Welding Process

By Rahmat Azis Nabawi According to the definition of the Deutsche Industrie Normen (DIN) as cited by Harsono and Toshie (2000), welding is defined as "a metallurgical bond produced between metallic materials in the molten or liquid state." In other words, welding is a metal joining process in which the base materials are locally heated until they melt, allowing a permanent metallurgical bond to be formed after solidification (Harsono & Toshie, 2000). Before welding operations are carried out, a comprehensive welding procedure should be prepared. The procedure includes selecting the appropriate welding process, determining the required equipment, and establishing production quality requirements. The quality of a welded joint depends not only on the welding operation itself but also on the preparation performed before welding begins (Cary & Helzer, 2005). Proper welding preparation generally consists of selecting the appropriate welding process, preparing...

Cutting Process

By Rahmat Azis Nabawi The cutting process is one of the most critical stages in steel fabrication, during which steel profiles and steel plates are cut according to the cutting lines established during the marking process. This operation plays a significant role in ensuring the dimensional accuracy of fabricated components, which directly influences the quality, fit, and structural performance of the final product. Various cutting methods are employed in steel fabrication, each offering specific advantages depending on the material type, plate thickness, production requirements, and desired cutting precision. Selecting an appropriate cutting technique is essential for achieving high-quality fabrication results while improving productivity, minimizing material waste, and ensuring dimensional accuracy. The most commonly used cutting methods include Hydraulic Shearing , Oxy-Fuel Flame Cutting , and Computer Numerical Control (CNC) Cutting . Each method has unique operating p...

CFD-Based Taguchi Optimization of Impeller Geometry to Improve Centrifugal Fan Efficiency: A Review of an Integrated Design Optimization Framework

Industrial centrifugal fans are widely used in ventilation, HVAC, and manufacturing systems, where energy efficiency directly influences operational costs and environmental sustainability. Because fan performance is strongly governed by impeller geometry , optimizing design parameters has become an important engineering challenge. Conventional optimization techniques often require numerous Computational Fluid Dynamics (CFD) simulations, resulting in considerable computational expense. The reviewed study proposes an integrated optimization framework that combines CFD simulations with the Taguchi design-of-experiments method to identify efficient impeller configurations while minimizing computational effort. By investigating the effects of inlet blade angle , outlet blade angle , blade number , and flow rate , the research demonstrates how statistical optimization can be effectively integrated with numerical simulation to improve centrifugal fan efficiency and support practical engineer...
