4 Metal Fabrication Methods You Should Know By Now

metal fabricationThose in the metalworking industry know that good metal fabrication is one of the secrets to safer and more efficient metal structure production. There are various fabrication methods, and, depending on the specific work requirements, one might be more ideal than the others. Determining which method is appropriate, however, can be confusing,especially for those who do not know much just yet.

While there are professionals who can do the work for you, it still pays to understand how fabrication is done. This can help you concentrate on the quality and integrity of the metal structure you are working on. The following provides a brief glimpse into some of the most common metal fabrication methods:

Galvanizing

Rust is metal’s worst enemy; you need to make sure that the steel or iron used has adequate protection against rust and similar damages. Galvanization is the answer to this dilemma, according to industry experts like Service Steel, echoing sentiments by the American Institute of Steel Construction. The process involves application of protective zinc coating, which can be done via the electrodeposition and electrochemical processes.

Stress Relieving

Heavy machining operations induce stress in metal parts. This can create distortions and cracks, which compromises the quality of the metalworking output. This is the reason stress relieving is necessary on machined parts, especially the bigger ones. According to experts, you need to subject the particular metal parts to a temperature of about 165 degrees Fahrenheit. This removes about 90% of the internal stresses of the parts.

Abrasive Blasting

It is important to smoothen the surface of any metal parts for a more efficient operation. Industrialists typically do abrasive blasting. Apart from making the surface smooth, blasting also helps shape the part and removes surface contaminants. There are several kinds of abrasive blasting, which includes sand blasting and shotblasting.

Bending

Lastly, one of the most common fabrication methods you need to do is metal bending. This involves deforming a part on one of its axes and stressing it beyond yield strength. For good measure, you should work with seasoned metal benders to ensure the quality of your metal.

Metalworking is both a science and an art. You need to be precise when it comes to your method to create intricate designs. With a good grip of the various metalworking fabrication methods, you can experiment further and try producing complex metal structures.
