The joining of two pieces of metal may be accomplished by the use of a welding technology called Laser Welding Works in Hyderabad. The material being welded is melted by the tremendous heat generated by the laser beam, which also helps to fuse the material together. Because welds need to be precise and of high quality, sectors including the automotive, aerospace, and electronics production industries often turn to laser welding as their method of choice.
Laser Welding is a welding technology used to create a strong joint between several metal components with laser. Laser produces a beam of high-intensity that is concentrated into one spot. This concentrated heat source enables fine, deep welding with high welding speed.

10) welder with no experience can do a good job
MIG Welding features
MIG/MAG welding is a versatile technique suitable for both thin sheet and thick section components. An arc is struck between the end of a wire electrode and the workpiece, melting both of them to form a weld pool. The wire serves as both heat source (via the arc at the wire tip) and filler metal for the welding joint. The wire is fed through a copper contact tube (contact tip) which conducts welding current into the wire. The weld pool is protected from the surrounding atmosphere by a shielding gas fed through a nozzle surrounding the wire. Shielding gas selection depends on the material being welded and the application. The wire is fed from a reel by a motor drive, and the welder moves the welding torch along the joint line. Wires may be solid (simple drawn wires), or cored (composites formed from a metal sheath with a powdered flux or metal filling). Consumables are generally competitively priced compared with those for other processes. The process offers high productivity, as the wire is continuously fed.
Manual MIG/MAG welding is often referred as a semi-automatic process, as the wire feed rate and arc length are controlled by the power source, but the travel speed and wire position are under manual control. The process can also be mechanized when all the process parameters are not directly controlled by a welder, but might still require manual adjustment during welding. When no manual intervention is needed during welding, the process can be referred to as automatic.
The process usually operates with the wire positively charged and connected to a power source delivering a constant voltage. The selection of wire diameter (usually between 0.6 and 1.6mm) and wire feed speed determine the welding current, as the burn-off rate of the wire will form an equilibrium with the feed speed.
TIG Welding Process Characteristics
In the TIG welding process the arc is formed between a pointed tungsten electrode and the work piece in an inert atmosphere of argon or helium. The small intense arc provided by the pointed electrode is ideal for high quality and precision welding. Because the electrode is not consumed during welding, the TIG welder does not have to balance the heat input from the arc as the metal is deposited from the melting electrode. When filler metal is required, it must be added separately to the weld pool. TIG Welding Process Characteristics

Welding using a laser, offers a number of benefits, including the following:
Welds that are exact and constant may be produced by using laser welding because of the precision with which the heat input can be controlled.
-
- The fact that Laser welding works in Hyderabad is a quick process makes it an excellent choice for manufacturing in huge volumes.
- Welds produced by laser welding are of high quality, with minimum distortion and a reduced likelihood of having faults.
- Laser welding is a versatile technique that may be used to connect a variety of materials, including metals and polymers, among others.
- The process of laser welding is readily amenable to automation, which results in lower labor costs and higher overall output.
The processes of conduction-restricted welding and keyhole welding are the two essentially distinct modes in which laser welding may function. The amount of power that is distributed evenly throughout the beam when it strikes the workpiece will determine the manner in which the laser beam will interact with the material that it is welding.
When the power density is generally lower than 105 watts per square centimeter, a process known as conduction-restricted welding takes place. The laser beam is unable to enter the material since it is only absorbed in the surface when it first hits it. Welds that are restricted by conduction often have a high width-to-depth ratio, though.
A keyhole mechanism often uses larger power densities in order to complete the laser welding process. When the laser beam is focused on a spot that is small enough to produce a power density that is typically greater than 106-107 W/cm2, the material in the path of the beam not only melts but also vaporizes before significant quantities of heat can be removed by conduction. This occurs before the laser beam is able to remove significant quantities of heat by conduction.
The work piece is then drilled with a concentrated laser beam, creating a cavity inside of it that is referred to as a “keyhole” and is filled with metal vapor
This expanding vapor or plasma helps to prevent the molten walls of the keyhole from collapsing into this hollow by contributing to the prevention of the collapse.
In addition to this, the production of this keyhole results in a significant improvement to the laser beam’s ability to couple with the workpiece. After that, deep penetration welding may be accomplished by moving the joint that is being welded in relation to the laser beam or by moving the keyhole along the joint that is being welded. Welds produced in this manner have a depth-to-breadth ratio that is much more than 1.
The weld is formed when a portion of the molten material at the leading edge of the keyhole travels around the keyhole cavity to the rear, where it cools and solidifies to create the weld. This process is driven by the force of surface tension. This results in the weld cap having a chevron pattern, with the points of the pattern pointing rearward toward the spot where the weld began.
