TIG Manual Welding
TIG welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces the electrical energy, which is conducted across the arc through a column of highly ionized gas. TIG offers a high quality weld although generally a slower process compared to the others which requires a higher skill

Flame Soldering
Flame soldering is a thermal joining process for metallic materials that are connected with a solder during this method. The thermal energy required for this procedure is generated by burning gas in a burner. The flame melts the solder, which then connects with the material. Flame soldering is used both for manual work and in machines. With automatic flame soldering, several burners, so-called flame field burners, are used.
Some of the benefits of this process are : Simple equipment handling, Good regulation of the heat supply, Effective shielding of the solder joint through the flame, High degree of mechanization
Induction Brazing
Induction brazing is the process of joining two or more metals using induction heating. Induction heating utilizes the electromagnetic field to provide heat without contact or flame. Induction brazing is more localized, repeatable, and easier to automate compared to traditional torch brazing.
Induction brazing has been around for a long time but is only now coming into wider use due to advancements in induction heating power supplies.
The principle of induction brazing is similar to the transformer principle, where the inductor is the primary winding and the part to be heated acts as a single turn secondary winding.
Electron Beam Welding
Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. The beam of electrons creates kinetic heat as it impacts with the workpieces, causing them to melt and bond together.
Electron beam welding is performed in a vacuum environment as the presence of gas can cause the beam to scatter. Due it being a vacuum process and because of the high voltages used, this welding method is heavily automated and computer controlled. As a result, specialised fixtures and CNC tables are used to move the workpieces inside the welding vacuum chamber.
Recent developments in electron beam welding machine technology have realised a local method of electron beam welding, whereby the electron beam gun is enclosed in a vacuum box on the side of the material to be joined, rather than placing the entire workpiece inside a vacuum chamber
