This article analyzes the transient complex heat transfer and fluid flow in molten metal and arc plasma during the gas metal arc welding process. The model predicts the formation, growth, detachment, and transfer of droplets from the tip of a continuously fed electrode under the influences of several competing forces including gravity, electromagnetic force, arc pressure, plasma shear stress, a...

Welding is a technique used for joining metal parts usually during the application of heat. There are many types of welding, including an electric arc welding this means that process in which forms metal work piece and electrode, leads to heat metals cause them melt, connect with inert metallic gas (MIG). This study clarifies conclusion parameters such as travel speed, current wire feeding spee...

We compare ultrasonic welding (UW) and thermal bonding (TB) for the integration of embedded thin-film gold electrodes for electrochemical applications in injection molded (IM) microfluidic chips. The UW bonded chips showed a significantly superior electrochemical performance compared to the ones obtained using TB. Parameters such as metal thickness of electrodes, depth of electrode embedding, d...

In this paper, we develop a non-destructive inspection system for secondary battery welding. battery, when the insulation or separator of each electrode is damaged by an impact from outside depending on degree welding, internal short circuit occurs during charging and fires even if it does not ignite at that time. To detect this, AOI (Automatic Optical Inspection) developed compares target with...

Gas metal arc welding (GMAW) is a highly efficient and fast process for fabricating high quality weld. High quality welds are fabricated by proper selection of consumable includes gas and filler metals. The optimum flow rate of gas will ensure the proper quality of weld. In this project, a fluid flow behavior of different flow rate is modeled and the change quality will be studied. KeywordsHydr...

Shielded Metal Arc Welding is a liquid welding process (fusion welding) that produces heat from an electric arc between the electrode and workpiece. The depth of fusion formed determined by input, angle direction. research was conducted in Mechanical Engineering laboratory Padang Institute Technology. test material used low carbon steel 10 mm thick, 100 long wide. carried out on surface work as...
