Mild Steel electrode ¢ 3.15 mm

 Equipment required:
A.C. Transformer with all welding accessories like Electrode holder, cables.
Tool Required:

  1. Steel rule 300mm 
  2. Scriber 150mm
  3. Flat file 300mm
  4. Try square 200mm
  5. Flat Tong 450mm 
  6. Chipping hammer 200mm
  7. Ball peen hammer 750mm 
  8. Wire brush
  9. Welding screen


Sequence of Operations:
1. Marking 
2. Filing 
3. Welding 
4. Finishing
Procedure:

  1. Take two Mild steel plates of size 80mm X 40mm X 6mm.
  2. Fix the work pieces one by one in bench vice and file the faces of work pieces using flat file as per dimensions.
  3. Then mark the pieces using steel rule and scriber as per drawing.
  4. Again fix the work pieces one by one in bench vice and file the pieces to get the required shape of the edge as per drawing.
  5. Select the appropriate welding fixture and hold the pieces as per drawing.
  6. At some selective places of the joint perform some weld spots for perfect alignment of the job.
  7. Start the welding from one end and proceed to another end.
  8. Like this continue the welding operation for one more time to get weld bead.
  9. Allow the welded joint for solidification.
  10. After cooling, chip off the slag from welded joint with the help of chipping hammer and clean the joint by wire brush.


Safety Precautions:

  1. Use welding screen leather apron and leather hand gloves while welding
  2. Use flat tong and hand gloves for handling of work pieces during and after welding.

Result:

 Single ‘V’ butt joint is prepared as per given dimensions.

TIN SMITHY & Sheet metal

TIN SMITHY Introduction : Many engineering and house articles such as boxes, cans, funnels, ducts etc. are made from a flat sheet of metal. The process being known as tin smithy. For this the development of the article is first drawn on the sheet metal, then cut and folded, to form the required shape of the article. Allowance should be given in the drawing stage for folding and bending. This allowance depends upon the radius of the bend and thickness of the sheet metal. Sheet Metal Materials : A variety of metals are used in a sheet metal shop such as galvanized Iron, black, Iron, tin, Stainless Steel, copper and Aluminium. Hand Tools : The common hand tools used in sheet metal work are steel, try square, Wire gauge, Scriber, Ball peen hammer, Nylon Mallet, Snips Divider, Stakes, Cutting plier and Soldering Iron. Here, the details of tools that are being equipped by our workshop purpose only are presented. Wire Gauge: The thickness of sheet is referred in numbers known ...

Isometric drawings for practice in AutoCAD

What is Isometric Drawing? Isometric drawing is a method of visually representing three-dimensional objects in two dimensions. It allows for a clear and comprehensive depiction of complex structures by keeping the scale consistent and eliminating distortion. Isometric drawings use a 30-degree angle from the horizontal in all three axes (X, Y, and Z), creating a pseudo-3D effect where the height, width, and depth are equally foreshortened. Creating Isometric Drawings in AutoCAD AutoCAD provides tools and settings that make creating isometric drawings straightforward. Here’s a step-by-step guide: Step 1: Set Up Isometric Snap/Grid 1. Enable Isometric Snap/Grid:    - Type `SNAP` in the command line and press `Enter`.    - Type `Style` and press `Enter`.    - Choose `Isometric` and press `Enter`. 2. Switch Between Isoplanes:    - Type `F5` or `CTRL+E` to toggle between the top, right, and left isoplanes. Step 2: Draw Isometric Circles and Arcs 1. Isom...

Fluid mechanics VIVA QUESTIONS and ANSWERS

1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter?
