Welding vs. Metal Fabrication
Understanding the crucial differences between the holistic process and the joining technique.
The Core Difference
Metal Fabrication is the "Whole", while Welding is a "Part".
Metal Fabrication is the broad process of manufacturing metal goods—covering design, cutting, forming, and assembly.
Welding, on the other hand, is a specific technique within fabrication used to join two metal pieces using heat and pressure. While many fabrication projects involve welding, fabrication can exist without it (e.g., stamping or bending parts).
Key Takeaway:
- Fabrication = The entire journey (Design to Finish).
- Welding = The joining method (Heat & Pressure).
Fabrication Includes:
- • Cutting (Laser, Shearing)
- • Machining
- • Casting & Stamping
- • Bending & Forming
- • Welding
Welding Focuses On:
- • Fusion of Materials
- • Applying Heat/Pressure
- • Using Fillers
- • Creating Structural Bonds
- • Sealing Joints
The Metal Fabrication Journey
How a project moves from concept to final product.
Quote & Assess
Analyzing project details, quantity, and purpose. We evaluate in-house capabilities to ensure efficiency.
Prototyping
Creating a visualization model to refine the project. Essential for testing real-world demands before mass production.
Tooling
Shaping raw materials. Cutting metals to required sizes using laser cutting or shearing based on specifications.
Production (Welding)
Assembly and final joining. This is where welders play a crucial role in bonding components into the final product.
Common Welding Techniques
TIG Welding
Tungsten Inert Gas
Uses a non-consumable tungsten electrode. Produces precise, clean welds.
MIG Welding
Gas Metal Arc
Feeds a continuous wire electrode. Known for speed and efficiency in manufacturing.
Spot Welding
Resistance Welding
Uses pressure and electric current at specific points to join thin metals.
SMAW (Stick)
Shielded Metal Arc
Uses a consumable electrode with flux. Simple and effective for various conditions.
Tack Welding
Temporary Fix
Brief, low-heat welds to hold pieces in alignment before final welding.
Essential Tools
Fabricators focus on cutting/bending tools, while welders focus on heat/joining tools.
Safety First
Protecting vulnerable areas (eyes, hands, lungs) is mandatory during welding.
