Welding and types

Siva Pradeep Bolisetti

Welding is a process that joins metals by heating them to melting point and allowing them to merge together. There are two main types: plastic welding applies pressure and fusion welding fully melts the materials. Oxy-fuel welding uses a heated gas flame, such as oxy-acetylene, to melt the metals. It is inexpensive but has a lower temperature than other methods. The equipment includes welding torches, cylinders of gas, regulators to control pressure, and filler rods. Precise flame adjustment is required to protect the metal and achieve the necessary temperature.

ppt on Forging process

Forging is a metalworking process that involves shaping metal using localized compressive forces. It can be performed hot, warm, or cold. Forged parts range in weight from under a kilogram to 580 metric tons. Forging improves metals' strength and durability through grain refinement. There are several forging techniques including smithy forging (traditional hand forging), drop forging (using a hammer), press forging (applying continuous pressure), and roll forging (using opposing rolls). Forged parts generally require further processing to achieve their final shape. Common forgeable metals include carbon steels, aluminum, and titanium.

Friction welding

Friction welding

Preeti Joddabge

Friction welding is a solid state joining process that uses mechanical friction to fuse materials together without melting. There are several types of friction welding including spin welding, linear friction welding, friction surfacing, and friction stir welding. The process involves rotating or oscillating one material against another under pressure to generate heat and plasticize the surfaces. Friction welding produces high quality welds with small heat affected zones and without the need for filler metals. It has advantages over other welding methods like lower heat input and cost. However, it is generally limited to flat geometries and small parts.

Solid state welding

Abdullah Mansoor

Solid state welding involves joining materials without melting them using pressure and heat below their melting points. There are several types of solid state welding including forge welding, cold welding, friction welding, explosive welding, diffusion welding, and ultrasonic welding. Each type uses different techniques like pressure, vibration, or explosive force to join materials like steel, aluminum, and titanium without melting them. Solid state welding has advantages like avoiding defects from melting and ability to join dissimilar metals, but also has disadvantages like requiring expensive equipment or time-consuming processes.

Resistance welding

Resistance welding

Resistance welding

Resistance welding is described as an electric welding process where heat is generated by resistance of the workpieces to electric current in a circuit. Pressure is applied simultaneously with current to produce coalescence. Common resistance welding techniques include spot welding, seam welding, projection welding, and flash butt welding. Spot welding involves passing current through overlapping metal sheets held between electrodes to create nugget welds. Seam and projection welding can continuously weld moving sheets using arrays of electrodes.

GEARS HEAT TREATMENT

GEARS HEAT TREATMENT

GEARS HEAT TREATMENT

Natalino Fonseca

Heat treatment processes are used to change the properties of steel in gears. There are various types of heat treatments including annealing, normalizing, quenching, tempering, and surface hardening processes. For gears, common hardening processes include through hardening, case hardening using carburizing, nitriding or carbo-nitriding, and surface hardening using induction hardening or flame hardening. Case hardening produces a hard wear-resistant surface layer while keeping the core ductile, to increase pitting resistance without risk of tooth breakage. Surface hardening selectively hardens only parts of the gear like the tooth flanks, roots and tips.

Solid Solution

An alloy is a mixture of two or more elements that has metallic properties. A solid solution is formed when solute atoms are added to a host material (solvent) without changing the existing crystal structure. Hume-Rothery's rules state factors that influence solid solubility such as atomic radii difference of less than 15% and similar electronegativity. Phase diagrams graphically represent the phases present in a material system at different temperatures, pressures, and compositions.

Preeti Joddabge

Friction welding is a solid state joining process that uses mechanical friction to fuse materials together without melting. There are several types of friction welding including spin welding, linear friction welding, friction surfacing, and friction stir welding. The process involves rotating or oscillating one material against another under pressure to generate heat and plasticize the surfaces. Friction welding produces high quality welds with small heat affected zones and without the need for filler metals. It has advantages over other welding methods like lower heat input and cost. However, it is generally limited to flat geometries and small parts.

Abdullah Mansoor

Solid state welding involves joining materials without melting them using pressure and heat below their melting points. There are several types of solid state welding including forge welding, cold welding, friction welding, explosive welding, diffusion welding, and ultrasonic welding. Each type uses different techniques like pressure, vibration, or explosive force to join materials like steel, aluminum, and titanium without melting them. Solid state welding has advantages like avoiding defects from melting and ability to join dissimilar metals, but also has disadvantages like requiring expensive equipment or time-consuming processes.

Resistance welding

Resistance welding

Resistance welding

Resistance welding is described as an electric welding process where heat is generated by resistance of the workpieces to electric current in a circuit. Pressure is applied simultaneously with current to produce coalescence. Common resistance welding techniques include spot welding, seam welding, projection welding, and flash butt welding. Spot welding involves passing current through overlapping metal sheets held between electrodes to create nugget welds. Seam and projection welding can continuously weld moving sheets using arrays of electrodes.

GEARS HEAT TREATMENT

Natalino Fonseca

Heat treatment processes are used to change the properties of steel in gears. There are various types of heat treatments including annealing, normalizing, quenching, tempering, and surface hardening processes. For gears, common hardening processes include through hardening, case hardening using carburizing, nitriding or carbo-nitriding, and surface hardening using induction hardening or flame hardening. Case hardening produces a hard wear-resistant surface layer while keeping the core ductile, to increase pitting resistance without risk of tooth breakage. Surface hardening selectively hardens only parts of the gear like the tooth flanks, roots and tips.

Advanced control scheme of doubly fed induction generator for wind turbine us...

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Embedded machine learning-based road conditions and driving behavior monitoring

Embedded machine learning-based road conditions and driving behavior monitoring

Embedded machine learning-based road conditions and driving behavior monitoring

Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
