Design Considerations in Welding
Electron Beam Welding is a fusion welding process in which a beam of high-velocity electrons is applied to the material to be joined. The work-piece melt as the kinetic energy of the electrons is transformed into heat upon impact. The EBW process is well-positioned to provide industries with highest quality welds and machine designs that have proven to be adaptable to specific welding tasks and production environments.

Stick welding an ultimate guide for beginnersSophia Lorenn
Welding is a process to join two materials by softening with heat and applying pressure. It can be divided into different categories, including MIG, Arc, Gas, and TIG welding. Talking about stick welding, it is the most popular and common type of welding technique of arc welding.
EDM is a recent machining technique used to cut metals which can’t be cut with traditional methods. EDM works with materials of electrical conductivity.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. OUTLINE:
What is arc welding?
Can we join two different metal
parts?
Components of arc welding
When welding not allowed?
Importance of arc welding
Successful welding
Safety
3. What Is Electric Arc Welding?
Arc welding is the process by which two
metal parts are joined by melting the parts
at the points of contact.
4. Can We Join Two Different Metal Parts?
NO…………
Because Metal parts should be the same.
If not then the one part will melt slowly
rapidly than the other one.
5. Components of arc welding:
Work piece or base metal
Electrode
Electrode holder
Electrode lead(cable)
Welding table
Work peace Lead(cable)
Plug to power source
Input power lead(cable)
6.
7. When welding not allowed?
If temperature is below 25 degree c and
Humidity is above 70%, then welding will
be not allowed.
Cracks and rust will take place
8. Importance Of Welding?
Welding is using in different ways….
Water supply(Pipe lines)
Traveling(cars, buses etc)
Electricity supply(Towers)
Defence(Tanks etc)
9. Successful welding?
Successful welding depends on the
following factors:
Correct welding current:
Correct current selection for a
particular job is an important factor in
arc welding.
Electrode Size (mm)
Current Range (Amp)
2.5
65 to 90
3.2
110 to 130
4.0
140 to 165
5.0
170 to 260
10. Electrodes Size:
The size of the electrode generally
depends on the thickness of the section
being welded, and the thicker the section
the larger the electrode required.
Average Thickness of Plate Maximum Recommended
or
Electrode Diameter
Section
1.5 to 2.0 mm
2.5 mm
2.0 to 5.0 mm
3.2 mm
5.0 to 8.0 mm
4.0 mm
11. Correct Travel Speed:
The electrode should be moved along in
the direction of the joint being welded.
Electrode Size
(mm)
Electrode
Length (mm)
Run Length
(mm)
4.0
350
175(min) and
300(max)
3.2
350
125(min) and
225(max)
2.5
350
100(min) and
225(max)
12. Correct preparation of work to
be welded:
Correct equipment
Correct method
Correct angle of electrode to
work:
Angle should not be 90
13. Arc Welding Safety:
Some potential hazards are given below.
Arc rays
Noise
Electric shock
Fumes and gases
Protective clothes
14. Arc rays:
Welding arc is brighter than the sun, so it
can harm your eye site
It can even burn your eyes and skin
Glasses can save your eye site
15. Noise:
Loud noise can harm your hearing capability.
Noise can be controlled by using ear plugs
and air muffs.
16. Electric shock:
Electric shock can even kill you, so dont
touch any live electric parts
Must insulate yourself by protective clothes
17. Fumes and gases:
Fumes and gases can harm you.
Ventilation must be there in the welding
room, so that fumes and gases can exhaust
outside
Keep your head out of the range of
dangerous gases
