3 Nifty Facts about the Metalworking Process Used to Manufacture your Car

Ping! Can’t you hear the ring of the hammer on the anvil? Metalworking sure has taken many different forms throughout its long history. It’s evolved as technologies have developed. Metalworking processes become more refined and adapt as today’s machinery changes shape.

 

But at its core, the basic metalworking principles remain the same. And while there aren’t as many blacksmiths swinging hammers today as there once were, there sure is a lot to know about metalworking! So read on to learn a few facts about some of these types of metalworking.

 

1. Casting

Casting metal is one of the oldest forms of metalworking. The oldest known metal casting in existence is dated to 3200 BC!

 

In this process, raw metal is heated to the point of melting. That’s 1370 degrees Fahrenheit for steel, the primary metal used to make up your car. When the metal is melted, it is poured into a mold and solidifies as it cools into a specific form. Working the metal into the desired form from its molten state eliminates the need for other types of metalworking processes and assembly of parts.

 

Casting is the most flexible form of metalworking and is ideal for a wide range of shape applications.

 

2. Metal Stamping

Stamping is used to give a sheet of metal a raised area without puncturing. This process can be used for lettering, or certain details or raised portions on the hood of a car. To get a better understanding of metal stamping’s potential, look to the coin. The images pressed into the front and back of coins are created using a stamping press.

 

Metal stamping is thought to date back to medieval times, with the blacksmith’s hammer creating the force needed to stamp an image into a sheet of metal.

 

Today’s industrial stamp press machines can outswing any blacksmith, often producing thousands of stamped pieces a day. With that type of workload, stamp press repairs are critical to keeping these machines going in order to meet the demands of manufacturing.

 

3. Welding

Metal welding is often the first area of metal fabrication that metal workers pursue. Simply put, welding is the joining together of two or more pieces of metal parts. When all of the individual parts of your car are ready for assembly, they are then welded together to form the frame. The frame is what gives your car structural integrity, so welding has to be very strong in order to hold up to the forces exerted on the joints.

 

Welding works by the use of heat to melt the two pieces to be joined at their intended seam. It also will employ the use of filler material, or welding rod, which is also melted. The high heat needed for this process comes from an electrical arc and as it all cools down, the pieces harden together and a very strong bond is formed.
