“…In the fusion zone the hardness was found to be higher. Reference [13] have studied the effect of process parameters on austenitic stainless steel 304L such as arc intensity, applied load and welding duration on the mechanical characteristics of the weld joint. The results showed that the applied load seems to be the control factor of the mechanical characteristics of weld joint compared to the current intensity and welding duration.…”

Resistance spot welding is commonly used in sheet joining in the aerospace industry and automotive industry, because it has the advantage which is high-production assembly lines, high speed and suitability for automation. Resistance Spot Welding (RSW) is widely used for its low cost, simple mechanism, high speed and applicability for automation. It depends on the amount of current flowing and resistance of the base metal to produce the heat necessary to make the spot weld. There are various process parameters such as weld current, electrode force and, weld time which affects the weld nugget and its strength. So it is necessary to optimize the process parameters of resistance spot welding process. Therefore it is very important to understand the behavior of spot welds and their failure characteristics.

“…Pengelasan titik memiliki keunggulan dari sudut pandang ekonomi, di mana dapat diaplikasikan pada berbagai jenis material logam dan memiliki waktu siklus proses yang singkat [2]. Proses pengelasan titik sendiri merupakan suatu proses yang kompleks, melibatkan interaksi elektrik, panas, mekanik dan fenomena metalurgi, di mana setiap parameter proses memiliki pengaruh terhadap kualitas dan karakteristik hasil lasan [3][4][5]. Masalah yang sering dihadapi pada metode ini adalah kualitas hasil las atau nugget yang terbentuk.…”

AbstrakPengelasan titik (resistance spot welding) merupakan salah satu aplikasi pengelasan yang banyak dipergunakan didalam dunia otomotif. Pada proses pengelasan titik, elekroda sangat berperan sebagai penghantar arus untuk menyambung material yang umumnya berupa lembaran baja tipis. Penelitian yang dilakukan ini bertujuan untuk mengkaji pengaruh lapisan tipis timah putih (Sn) berbentuk lapisan intermetalik Cu 3 Sn di bagian ujung elektroda (electrode tip) dalam aplikasi pengelasan titik baja galvanis. Variabel utama yang diberikan pada penelitian ini adalah beda ketebalan lapisan tersebut. Hasil pengamatan dan pengujian menunjukkan bahwa pemberian lapisan intermetalik Cu 3 Sn pada ujung elektroda dengan ketebalan terbatas, khusus dalam penelitian ini kurang dari 1 µm, menghasilkan kuat tarik geser dan ukuran diameter nugget yang relatif sama (comparable) dengan nilai kuat tarik geser hasil las menggunakan elektroda tanpa lapisan intermetalik Cu 3 Sn. AbstractIntermetallic Cu 3 Sn Phase Layer on Electrode's Tip of Galvanized Resistance Spot Welding. A resistance spot welding method is commonly used in automotive industries application. In a resistance spot welding method, the copper electrode has a significant role as an electric current carrier for joining thin metal sheet. This research was focused on studying the effect of tin layer at the electrode tip for joining galvanized steel sheet. The main variable of this research is in the thickness of the intermetallic Cu 3 Sn layer. The result showed that the introduction of tin layer less than 1 µm in thickness on the electrode tip gives a comparable shear strength and nugget diameter distribution with the unplated electrode tip.

“…The study based on impact tensile testing to spot welded sheets, the effect of nucleus size on mechanical properties in electrical resistance spot welding of chromide micro alloyed steel sheets was investigated by Aslanlar (2006). Bouyousfi et al (2007) have studied the effect of process parameters (arc intensity, welding duration and applied load) on the mechanical characteristics of the weld joint of austenitic 304L stainless steel. The results showed that the applied load seems to be the control factor of the mechanical characteristics of weld joint compared to the welding duration and the current intensity.…”

Resistance spot welding (RSW) is a widely used joining process for fabricating sheet metal assemblies in automobile industry .In comparison with other welding processes the RSW is faster and easier for automation. This process involves electrical, thermal and mechanical interactions. Resistance spot welding primarily takes place by localized melting spot at the interface of the sheets followed by its quick solidification under sequential control of pressure watercooled electrode and flow of required electric current for certain duration. In this work the tensile tests were studied, the results obtained show that the type material, the overlap length, the angle of the rolling direction and the thickness of the sheet have an influence in resistance spot welding process.
