The world has seen a substantial increase in the number of welding processes , and metalworking specialists are constantly researching ways of creating more. Plasma cutting is also a valuable skill to master, and when paired with welding it can take a piece to the next level. In the automotive industry, welding aluminum has gained popularity.
The laser was originally developed as a communication device, but the enormous amount of concentrated energy in a small space proved to be a powerful heat source. It can now be used for cutting metals and nonmetals, especially in automotive metalworking operations. Welding machines are getting more technologically advanced, however welding has never been more simple.
These welders and plasma cutter take the fear out of welding, and make it simple for just about anyone to produce quality welds. Future Welding Trends. Welding operations must be completely integrated into agile manufacturing processes and control schemes. In addition to this, welding engineers will develop new materials and adapt existing materials to be welding into world-class, fabricated products.
It is hypothesized that welding will continue to become even simpler, in turn making metalworking machines more advanced. The competition among other welding companies to create more user-friendly and durable machines will drive advancements.
You might also see a rise in more exotic materials, specifically in Aerospace engineering. Electron-beam welding will push to the future. This advanced form of welding is excellent for joining dissimilar and hard to weld metals. Whichever way you look at it, welding has always been an important trade. Thanks to past and present welding technicians and engineers, it seems that welding has a rich future ahead.
Sub Arc. Friction Stir Welding. New innovations are still occurring in the welding industry. Our recent inventions optimize MIG and TIG shielding gas flow at the weld start Patent Number 6,,; figure left and Patent Numbers 7,, and 7,, These devices reduce the excess "gas blast" at each weld start.
Reducing shielding gas waste can save a MIG user typically about half the gas being used while improving weld start quality. Our Patent 7,,, December , defines a device that allows most flowmeters to be locked at the desired settings avoiding excess wasted gas. Reducing waste is very important in a competitive world environment. These welding helmet designs not only filter the air entering the helmet they also cool the air using a Thermoelectric Cooling Module. Research shows cooling the head helps cool the body.
Excessive heat is a common complaint of welders. This helmet helps solve the excess heat problem by providing cooled, clean, breathable air. Note patent covers a number of configurations including typical welding PAPR construction and possible use of a backpack arrangement. With the new very low allowed manganese fume levels 4 times lower than Phosgene, the WW I poison Gas! Welders will like wearing it versus a conventional PAPR or quality respirator since it also helps their hot working environment!
We are searching for a company to license these designs, including large fabricators employing a number of welders who would benefit from the reduced heat and better environment.
Have a MIG Welder? Improve Weld Start Quality and. He wrote:. Thanks for the professional service and a great product. That caused air to be sucked into the gas stream causing poor weld starts. With the replacing their existing hose, the peak flow surge at the weld start was about 50 CFH.
Total gas use was cut in half. Kyle Bond, President, quickly saw the improvement achieved in weld start quality as a significant advantage! Kyle, an excellent automotive painter, was well aware of the effects of gas surge caused by pressure buildup in the delivery hose when stopped.
Soon after the introduction of CO 2 welding, a variation utilizing a special electrode wire was developed. This wire, described as an inside-outside electrode, was tubular in cross section with the fluxing agents on the inside. The process was called Dualshield, which indicated that external shielding gas was utilized as well as the gas produced by the flux in the core of the wire for arc shielding. This process, invented by Bernard, was announced in , but was patented in , when the National Cylinder Gas Company reintroduced it.
In , an inside-outside electrode was produced that did not require external gas shielding. The absence of shielding gas gave the process popularity for noncritical work. The electroslag welding process was announced by the Soviets at the Brussels World Fair in Belgium in It had been used in the Soviet Union since but was based on work done in the United States by R.
Hopkins, who was granted patents in The Hopkins process was never used to a very great degree for joining. The first production use in the U.
It was announced in December for the fabrication of welded diesel engine blocks. The process and its variation, using a consumable guide tube, is used for welding thicker materials. The Arcos Corporation introduced another vertical welding method, called Electrogas, in It utilized equipment developed for electroslag welding but employed a flux-cored electrode wire and an externally supplied gas shield.
It is an open arc process since a slag bath is not involved. A newer development uses self-shielding electrode wires and a variation uses solid wire but with gas shielding. These methods allow the welding of thinner materials than can be welded with the electroslag process.
Gage invented plasma arc welding in This process uses a constricted arc or an arc through an orifice, which creates an arc plasma that has a higher temperature than the tungsten arc. It is also used for metal spraying, gouging and cutting. The electron beam welding process, which uses a focused beam of electrons as a heat source in a vacuum chamber, was developed in France. In the United States, the automotive and aircraft engine industries are the major users of electron beam welding.
Friction welding, which uses rotational speed and upset pressure to provide friction heat, was developed in the Soviet Union. It is a specialized process and has applications only where a sufficient volume of similar parts is to be welded because of the initial expense for equipment and tooling. This process is called inertia welding. Laser welding is one of the newest processes. The laser was originally developed at the Bell Telephone Laboratories as a communications device.
Because of the tremendous concentration of energy in a small space, it proved to be a powerful heat source. It has been used for cutting metals and nonmetals. Continuous pulse equipment is available. The laser is finding welding applications in automotive metalworking operations.
