Metal Fabricating: What You Need To Know

Metal fabrication is the process of creating artifacts or structures by designing, cutting, joining, and assembling raw metal materials.

This process seeks to add value by sticking to accurate engineering drawings so that the final product is attractive, meets the required standards, and is durable. Metal production is an art that is based heavily on technical principles. You can also get the best metal engineering services by clicking at:

Metal production process

Step 1: Design

There are well-defined standards (British standards, Eurocodes, etc.) and laws governing the design of all technical devices and structures. This standard is based on the use of raw materials available in a particular area as well as environmental conditions.

Step 2: Marking Out

In small-scale metal production, marking is carried out directly from the design drawing, using square edges or straight lines on the sheet metal as a reference point. However, in mass production, stencils made of wood, metal, or special paper are used, depending on the quantity and type of product.

Step 3: cutting

Sheet metal cutting can be done by cutting or thermal cutting. Thermal cutting is carried out using oxyacetylene or oxy propane gas. Propane is cheaper but requires a special cutting nozzle.

This process begins by heating the carbon steel to 8500 C, which creates an exothermic reaction which further increases the temperature. The principle of fast oxidation applies to thermal cutting.

Step 4: education

Sheet metal bending is carried out with the help of a folding machine, which includes 3 basic steps. First, the material is tightened firmly, then the lower folding rod is pulled out to make the desired bend, and finally, the material is carefully removed from the machine.

Step 5: Join

Welding is the most common method of joining. For metal manufacturing, a gas shielded metal arc is the most preferred method. The burner is connected to the positive pole and its energy source is direct current.

Step 6: Review

After the workpiece is fully assembled, it is checked for dimensional accuracy, alignment, and straightness to ensure that it is within acceptable limits.
