Mesh fencing offers durability, visibility, and versatility for property lines, animal enclosures, and construction sites. However, ensuring a solid, lasting bond between the mesh and posts depends heavily on selecting the right welding method and preparing the materials correctly. This article explores the pros and cons of popular welding techniques for mesh fencing and how tools like those from Tomahawk can improve your setup and workflow.
MIG vs. Stick Welding: What Works Best?
When welding mesh fence panels to metal posts, the two most commonly used techniques are MIG (Metal Inert Gas) welding and stick (SMAW) welding. MIG welding is generally easier for beginners and works well on thinner materials. Its continuous wire feed provides a cleaner weld and faster workflow, especially in controlled conditions. However, MIG welding requires shielding gas and may struggle outdoors where wind can disrupt gas coverage.
Stick welding, on the other hand, is more forgiving on dirty or rusty surfaces and better suited for outdoor environments. It penetrates deeper into thicker metals, making it ideal for structural posts, but it can be more challenging for precise welds on thinner mesh.
Your choice depends on the job conditions. If you're working in an open area exposed to wind and humidity, stick welding offers more consistency. For indoor or controlled projects requiring neater welds, MIG is typically preferred.
Preparing for a Strong Bond
Regardless of technique, surface preparation is critical. Rust, paint, and grime must be removed from both the mesh panel and post to ensure a strong bond. This is where the Tomahawk Electric Demolition Jackhammer (35 lb, 1500W) can prove useful. While traditionally used for breaking concrete or asphalt, this heavy-duty tool is also effective for removing metal anchors or clearing mounting surfaces before welding.
A clean, prepped surface reduces spatter, improves weld penetration, and minimizes porosity in the weld—key to ensuring your mesh fence holds up over time.
Final Setup and Technique Tips
Clamp mesh panels tightly to posts before welding to avoid misalignment. Tack weld in several places before running full beads, allowing you to make adjustments. Use short welding intervals to prevent heat distortion on thin mesh, and always inspect the weld for full penetration without burn-through.
Once the welding is complete, a light sanding followed by rust-resistant primer or paint will protect the joint and extend the life of your fence.
In summary, whether you choose MIG or stick welding, the key to a successful mesh fence installation lies in preparation, precision, and the use of reliable tools. By combining proper technique with quality equipment like Tomahawk’s demolition jackhammer for prep, your fence will stand strong for years to come.
