Being a metal fabricator is more than just having the tools to do it. It requires a variety of hands-on skills, technical know how in various fields of the industry.
The core skills required to be a metal fabricator include.
Knowing how to read drawings
Fabricators need to know how to read drawings provided by engineers and architects and transform them into steel structures.
Need to understand symbols, dimensions, tolerances, weld sections and know how to find where problems may occur.
Measuring
When installing structural steel it needs to be pretty much perfect in measurement. Even a millimeter off can push the whole assembly out of place making it difficult to place bolts , etc.
So you need to know how to use rulers, measuring tapes, calipers, squares and gauges.
Metal Cutting
Knowing how to cut metal helps in making your time more efficient and saves material from waste.
Need to know how to use angle grinders, band saws, plasma cutters and oxy torches. You also need to understand when to use each method.
Welding
Welding is one of the most critical steps that holds the structural steel together into whatever structure that needs to be created.
You need to be able to weld in at least one welding type but its best to know all.
You need to know how to prep the joins, apply filler-metal and know how to clean the weld after it is complete.
Welding types include: MIG, TIG or Stick
Finishing up
When the welds are finished they may need to be ground to meet the professional look and clearance needs.
Parts need to be checked if they fit perfectly before being tack welded top avoid mis-alignment.
Knowledge of different metals
There are different types of steels, alloys and aluminium that need to be known about and how they react to different circumstances.
There are also different grades that need to be known about for example: mild steel and high-tensile.
Need to know appropriate heat and welding treatments also to know which metals can be welded together.
Problem Solving
Every job is different and you can run into different problems. You need to know how to fix or work around these.
Safety
Operating tools and metals can be dangerous so certain guidelines and protection need to be followed.
Need to understand basic Math & Geometry
You need to know how to calculate angles, lengths, bend allowances, etc.. How to cut lengths for mitered corners and converting units.
Detail
All jobs need to have a nice finish and look presentable. Customers will notice when welds arent clean or if the finishes are smooth.
All joints need to be checked and sharp edges need to be deburred.
