#2 Welding – Fusion of Power
Welding stands unparalleled when it comes to enduring metal connections that can withstand the test of time and stress. It’s the cornerstone for numerous industries, creating solid and seamless bonds between metal parts.
Welding is favored for its capacity to merge materials without additional components, offering an intrinsically robust union. Welding is the unsung hero, from the iconic skyscrapers gracing our cityscapes to the vehicles we drive daily.
Here’s a brief overview of popular welding types:
- Arc Welding: An electric current forms an arc between the workpiece and an electrode, melting the metals at the welding point.
- MIG (Metaal Inert Gas) lassen: Uses a continuously feeding wire and shielding gas to join metals.
- TIG-lassen (wolfraam inert gas): Known for precision, it uses a tungsten electrode and inert gas, ideal for delicate work.
- Resistance Welding: Joins metals by passing current through the workpieces; often used in manufacturing.
- Oxy-Fuel Welding: Combines oxygen with a fuel gas to melt metals.

#3 Adhesive Bonding – Sticking Around
When aiming for a clean, seamless finish without visible fasteners, adhesive bonding is your go-to. This method is ideal for sheet metals that demand a smooth aesthetic and continuous surface.
Adhesive bonding is especially beneficial for joining metals with different properties or those sensitive to heat, as it eliminates the need for welding or riveting.
Types of adhesives for metal bonding include:
- Epoxy Resins: Offers high strength and durability, suitable for heavy-duty applications.
- Anaerobic Adhesives: Perfect for sealing threaded assemblies and filling gaps.
- Acrylic Adhesives: Fast setting and ideal for bonding dissimilar metals.
- Polyurethane Adhesives: Offers flexibility and strong bonds, especially on rough surfaces.
- Cyanoacrylate Adhesives: Known as superglues, they provide rapid bonding for quick fixes.
- Modified Silane Adhesives: Combines epoxies’ strength with the cyanoacrylates’ speed.
#4 Clinching – Pinch to Fix
Clinching is a go-to technique when achieving reliable, fast, and environmentally-friendly sheet metal assembly.
Sheet metal clinching is especially beneficial for applications that demand clean, smooth, and uninterrupted surfaces. Ideal for producing household appliances, electronic enclosures, and a myriad of other items, this method ensures stability without the fuss of traditional welding or fastening.
One can find various types of clinch joints, such as:
- Round Clinch Joints: Suitable for multiple layers and different material types.
- Oval Clinch Joints: Perfect for areas where higher static strengths are essential.
- Square Clinch Joints: Ideal for hard materials, offering an increased contact area.

#5 Laser Welding – Precision at its Finest
When you require an immaculate, pinpoint-accurate joint in your sheet metal projects, turn to laser welding. This high-tech method is perfect for metals that demand precision and a clean finish.
Laser welding is especially vital for projects that involve intricate designs or delicate parts. Its precision ensures minimal distortion and provides a seamless finish, making it indispensable for industries like electronics, aerospace, and medical devices.
Here’s a quick dive into some of its varied applications:
- Continuous Welds: Ideal for creating long, uninterrupted joints that demand high strength and durability.
- Pulse Welds: Perfect for small, delicate parts; it minimizes heat input and reduces distortion.
- Remote Welding: The laser can be directed from a distance for hard-to-reach areas, making assembly more flexible.
- Hybrid Welding: Combines the strengths of arc welding with laser welding for high-speed applications.
- Puntlassen: For joining parts at specific points, providing both flexibility and strength.
Filler Welds: Use laser welding with added filler material for increased joint thickness or specific material properties.
#6 Brazing – Joining Without Melting
Brazing is your go-to method for a robust, durable joint with a smooth, clean appearance. In metalwork, they prefer brazing because it effortlessly joins dissimilar metals and ensures an excellent finish every time.
Brazing utilizes a filler metal with a melting point lower than the joined metals. This ensures that the base metals remain structurally intact, thus providing a robust and aesthetically pleasing connection. This makes it perfect for applications demanding both strength and elegance.
Regarding specific applications, brazing shines in creating intricate jewelry pieces, advanced electronics, and even components in the aerospace industry. But it’s not just about the technical; the artistry achieved through brazing is unparalleled.

#7 Tab and Slot – Like Fitting Puzzle Pieces
The Tab and Slot method is an industry favorite regarding versatile and efficient sheet metal assembly techniques. The design, while straightforward, ensures precision and strength in every join, making it ideal for applications that demand reliability.
At its core, the Tab and Slot technique is about inserting a protruding ‘tab’ from one sheet of metal into a ‘slot’ of another. This interlocking method ensures alignment, positioning, and reduced warping during welding. It’s particularly advantageous for projects where consistent and repeated accuracy is paramount.
Among its various applications, Tab and Slot assembly shines in:
- Modular Furniture Design: Ensuring both aesthetic appeal and structural robustness.
- Mechanical Components: Where precision and alignment can make or break the functionality.
- Art Installations: Allowing artists to play with design without compromising stability.
#8 Hemming – Double Up for Strength
Hemming is a testament to precision and finesse in the vast realm of sheet metal assembly. This technique folds metal back onto itself, creating a seamless, clean, and finished edge. It’s not just about aesthetics; hemming enhances the strength and safety of the assembled parts.
Hemming is the go-to choice for professionals working on projects that demand a flawless finish, like custom metal furniture or luxury automotive bodies. This technique ensures edges are free from sharpness, making them safe to touch and more resilient to wear and tear.
When we delve into specifics, the hemming process has two main stages:
- First fold: This initial bend usually covers about 90 degrees of the metal.
- The Final Fold or Closing the Hem: After the initial bend, the metal is folded onto itself. This process essentially closes the ‘V’ or ‘U’ shape made during the preliminary angle. It forms a flattened edge, which is the final hem.
