Welding: An Introduction

Welding is commonly finished to affix two supplies, often metals. Nevertheless, nowadays, the process of welding is used for becoming a member of 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, longitudinal vibrations are despatched to the weld surfaces whereas parallel vibrations are answerable for profitable metal welding. Also, in case of metal, friction does not lead to simple melting of the surface. In plastic welding, the fabric melts attributable to frictional motion, and that too at a much lower temperature compared to that put in use throughout the metal joining process.

Welding Tools

Because the metal welding trade requires fusing of thicker materials, the equipment used for the purpose are totally different than these in use for glass or plastic. Although both types of welding tools are manufactured on the basis of the frequent principle of acoustics, there are some differences in their shapes; which in turn sends out completely different kinds of vibrations to the weld surfaces.

Essential Levels of Plastic Welding:

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

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

Heating: Intermolecular diffusion is allowed within the heating stage for better fusion.

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

Plastic soldering makes use of different types of processes equivalent to spin, vibration, laser, ultrasonic, and so on and every of these processes differ from each other of their individual methods.

Glass Welding Process

Glass welding is usually achieved at the time of producing glassware, establishing neon signs, flash tube and scientific apparatus. Also, bottles and jars require glass welding to join the totally different glass molds. In glass welding, the glass is melted into a thick liquid mass, which in turn is heated under very high temperature. However, the temperature required in glass welding is dependent upon the types of glass involved within the process. The melted glass is heated utilizing a particular type of gas torch.


Whether it is about welding metals or glass, the overall process is so simple as heating and joining with the use of technology. Nevertheless, there exist sure differences, which must be mastered for finest results.

Welding is essentially the most commonly used process for joining supplies and helps many alternative methods. It’s used in the manufacturing of common tools and apparatuses used in different industries.
