What are the 3 stages of metal?
The Metal Age is divided into three stages: the Copper Age, the Bronze Age and the Iron Age.
What is tempering of metal?
tempering, in metallurgy, process of improving the characteristics of a metal, especially steel, by heating it to a high temperature, though below the melting point, then cooling it, usually in air. The process has the effect of toughening by lessening brittleness and reducing internal stresses.
What is a fabrication diagram?
The Fabrication Diagram is a diagram that facilitates the build of a prototype. It contains a visual representation of all fabrication steps and parts. The visual representation allows the fabrication team to understand which steps may be taken in parallel and which steps are done sequentially.
What mineral makes steel stronger?
Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy it decreases the brittleness of steel and imparts strength.

What is the hardest metal to weld?
Aluminum is a nightmare for welders. It is considered the most difficult metal to weld, because, in its ore or alloy form, it has various physical and chemical properties that need to be understood in detail before working on it.
Is normalizing and tempering the same?
Tempering treatment means that the steel after quenching hardening or normalization treatment is cooled down at a certain rate after being immersed for a period of time below the critical temperature.
What is a prototype design?
A prototype is a product built to test ideas and changes until it resembles the final product. You can mock-up every feature and interaction in your prototype as in your fully developed product, check if your idea works, and verify the overall user-experience (UX) strategy.
What is the first stage in metal work fabrication?
Planning & Designing. The first step, no matter what type of metal fabrication project you’re working on, is planning and design. This involves working with a metal fabricator to develop a strategic plan for your project, along with the design of the specific parts.
