Fabrication Processes
Cards in this deck (9)
- 1What is Welding?Permanently joining two pieces of metal together.
- 2What is MIG Welding?Ues electricity to generate the heat required to weld materials.
METAL INERT GAS - 3Advantages of MIG Welding?- Suitable for large scale production
- Varying thickness of materials can be joined.
- Reduced cost because the production of neat and clean metal deposits on the workpieces means thate is no need for extra cleaning. - 4What is Oxy-acetylene?Uses gas to weld metal. A flame is produced using oxygen and acetylene.
No pressure on product - the heat controls the welding of the parts. - 5Advantages of Oxy-acetylene- Ease of controlling the low and high temperatures needed for welding
- Inexpensive used by schools and colleges for this reason - 6What is Spot Welding?A type of electrical resistance welding used to join sheet material together. A transformer is used with 2 electrodes. When they trap the sheet material they generate heat to fuse the two together.
- 7Advantages of Spot Welding?- The process is free from fumes or spatter
- Requires little or no maintenance
- Cost effective - 8What is Shearing?A process used to cut straight lines on a range of materials from sheet metal to angle bar stock.
- 9Shearing what happens?An upper and a lower blade are forced past each other, one blade is stationary. Materials sheard include aluminium, brass, mild steel and stainless steel.
