3. Introduction Materials application task I have chosen to analyse Mild Steel (grade) and aluminium(grade) to make my ______ out of. I will first look at the Chemical and Physical properties of each and then I will perform relevant test on each to test for suitability. These test will include welding, machining and cutting tests. In my conclusion I will indicate which material I have chosen and why.

6. Description I have conducted 3 test welding test MIG and Oxyacetylene, Cutting Test and a Machining test. The welding test is to see if it is possible to weld the material being tested with the equipment I have at school. The cutting test is to see how easily and accurately I can cut each material using the equipment I have at school. The machining test is to see how easily the material is to machine using the lathes we have at school.

7. Testing The purpose of testing each material is to establish which material has the most desirable characteristics and properties for my (insert project title). Testing Procedure Oxyacetylene Welding Test – I will try fusion welding two sample pieces of the material together, record the results and comment on suitability. MIG Welding Test – I will try to MIG weld two sample pieces of the material together, record the results and comment on suitability. Cutting Test – I will use a hacksaw, power hacksaw, and friction cut off saw to cut a 20mm round bar of each material, time how long it takes to cut and the quality of the finish record my results and comment on suitability of cutting. Machining – I will use a sample of the material and turn a diameter, centre drill and drill a hole on the lathe. I will record my results and comment on suitability for machining.
