A Welder Fabricator is some one that welds as well as assemble parts to make machinery.
Corrosion is occurs when a metal becomes wet or damp. A current flows through this, making the unmoving particles throught the steel to the more reactive parts on the surface. These are called anodes. The current returns from the more reactive parts, through it, and then back to the the more still parts. Where the current leaves the anode, rust forms. Wet corrosion happens when a metal or other material is wet or damp- (or can be caused through the mositure in the air) Dry corrosion is similar, however the difference is that it forms through the presence of gasses in the air
A common three-letter metal is "Tin," which has the chemical symbol Sn. It is a malleable and ductile metal often used in coatings for other metals to prevent corrosion, as well as in alloys like bronze. Tin is known for its resistance to corrosion and is also used in solder for joining metal parts.
A plater welder primarily focuses on welding large plates of metal, often used in the construction of ships, heavy machinery, and structural components. In contrast, a fabricator welder works with a variety of materials and is involved in the complete fabrication process, including cutting, shaping, and assembling metal parts into finished products. While both roles require welding skills, the plater welder's work is more specialized towards heavy plate work, whereas the fabricator welder has a broader scope that includes design and assembly.

Aluminum parts of an airplane are often painted with a green zinc chromate primer to protect the metal from corrosion.
This is a phenomenon which can occur when a metal is in contact with an environment that contains different concentrations of electrochemically active constituents at different points on the surface of the metal and thereby maintains differences of electrical potential on different parts of the surface of the metal.
Volatile corrosion inhibitors (VCI) are a type of corrosion inhibitor used to protect ferrous materials against corrosion where it is impractical to apply surface treatments. They slowly release compounds within a sealed airspace that actively prevent surface corrosion. A typical application is to protect stored tools or parts inside bags, boxes or cupboards, one advantage of VCIs being that if the container is opened and reclosed, levels of inhibitor will recover.
tilt the handle(gently so as not to do any damage on any parts) to be able to expose the connection of the handle to the door panel. you will see a clip that locks the plastic handle to a metal shafting. using a metal tool (a pusher, or a flat screw driver), gently remove the clip and then pull the handle.
The metal part itself would be a conductor in theory but the handle would be an insulator as it is usually rubber or plastic.
The grease is there to lessen friction between two metal parts. Without grease the moving parts would heat up due to the friction.
