Weld on 3 and 4 are specialized type of adhesives that are used in the manufacturing process of metalwork. They are liquid adhesives that can be applied by brush or roller to the surface of the metal being welded. The product is then allowed to dry and set before any welding can take place
Both brands offer high-quality adhesives that are easy to use and require little to no prep work before application. Both brands also provide excellent bonding strength when properly applied to surfaces such as glass, plastic, metal, and more!
What is Weld-on 3?
Water-thin, fast-drying acrylic Weld-On 3 can be used as a metal filler. Weld-On 3 bonds metals and insulates from electric currents.
Exhaust systems and vehicle frames are often repaired with it. It repairs sheet metal like car roofs and fenders.
Applying adhesive by brush or spray gun and letting it dry for 24 hours before joining.
Weld-On 3 cures rapidly at room temperature and can be used for numerous repairs. Repairing plastic, rubber, vinyl, and some metals is easy using Weld-On 3. It’s also great for gluing fresh to old or broken parts.
What does Weld-On 3 cure into?
The curing reaction of Weld-On 3 will result in a tough yet flexible joint between two materials with very little shrinkage or distortion. The final product has excellent resistance to impact and abrasion as well as weathering, including UV exposure.
What is Weld-On 3 Used For?
Weld-On 3 can be used in a variety of applications:
Welding – Weld-On 3 can be used as a primer for all types of welding, including arc welding and gas welding. It provides an excellent bond between metal surfaces and improves their corrosion resistance.
Adhesive – Weld-On 3 can be used to bond various materials together and also provides an extremely strong bond between metal surfaces and other materials such as wood and glass.
Protective Coating – Weld-On 3 can be used as a protective coating against rusting or corrosion on items such as lawnmowers, bicycles, etc
What is Weld on 4?
Water-thin acrylic glue Weld-On 4 repairs metal surfaces. It is liquid and can be applied with a brush or stick dipped in it. Only an expert should spray it on.
Weld-4 comes in low and high temperatures. Low-temperature welding is used for aluminum, brass, and copper, whereas high-temperature welding is used for steel, stainless steel, and other stainless steels.
The main difference between Weld-On 4 and other brands of filler metal is that it does not contain lead, which makes it safer for people who are allergic to lead or who want to avoid using a product that contains lead.
What is Weld on 4 Used For?

How do Weld-On 3 and Weld-On 4 Compare?
Weld-On 3 and Weld-On 4 are both high-strength adhesives that provide a permanent bond to metal.
Both welders are used for similar purposes: repairing minor surface rust on steel and filling in holes or cracks in metal. They both come in a two-part mix that must be mixed together before use (which makes them easy to use). Both products have similar applications and should work equally well when applied correctly. However, they differ in the following respects:
Weld-On 4 is similar to Weld-On 3, but it has a stronger adhesive strength and also has a longer open time than Weld-On 3. Weld-On 4 can also be used for making repairs to metal surfaces such as aluminum and steel.
Another difference between Weld-On 3 and Weld-On 4 is their viscosity. Weld-On 4 is a thicker adhesive than Weld-On 3, so it can take longer to dry. However, Weld-On 4 also has better bonding strength because it’s capable of filling microscopic pores on surfaces.
How to Use Weld-on 3 and 4:
- Clean the surface of the metal to be welded with alcohol or acetone. This will remove any dirt or grease from the surface and allow for better adhesion between the two pieces of metal being welded together.
- Apply a thin layer of Weld-on 3 to both pieces of metal that are being welded together. Make sure each piece is thoroughly coated with glue before attempting to join them together.
- Allow the adhesive to dry for at least 15 minutes before using it to ensure maximum strength when used as a permanent bond between two pieces of metal.
