Metal brazing and soldering - processes
Brazing is a metal joining process where a filler metal above 450°C is melted and drawn into the gap between close-fitting metal parts by capillary action. The filler metal interacts with a thin layer of the base metal to form a sealed joint that is generally stronger than the individual filler metals due to metallurgical bonding. Soldering is similar but uses a filler metal with a lower melting point below 400°C, making it suitable for joining thin parts but resulting in weaker joints. Both processes allow dissimilar metals to be joined but have limitations such as appearance differences, toxicity of fluxes, and maximum operating temperatures.
Welding
Welding is a process that joins materials by causing fusion and filling the joint with a filler material. There are several advantages to welding including lighter structures, maximum strength in joints, easy alterations, pleasing appearance, and strength equal to the parent material. Spot welding uses two electrodes to locally fuse materials and is commonly used in automotive and aircraft industries to join sheet metal. MIG welding uses an inert gas shield to prevent contamination and is often used for carbon/alloy steels, stainless steel, aluminum and other metals due to its high welding speed and economy. Common welding defects include lack of penetration, undercut, slag inclusion, porosity, cracks, spatter, and distortion.

welding process.pptx
Welding is a process for joining metals using heat. Arc welding uses an electric arc to generate heat and melt the metals, which fuse together upon solidification. Flux shielded metal arc welding (SMAW) uses a consumable electrode coated in flux that decomposes to protect the weld area from contamination. When an arc is struck between the electrode and workpiece, the electrode melts and deposits filler metal into the weld joint. SMAW is versatile and can weld many metals, but uses consumable electrodes and produces slag, so defects can occur during restarting welds.

Forming can also improve properties like strength and sound absorption. Porous metals are also able to take on more complicated shapes than solid metals. Overall, forming processes can enhance properties but also reduce porosity, and porous metals may have applications where solid metals cannot be used.
FCAW.ppt
Flux-cored arc welding (FCAW) is a semi-automatic welding process that uses a continuously-fed consumable tubular electrode containing a flux along with an arc to produce the weld. Shielding is provided either by gases from the flux inside the electrode or an externally supplied gas. FCAW allows for high welding speeds, is portable, and overcomes restrictions of SMAW. It can be used for both self-shielding without gas or gas-shielding with an external supply, with different advantages for each type.

With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

- 2. Classification of Welding Processes
- 3. Definition of Welding:- • Welding is a process of joining similar and dissimilar metals or other material by application of heat with or without application of pressure and addition of filler material. • It is used as permanent joints. • Weldability-The weldability has been defined as the capacity of being welded into inseparable joints having specified properties such as definite weld strength proper structure
- 4. The weldability of any metal depends on five five five five major factors-- • melting point • thermal conductivity • thermal expansion • surface condition • change in microstructure.
- 5. FLUX FLUX FLUX FLUX- - - - • Flux is a cleaning agent used to avoid the contamination of welded joint by impurities like oxides, by oxygen combined with metal during welding. • Flux dissolve oxide,trapped gases and slag(impurities) from base metal
- 6. TYPES OF JOINTS IN WELDING: TYPES OF JOINTS IN WELDING: TYPES OF JOINTS IN WELDING: TYPES OF JOINTS IN WELDING:- - - -
- 7. Another Classification of Welding Another Classification of Welding Another Classification of Welding Another Classification of Welding: : : :- - - -
- 8. Autogenous welding Autogenous welding Autogenous welding Autogenous welding: : : :- - - - • Autogenous welding is one way of performing fusion welding without the application of external filler material. • •Solid state welding processes are usually autogenous as they don’t use any filler during welding • Plasma Arc Welding (PAW), Laser Beam Welding (LBW), Electron Beam Welding (EBW), etc. are mostly autogenous.
- 9. Advantages of autogenous welding Advantages of autogenous welding Advantages of autogenous welding Advantages of autogenous welding: : : :- - - - • Fusion welding of thin sheets is possible only in autogenous way. • No extra cost for filler material. •Weld appearance is good. •Processes can be easily automated. •No post-grinding is required to remove reinforced parts. Disadvantages of autogenous welding • Strength of the joint is not good—it is less than the strength of base plates.
- 10. • These joints are crack-sensitive due to lack of molten metal supply during solidification. • Only butt joint is possible and that too maintaining no root gap between parent parts. Heterogeneous welding:- • Heterogeneous welding is one way of performing fusion welding with the application of external filler whose metallurgical composition is substantially different from that of the base metals.
- 11. • So if filler material is applied during joining and the metallurgical composition of filler is different from that of the base metal then it is termed as heterogeneous welding. • Brazing and soldering are common examples of heterogeneous joining. Disadvantages of heterogeneous welding:- • Filler material is usually costlier and it also requires proper maintenance. • Application of excess filer material causes high reinforcement on weld bead, which are required to remove after welding by grinding.
- 12. • Appearance of weld bead is not good. Advantages of heterogeneous welding:- • Thick plates can be welded efficiently with proper edge preparation. • Strength of the joint is excellent—better than autogenous welding. homogeneous welding:-
- 13. • The process of joining similar metals with the help of a filler rod of the same metal is known as homogeneous welding. • Examples of homogeneous welding are Gas Metal Arc Welding, Electroslag Welding, Submerged Arc Welding.
- 14. Advantages of homogeneous welding Advantages of homogeneous welding Advantages of homogeneous welding Advantages of homogeneous welding: : : :- - - - • Thick plates can be welded efficiently with proper edge preparation. • Strength of the joint is excellent—better than autogenous welding. • Due to sufficient supply of molten metal, tendency of crack formation during solidification reduces. •Disadvantages of homogeneous welding:-
- 15. •Not possible for joining of very thin sheets (causes distortion). • Excess filler material causes reinforcement on weld bead, which are required to remove after welding by grinding (mandatory post-processing). • Appearance of weld bead is not good. • Presence of filler sometime causes sputter. • Extra cost for filler material and also its maintenance.
