered with shop primer to 25 µm, 50 µm and 75 µm thicknesses. While carrying out analysis, surface texture and coating thickness has been designated as variables. It has been concluded that, 75 µm covered samples have yieded welding defections. Additionally, it has observed that coating thickness had a partial effect on mechanical properties of the material as highest hardness measurements has been observed at weld zones. Lastly, tensile, bending and impact tests has been performed, composite surface of failure has been analysed and only 75 µm covered sample plates has yielded non confirming results.
