In this study, the researchers designed and constructed a prototype device Automatic Streetlight Controller with anti-theft alarm using a Light-dependent resistor (LDR) and Photodiode – Infrared LED tandem. This study was conducted to assess the qualitative description, functionality, and level of acceptability regarding the constructed Automatic Streetlight Controller with Anti-theft device in terms of its performance as to device and simulator/trainer, the convenience of use, safety, assembly of parts, and cost. A mixed research design was used that includes both qualitative and quantitative research design. The qualitative description of the device was presented in narrative form and assessed using a focused-group discussion. Quantitative research design is done using quasi-experimental in testing the functionality, trials were made to assess its functionality and descriptive survey method was used to assess the level of acceptability. Probability sampling was also used thru the lottery method to get the two (2) selected groups of respondents: the 3rd year BSIT- Electricity block B students and community barangay officials of Calunasan, Calape, Bohol. T-test was used to test its significance using the 0.05α. Results have shown that on testing the device has 100% good performance and is rated as it functions well. The acceptability level was rated “very high” which means highly acceptable by both respondents. Therefore, the device can be used if implanted in existing street lights or newly built ones to improve the condition of our street lights to properly illuminate the streets for an improved security system. 01 30 2022 87 91 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.D6613.0110522 https://www.ijrte.org/portfolio-item/d66131110421/ Department of Mechanical Engineering, Annapoorana Engineering College, Salem (Tamil Nadu), India.

Tungsten inert gas welding (TIG) is more stable and allows for more precise control than most other arc welding processes. TIG welding is desired in the aerospace sector when thin parts have been welded with accuracy. However, when welding thick sections, autogenous TIG welding is not commonly recommended due to the limited depth of penetration required. It is in effective for joining the thick parts in a particular pass. Welding with activated flux tungsten inert gas (A-TIG) enhances weld penetration by four times in a single pass. This process will improve penetration depth, depth/width ratio and also, minimize angular distortion and residual stresses. A-TIG is the topic of investigation among researchers due to its deep penetration capacity. Properties of A-TIG welding in diverse materials was investigated in this study which also discusses the mechanisms, varied forces like lorentz force, buoyancy force, shear stress prompted by plasma jet, shear stress prompted by surface tension gradient, reverse marangoni force and aerodynamic drag force induced in the weld pool. The impact of activated fluxes on various materials of A-TIG weld was also investigated in this study. Recent advancements in TIG welding methods were also explored. According to the findings, A-TIG welding improves weld penetration significantly, but there is a lot of slug on the weld surface. This constraint can be addressed by using new versions of the A-TIG welding progression, such as flux bounded and the flux zone. 01 30 2022 92 105 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.E6770.0110522 https://www.ijrte.org/portfolio-item/e67700110522/
