How Are Glass and Plastic Welding Different From Metal Welding?


Welding: An Introduction

Welding is commonly achieved to affix supplies, normally metals. Nevertheless, these days, the process of welding is used for joining plastic and glass items too. Metal welding process is fundamentally different from plastic welding or glass welding. Read on for more.

Difference within the Vibrations

In case of plastic welding, lengthyitudinal vibrations are despatched to the weld surfaces whereas parallel vibrations are answerable for successful metal welding. Also, in case of metal, friction does not lead to easy melting of the surface. In plastic welding, the material melts resulting from frictional motion, and that too at a much lower temperature compared to that put in use during the metal becoming a member of process.

Welding Instruments

Since the metal welding trade requires fusing of thicker supplies, the equipment used for the aim are completely different than these in use for glass or plastic. Although both types of welding tools are manufactured on the basis of the widespread precept of acoustics, there are some variations of their shapes; which in turn sends out totally different kinds of vibrations to the weld surfaces.

Predominant Stages of Plastic Welding:

Plastic welding is primarily done to create a stronger molecular bond between two thermoplastics. The process consists of three main steps:

Pressure: Pressure helps in flattening the surfaces of the objects to be welded and has to be applied for keeping their different parts in proper orientation.

Heating: Intermolecular diffusion is allowed in the heating stage for higher fusion.

Cooling: This stage is vital for solidifying the newly created molecular bond and leads to proper weld strength.

Plastic soldering makes use of different types of processes such as spin, vibration, laser, ultrasonic, etc and every of those processes differ from one another of their particular person methods.

Glass Welding Process

Glass welding is usually accomplished on the time of producing glassware, developing neon signs, flash tube and scientific apparatus. Additionally, bottles and jars require glass welding to hitch the different glass molds. In glass welding, the glass is melted into a thick liquid mass, which in turn is heated under very high temperature. Nonetheless, the temperature required in glass welding will depend on the types of glass concerned within the process. The melted glass is heated using a particular type of gas torch.


Whether or not it is about welding metals or glass, the overall process is so simple as heating and becoming a member of with the use of technology. However, there exist certain differences, which need to be mastered for greatest results.

Welding is the most commonly used process for becoming a member of two materials and helps many various methods. It is used within the manufacturing of widespread instruments and apparatuses used in totally different industries.
