Precision Welding Technology

Needs And Advantages of Precision welding

Precision welding technology is not a particular welding process, rather a set of welding technologies that work at micro level and deliver quality welds, which 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.  Few examples of precision welding process are as follows:

" Nd:YAG pulsed laser welding
" Gas Tungsten Arc Welding
" Micro Resistance Welding
" Micro Ultrasonic Welding

Precision welding technology is the need of the hour, as the experts confess! In the wide array of fields like, defense, aerospace, medical, plastic injection molding, machining, casting, airbag, calibration, and other custom instrumentation industries, the need of precisely made welds is utmost, and it simply can't be ignored. Research laboratories and institutes also have unavoidable need of precision welding equipment and its application in various kinds of instruments and equipments.

One of the major advantages of precision welding technology is it reduces cost of the welding process, the weld produced is of topmost quality and the wastage is far less as compared to conventional processes of welding.

Need of precision welding technology

The need of precision welding appears obvious and immediate, as there is a large demand of micro products such as batteries, capacitors, sensors, pressure devices, light-bulb filaments, vacuum tubes, thermocouples, metal bellows and seals, and surgical instruments, which can't be produced without the help of micro or precision joining processes.

The most popular processes used for precision welding are gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG); and plasma welding. These processes have advanced in their effectiveness and applications with the thickness of 0.003" can be welded using precision welding processes.

Space technology, aircraft, and medical instruments are the most important areas, where the science dealing with welding processes concentrates their efforts. Precision and micro welding are truly the most fitting welding processes that have fulfilled the demands perfectly and they continue to grow!

Micro-Precision Welding

Precision welding technology has advanced more to create another niche in welding, known as the combination of two types that we have talked about earlier-micro-precision welding. Micro-precision welding is an emerging technique for repairing damaged, worn, or faulty work-pieces. This technique allows small amounts of metal to be applied to the work-piece surfaces without causing significant thermal changes to the parent material, which is the most critical point for any welding process. Filler wires as fine as 0.005 inch can be used. Very, very small pieces can be joined together using the micro-precision welding process.

Advantages of precision welding

Some of the salient advantages of precision welding technology are given below:

" Precision welding process provides quick and efficient weld quality, which is required in almost all the advanced fields of technology.
" Lesser wastage of material is involved in precision welding.
" Micro and intricate shapes can be welded, and very fine pieces of metal and other materials can be joined successfully.
" Precision welding provides high productivity and reduced cost for its operation.
" The heat-affected-zone (HAZ) around the welded joint is far less, which helps in making a stronger and defect-free weld joint.
