Welding processes vary in many different ways, check out this quick review of the various types of welding.
Precision welding is not a particular welding process, but rather a set of welding technologies that operate at a micro level to deliver quality welds. Precision welding is used in circumstances where otherwise are difficult to get from the conventional methods of welding. Most of the advanced forms of welding processes fall in the category of precision welding. Similar to micro welding.
Micro Welding, refers to technologies and equipment designed especially for performing, as it suggests, micro-welding on tiny, thin, and delicate parts by using tightly controlled heat energy.
Laser welding is one of the major techniques used in the metalworking industries, as the concentrated energy of laser results in a better quality of the weld. Usually reserved for robotic and machine operated manufacturing.lasers can also be used for some secondary purposes such as cutting, drilling, sealing, and scribing, making the technique itself, multifunctional in nature.
Resistance welding involves the generation of heat by passing a current through the resistance caused by the contact of the metal surfaces. Pools of molten metal are formed at the weld area as the high current is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are somewhat limited and the equipment cost can be high.
Seam Welding is a resistance welding process that produces a weld at the faying surfaces of overlapped parts along a length of a joint. The weld may be made by overlapping weld nuggets, a continuous weld nugget, or by forging the joint as it is heated to the welding temperature by resistance to the flow of welding current.
Ultrasonic welding is an industrial technique where high-frequency ultrasonic vibrations are used to weld objects together, generally, plastics. This type of welding is used to construct parts and components that are too small, complex, or too delicate for the more common welding techniques. In ultrasonic welding, no other connecting methods or adhesives are necessary to bind the materials together.
Hermetic welding is a welding process that does not produce a weld but produces a seal. The main point of hermetic welding is to provide a total leak-proof joint, which can’t be provided through any other conventional welding processes
Projection welding is a versatile process for joining wire, sheet, machined & formed parts in steel, such as wire mesh, attachment of brackets, etc in sheet metal assembly, and welded nuts and bolts.
Orbital welding has the ability to make high quality, consistent welds repeatedly at speed
An orbital welding system will drastically outperform manual welders, many times paying for the cost of the orbital equipment in a single job.
Underwater welding, is a unique form of welding and has got multiple applications, which are rare to be worked upon by other conventional methods of welding. Underwater welding is widely used in offshore structures such as oil drilling rigs, pipelines, shipping repair, and underwater platforms.
This is the basic form of welding that uses a basic stick electrode. This electrode contains both the welding filler metal plus a shielding coating of flux that prevents contamination of the weld. Arc welding is used in manufacturing and fabrication shops and factories worldwide and is the basis of all the welding types.
