Creating Technologies - Laser Welding Machines

Laser Welding Machines:

Let us understand what does laser welding mean. It is a process which requires  an access to the weld zone from only one side. The laser weld is formed by the intense light that heats the material faster. This process can be calculated in milliseconds.

Laser stands for Light Amplification by Stimulated Emission of Radiation. This welding is of the most technically forms of welding. Its application is used in almost all industries i.e. from aerospace to fine jewellery making. 

Technology inception happened when Einstein predicted stimulated emission, which is the basic principle of laser.

It was then in the year 1967 that this (laser) was used in welding and cutting. There were certain experiments in the same year which were done through this technology (laser) using Oxygen as an assisting gas and Carbon Dioxide as concentrated. This project was lead by Dr. Peter Houldcroft.

Later, being successful in these experiments,  Laser cutting led to the foundation for laser welding which involves melting of metal than punching the same. 

This process happens by using highly concentrated beam light on a very tiny spot or need area to be mended, hence the affected area absorbs the light and gets more energetic. 

These laser beams are so powerful that the material melts and thus it results in the breaking of bonds within the atoms. 

This type of welding is also used for enjoinment of plastics. 

There are various weld joints done by making use of laser welding:

1. Butt welding
2. Filler welding
3. Overlap welding
4. Edge flange weld

There are also two different types of laser welding which are as follows:

1. Heat Conduction Welding: This process includes the heating above the melting point but below the vaporisation of the same. This process is used for those welds which do not need high weld strength.
2. Keyhole Welding: This process makes a deep hole  by heating up the  area to be affected on the metal also allowing the affected area to vaporise.

This process of laser welding proves highly advantageous:

The whole welding process can be easily automated using a CAD/CAM setup
No electrode is used in the process
No form of tool wear occurs
Laser welding is highly specific in targeting
High-quality welds are obtained

Laser Welding Machines for Jewellery

As mentioned above this technology also proves to be efficient in jewellery making industry. As Jewellery making needs high precision welds, also they need to be very fine or light but at the same time weld needs to be stronger.
Here Spot welding is an important aspect . This process tends to harden the material by reducing its fatigue strength. 

It has Automatic Stand-By Function
It also includes multiple unit controls
It focuses on the digital connection system for remote self-diagnostic
It has zoom function
It carries digital magnification system with high-res screen for internal camera monitoring
It uses argon gas

Jewellery weighing scales and machines

A device used to measure weight or mass is called a scale. Scale is also known as mass scale, weight scale, mass balance, weight balance.

The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum.
Similarly there Jewellery scales which are used by jeweller to weigh semi-precious stones, diamonds and gold in carats. They often feature as portable pocket scales or precision balances with a high readability for weighing in sub-milligram divisions.

There is a wide variety jewellery scales/machines available i.e. from analytical balance which usually weigh small items such as gold leaf, diamond chips to bench and pocket scales which are used to weigh gemstones to customized jewellery which includes necklaces and bracelets.
