The brake disc, also known as the rotor, is a key component in a vehicle's disc brake system. It is designed to be pressed against by brake pads during braking, which helps to slow down or stop the vehicle. Typically made from gray iron, a type of cast iron, the material provides excellent heat dissipation and durability.
Discs can come in various designs—some are solid, while others feature ventilation with fins or vanes that connect the two contact surfaces. This vented design is especially common in front brakes, where more heat is generated due to higher weight and power. The choice between solid and vented discs depends on the vehicle's performance and usage requirements.

2. Welding Electrodes - Welding electrodes are metal rods that are used to conduct electricity and create an arc. They are coated with a flux that helps to protect the weld from contamination and oxidation.
3. Welding Wire - Welding wire is used in the MIG welding process to feed the welding arc with a continuous supply of wire. It is available in different thicknesses and materials, such as stainless steel, aluminum, and mild steel.
4. Welding Helmets - Welding helmets are designed to protect the welder's eyes and face from the intense light and heat produced during welding. They come in different styles and designs, including auto-darkening helmets that automatically adjust to the brightness of the welding arc.
5. Welding Gloves - Welding gloves are used to protect the welder's hands from heat, sparks, and other hazards associated with welding. They are made from materials such as leather and Kevlar and come in different sizes and styles.
6. Welding Safety Glasses - Welding safety glasses are designed to protect the welder's eyes from the intense light and UV radiation produced during welding. They are available in different shades and styles.
7. Welding Filler Metals - Welding filler metals are used to add material to the weld joint to create a strong, durable bond. They come in different materials, such as stainless steel, aluminum, and bronze.
8. Welding Clamps - Welding clamps are used to hold the metal being welded in place during the welding process. They come in different sizes and styles, including C-clamps, locking pliers, and magnetic clamps.
9. Welding Flux - Welding flux is used to protect the weld from contamination and oxidation during the welding process. It is available in different types, including powder, paste, and liquid.
10. Welding Gas - Welding gas is used in the TIG and MIG welding processes to shield the welding arc from contamination and oxidation. It is available in different types, including argon, helium, and carbon dioxide.
