WORKSHOP SAFETY
INTRODUCTION
The most important factor in establishing safe working conditions in the workshop is YOU - the student.
8
The Education Department provides rooms in which you can work safely, and machines with special safety guards.
Your teachers will instruct you in the correct use of tools and machines, and lay down rules for your behaviour in the room.
Rules and instructions, and safety guards, however, will not prevent accidents if YOU are careless or irresponsible.
Accidents do no happen - they are caused, and it has been proved that in nearly all cases the cause is not machines or tools, but people.

RESISTANCE WELDING
In resistance welding, the joint is produced by heat which is developed by resistance to an electric current, combined with pressure applied to the meeting surfaces. This process combines both electrical and mechanical energy to produce the weld.
Using the Spot Welder
1) Check that the point tips are flat and close to 3 mm in diameter.
2) Adjust the clamping pressure so that a slight resistance to the full locking of the clamp lever is felt.
3) Position the spot welder squarely to the work so the point tip sits squarely on the work.
4) Depress the switch for as long as is necessary for the metal in the weld area to become red hot. (Approximately one second). 5) Do not exceed the capacity of the welder. The maximum rate of welding is approximately 5 - 6 welds per minute.
List some welding faults which may occur during resistance welding.

PULLEYS
A pulley can be considered as a wheel fixed to a shaft and is used in conjunction with a belt. Belts and pulleys transmit rotary motion and power from one shaft to another, usually placed at a reasonable distance apart.The speed of the driven shaft can be changed by changing the ratio of the pulley diameters and the direction of rotation can be changed by using a different belt arrangement.The diagrams below illustrate changes in speed and direction, where pulley A is the Driver and Pulley B is the driven.
Describe what is happening to pulley B in each diagram.

Types of Pulleys.
Belts and pulleys are used in mechanical applications where a slight amount of slipping can be tolerated. In some situations slipping may even be a necessary part of the mechanical operation. The main types of pulleys are listed below and illustrated in the diagram. Match the name of the pulley with its illustration.

INTRODUCTION:
A Drill Gauge is a useful hand tool that allows an unknown drill size to be checked against a gauge to determine its size as well as its angle. A well-made gauge can give many years of accurate service.
REQUIREMENTS:
You are required to make the drill gauge, to an acceptable standard (ie the tool should be accurate as per the tolerances and useable). The steps, in their correct order, that are required are listed below:
1. From the drawing supplied the student is to compile a procedure sheet for the making of the drill gauge. This is to include; material needed, all processes (in order) to be carried out, tools and machinery, as well as an estimated time on how long each step takes. The procedure sheet is to be written out in a legible manner, marked by your teacher prior to material being handed out.
2. Make the drill gauge as per the information provided.3. Once the task has been completed draw your gauge on the sheet provided.4. Complete remaining theory.
Break each task into small steps. This will make it easier for you to set out your procedure prior to you commencing work. It will also assist you in identifying potential problems before they occur. This is important in engineering as mistakes can often be costly in time, material and money. Once your procedure has been checked follow it in production. If you have any questions or doubts ASK. The purpose of this assessment piece is to:
Develop your planning skills Use workshop machines for basic operations Build on your hand tool skills Develop your engineering communication skills through drawing
