What Is Solvent Welding?

With over 90 million metric tons of solvent welding used globally each year, it is an incredibly popular manufacturing method for joining plastic parts. Solvent welding is an incredibly effective way to create a strong and durable bond between two similar plastics, and is widely used in many everyday products, from medical equipment to vehicles. Solvent bonding is also used as a method of injection molding, and can create parts with very fine details and tight tolerances.

In this article, we’ll take a closer look at solvent welding and discuss its many advantages, how it works, and what materials can be used.

What Is Solvent Welding?

Solvent welding is a type of joining process used to secure two or more items together.

It’s a common, non-destructive joining process used to join a wide range of materials, from PVC pipes and ABS sheet to metal components. Solvent welding works by using a special type of adhesive solvent, which softens the components being welded, making them easier to join together.

How Does Solvent Welding Work?

The solvent welding process relies on materials that can be softened by chemical reaction. This means the surface molecules are broken down, allowing them to blend together when pressure is applied. This forms a bond between the two objects, creating a strong and secure joint.

Types of Solvent Welding

There are two types of solvent welding: manual and automatic. Manual solvent welding involves the use of adhesives, solvents and other products to create a secure bond between materials.

In automatic solvent welding, a machine applies pressure while the adhesive solvent is fed into the joint. This reduces the time needed to secure materials together, making the process more efficient.

Benefits of Solvent Welding

Solvent welding has a number of advantages, making it a popular choice for many different applications:
  • It’s an efficient and cost-effective way to join materials.

  • It allows for most types of plastic to be joined, creating very strong and secure bonds.
  • It provides a permanent solution with high tensile strength.

  • The process is fast and easy to use.

Uses of Solvent Welding

Solvent welding is a widely used process in the plastic and metalworking industries. It’s commonly used to join materials such as PVC pipes, ABS sheets, and other plastic components. It’s also used in the aviation and automotive industries, where strong and durable materials have to be joined together.
