What Is Welding Glue
Welding glue is a type of adhesive that is used to join plastic components together.
It involves a phase change from solid to liquid and then solidification at the joints.
This method is suitable for heat-sensitive plastics and can create clean aesthetic joints with low weight and strong connections.
There are different welding techniques, such as friction welding and welding with an external heat source, as well as different gluing methods, including solvent bonding, adhesive bonding, or double-sided tape.
Welding glue, such as Homax® Welder™, is an industrial strength all-purpose adhesive that can bond porous and non-porous materials together.
It is usable in both indoor and outdoor applications and can be applied to various materials like plastic, wood, metal, rubber, vinyl, and more.
However, it is important to use this adhesive carefully as it is flammable and labeled as a reproductive hazard.
Did You Know?
1. Despite its name, welding glue is not actually a type of adhesive used in the welding process. Instead, welding glue refers to a specific process called plastic welding, where the two materials are fused together using heat and pressure.
2. The term “welding glue” is commonly used in the automotive industry when referring to the process of repairing plastic components. It involves melting a plastic rod and using it to fill gaps, cracks, or holes in the material.
3. One interesting fact about plastic welding is that it can be used on a wide range of materials, including but not limited to plastics, PVC pipes, acrylics, and even certain types of metals. This versatility makes welding glue a popular choice for many repair applications.
4. In some cases, welding glue can create a stronger bond than traditional adhesives. This is because the welding process does not rely solely on the adhesive properties of the material, but rather on the physical fusion of the two materials, resulting in a more durable and long-lasting bond.
5. Welding glue is commonly used in the construction of plastic tanks, pipes, and containers, as it provides a strong and leak-proof seal. This ensures the integrity of the structure and prevents any potential leaks or damage.
Phase Change And Solidification At Joints
Welding glue is a powerful and versatile adhesive that is specifically designed for joining plastic components. It employs a unique phase change mechanism to create a strong and long-lasting bond. This adhesive transitions from a solid to a liquid state at the joint, allowing it to deeply penetrate and securely attach the plastic parts. Once the joint is formed, the adhesive quickly solidifies, ensuring a secure and durable connection. This phase change process is crucial for guaranteeing the strength and longevity of the bond between plastic parts.

Welding Techniques: Friction And External Heat
Various welding techniques are used for bonding plastic components. One such technique is friction welding, where heat is generated by the friction between the plastic parts, causing localized melting and subsequent bonding at the joint interface. This method is particularly suitable for thermoplastics because they can soften and reform when exposed to heat.
Another popular welding technique involves using an external heat source, such as a hot air gun or a soldering iron, to melt the plastic and create a fusion between the joint surfaces. This method is suitable for both thermoplastics and thermosetting plastics, enabling a wide range of plastic materials to be welded together.
Gluing As An Alternative Assembly Method
In addition to welding, gluing is another widely used method of assembling plastic parts. Glue offers several advantages over welding, particularly for heat-sensitive plastics that may be damaged by the high heat involved in the welding process. Gluing provides a clean aesthetic joint with low weight and strong connections.
There are various gluing methods available for joining plastic components. Solvent bonding, which involves using a solvent to dissolve the surface of the plastic parts and then pressing them together, is a common technique. Adhesive bonding, where a specialized adhesive is applied to the joint surfaces, is another popular method. Double-sided tape can also be used to bond plastic parts together effectively.
Clean Aesthetic Joints With Low Weight And Strong Connections
One of the major advantages of using welding glue for joining plastic components is the ability to achieve clean aesthetic joints with low weight and strong connections. The adhesive forms a seamless bond between the parts, eliminating the need for additional hardware or external reinforcements. This results in a visually pleasing appearance while maintaining the structural integrity of the assembly.
Welding glue is suitable for use on various materials, including:
- plastic
- wood
- metal
- rubber
- vinyl
- cloth
- tile
- ceramic
- glass
- Formica®
- cement
- brick
Its versatility makes it an essential tool in a wide range of applications, both indoor and outdoor.
Bonding Porous And Non-Porous Materials Together
Welding glue, such as Homax® Welder™, is an industrial strength all-purpose adhesive that can bond both porous and non-porous materials together. This makes it an ideal choice for projects that involve different types of materials, as it eliminates the need for separate adhesives.
The adhesive can be used to permanently bond, fasten, protect, seal, and caulk various items. It provides a reliable and long-lasting bond that can withstand different environmental conditions, ensuring the durability of the assembled components.
When using welding glue, it is important to follow the recommended application process. Cleaning the surfaces thoroughly and applying the adhesive directly from the tube or using a toothpick or cotton swab for small areas ensures proper coverage and adhesion. The adhesive should be allowed to stand for 5 to 10 minutes before pressing the surfaces firmly together.
For maximum strength, it is advisable to let the adhesive dry overnight. However, it is essential to note that the adhesive reaches its maximum strength after 24 hours of drying time. During this period, it is important to avoid exposing the adhesive to heat and open flames, as welding glue is flammable and can pose a fire hazard.
It is worth mentioning that welding glue, like many industrial adhesives, is labeled as a reproductive hazard. Therefore, it should be handled with caution and kept away from children and pregnant individuals. Additionally, shipping restrictions apply, with the adhesive being prohibited from being sent to Hawaii, Alaska, or Puerto Rico.

What is the difference between welding and glueing?
Welding and gluing are two different methods of joining materials together. The main difference lies in the durability and strength of the bond created.
Welding involves fusing two like coated materials together, resulting in a strong and permanent bond. Unlike glueing, welding does not rely on adhesive interfaces, making it more resistant to wear and tear. Welded lap seams, in particular, have superior tensile strength, especially in shear directions, exceeding that of the base fabric. On the other hand, glueing relies on adhesives to create a bond, which can weaken over time and potentially lead to the parts becoming separated.
What is metal glue?
Metal glue refers to a range of specialized substances used to adhere metal surfaces together. Adhesives, epoxies, and super glues are the three main categories of metal glues. Adhesives are particularly notable as they are high-performance solutions that effectively bond the surfaces of metals, facilitating a strong and durable connection. The different types of metal adhesives boast distinct qualities such as flexibility or rigidity, transparency or opacity, as well as varying setting times to cater to specific metal bonding needs. Ultimately, metal glue serves as a versatile tool in joining metal surfaces with precision and reliability.
