METAL FABRICATION

Metal fabrication refers to the process of creating metal structures, components, or products by cutting, bending, assembling, and finishing metal materials. It is a fundamental process used across various industries, including construction, automotive, aerospace, and manufacturing.

KEY METAL FABRICATION PROCESSES

Cutting:

• Techniques to cut metal into desired shapes or sizes:
• Shearing: Cutting straight lines using a shear machine.
• Laser Cutting: High-precision cuts using a laser beam.
• Plasma Cutting: Uses plasma (ionized gas) for fast, precise cuts on thick metals.
• Waterjet Cutting: High-pressure water mixed with abrasives for precise, heat-free cutting.
• Sawing: Bandsaws or circular saws for cutting.

Bending:

• Forming metal into shapes by applying force:
•  Press Braking: Uses a press brake machine to bend sheet metal.
• Roll Bending: Rolling metal sheets into curved shapes, like cylinders.
• Manual Bending: Hand tools for smaller or simple bends.

Welding:

• Joining two or more metal parts together:
• MIG Welding: Uses a continuous wire electrode and shielding gas.
• TIG Welding: Precision welding using a tungsten electrode.
• Arc Welding: Uses an electric arc to melt and join metals.
• Spot Welding: Fuses metal at specific points, common in thin sheets.

Machining:

• Removing material to achieve specific shapes or dimensions:
• Milling: Removes material using rotating cutting tools.
• Turning: Shapes metal on a lathe.
• Drilling: Creates holes.
• Grinding: Smooths surfaces and achieves tight tolerances.

Assembling:

• Joining parts through welding, fastening, or riveting.

Finishing:

• Enhances the appearance, functionality, or durability of metal:
• Polishing: Smooths the surface for aesthetics.
• Painting/Powder Coating: Adds color and protection.
• Plating: Adds a protective or decorative layer (e.g., chrome or zinc).
• Anodizing: Increases corrosion resistance, especially for aluminum.
• Deburring: Removes sharp edges or burrs from cut or machined parts.

MATERIALS USED IN METAL FABRICATION

Steel:

• Types: Carbon steel, stainless steel, alloy steel.
• Applications: Construction, automotive, tools, and machinery.

Aluminum:

• Lightweight, corrosion-resistant, and easy to work with.
• Applications: Aerospace, automotive, and consumer products.

Copper:

• Excellent electrical and thermal conductivity.
• Applications: Electrical components and plumbing.

Brass:

• Corrosion-resistant and aesthetically appealing.
