Escapes – this is how businesses call product defects that has been sent out of the production process, those that are NOT SUPPOSED to be sent out to customers. They mean trouble for a lot of businesses. Just imagine all the after-sale repair this will cost, when in fact, these should be avoided and prevented as early as soon as they are detected in the process!

Escapes may not be that much of a big deal for regularly priced goods and necessities that we buy over the counter, but it’s a totally different case when we talk about aerospace escapes. Escapes related to airplanes and their accessory equipment should be taken seriously. If not identified at the earliest time possible, escapes can cause major casualties, including people’s lives. These flawed parts may be attached to commercialized planes without anyone recognizing them to be defective. Have we not heard enough from the news on the many airline crashes and fatalities caused by faulty engines, hydraulic fittings or fuel lines have been? If you still can’t grasp how BIG the expense can be for these escapes, there was one instance when 20,000 parts were improperly processed, thus, had to be recalled at a staggering cost of $20,000,000! Imagine how much loss that is!

As quoted by Chet Date, Director of Quality Systems & Regulatory Compliance at Honeywell Aerospace: “Escapes are a serious issue for the aerospace industry. Recalls are costly and problematic as aircraft are complex machinery operating in a challenging environment. It is vital that non-compliant aerospace parts are identified and communicated as quickly as possible to prevent serious accidents.” As an additional statistic, 9 out of 10 aerospace manufacturers risk serious defects. This is very alarming in today’s fast-paced lifestyles where travel around big distances is just a plane ride away.

The aerospace industry needs welders to weld critical component parts. Of course, welders are expected to know a wide range of welding skills but how are companies who hire welders assured of the quality of work done? Here now comes the need for CREDIBLE CERTIFICATION that you should look for in a welder. How specialized are aircraft’s when it comes to welding? Very specialized to a point where aerospace welding involves microscopes. It is not your typical kind of welding with sparks and big welders! Because of these risks, Primes like Boeing, Airbus, Gulfstream and their sub-tiers only use vendors that are Nadcap Accredited or Approved in addition to the high-skill level that the task needs.

What is Nadcap?

This is an accreditation process that audits vendors and service providers that will greatly benefit industry input at critical points with the aim of minimizing the workload of the customer whenever possible. From various representatives within the industry, they will have to collectively decide on which processes to audit and which provider will be granted Nadcap accreditation based on the results of a rigorous audit procedure.

Why Nadcap?

Nadcap is a way to manage the industry primarily to assess whether service providers adhere and conform to certain standards in their business processes. In the same way as to how other accrediting associations operate, technical experts from the Industry and the Government are brought together to lay down accreditation requirements, list down the accredited Suppliers and to define operational program requirements. The procedures for accreditation, in turn gives the businesses the quality assurance that they are looking for in welding companies.

What are the Various Orbital Welding Applications?

Orbital welding applications is growing more and more as we realize the benefits of this welding kind. Learn more about orbital welding equipment, application and materials.

Orbital welding gives high quality welds

Orbital welding is a special area of welding where the arc is mechanically rotated 360 degrees around a static work piece in a continuous process. This process was developed to address the issues on operator error in gas tungsten arc welding (GTAW) processes. In orbital welding, computer-controlled process runs with only very little intervention from the operator. This process is specifically used for high quality, repeatable welding. The orbital welding process was invented more than 50 years ago as a way to solve the issue of operator error in GTAW. Read on as we learn more about orbital welding applications, equipment, process and materials.

The main components of each orbital welding machine as the controller and power source, the welding head and a wire food mechanism. Welding materials of certain types and sizes also requires the use of a water or coolant system. There are several orbital welding equipment factors that can have an influence on the welding result. These aspects include the magnitude, arc length and pulse frequency of the welding current, thermal conductivity, welding speed, weld preparation, inert shielding gas, filler material and parent material. Ultimately, a quality weld is achieved via detailed knowledge of how to precisely adjust these parameters for individual welding task.

It’s hard to achieve the highest standards of safety and quality in manual welding

This is because of certain welding positions, that often lead to faulty welds because of restricted access in these positions. To have complete control over the weld pool, a perfect balance should be maintained between gravitational force and surface tension at each torch position. By using mechanized variants of the technique, certain parts of the welding process are handled by mechanical components. Take note that a welder will always control and monitor the process. Ideally, all welding parameters is programmed before welding starts. However, in practice, the presence of variable constraints means it’s mostly necessary for the welder to make corrective interventions.

Orbital welding has almost always been exclusively done by the tungsten inert gas technique using non-consumable electrodes, with extra cold-wire feed where necessary. The easy control of heat input makes TIG welding the best welding method for fully orbital welding of tubes with specialist orbital welding heads that incorporate a clamping device, TIG electrode and shielding gas chamber. Various kinds of metal can be welded: steels, nickel alloys, copper, aluminum, titanium and associated alloys. Carried out in an inert atmosphere, this technique gives results that are very clean, free from unwanted spatter and have low particle counts. This allows the highest depands to be met when it comes to the optical and mechanical properties of a weld seam.

Because of its ability to realize high purity results, orbital welding found its place in making clean-room components for the semiconductor industry. This application has now expanded to the construction of equipment and pipework for diverse industries like aerospace, shipbuilding, biotechnology, food processing, automotive engineering, pharmaceuticals and chemical engineering. Automated orbital TIG welding is also used in making power stations. The construction of materials used should be able to withstand the huge mechanical loads made by the high temperatures and pressures made by the media in the tubes.

Pores, notches and inclusions in the weld seams should be avoided at all costs because these make weak points that can lead to subsequent formation of cracks.In turn, these can have serious consequences when it comes to component failure. This means that tubes are mostly made from nickel-based materials that have walls of up to 200 millimeter thick. A manufacturer was able to come up with an orbital narrow gap welding system with hot-wire feed especially for this purpose that uses running gear that moves on a guide ring fixed around the tube. This new variant gave way to a lot of interest in the sector, following the worldwide boom in power station construction that field the continued search for increasingly productive manufacturing methods using new high temperature steels.

Along with the current methods of using hot wire and TIG orbital welding, there’s also a steady process in the development of FCAW/MAG/MIG welding that allows for a new range of new applications. Orbital welding can give reliable welding of reproducible quality with a range of techniques. This can be done to a high standard even when using unusual materials, small tube diameters, thick walls and in difficult working environments. Although more expensive than conventional welding equipment, productivity is also significantly higher than conventional TIG.

Getting To Know More About Certified Welders

The Importance Of Certified Welders

Certified welders are skilled individuals who utilize welding tools to join together two different materials. There are a variety of welding tools available, each having its benefits. Welding has long been around for so many years, but it did not become completely industrialized until the 1990s. And just like all tradesman, a welder needs to go through welding training and apprenticeship before becoming a certified welder.

Basic Description Of A Welder

Function

Generally, welders join metals like copper, aluminum, steel or a variety of plastics and polymers, utilizing specific tools for each task. Welders need to maintain good dexterity and attention to detail because this can be a delicate job. They also need to possess knowledge of different materials with technical knowledge on how to effectively join material.

Features

A welder is the main tool that is used in welding. This is a device that emits a form of energy that will then be used to merge two materials together. The most common kind of welder is a gas flame. The flame will heat to a temperature that is high enough to melt and join both materials. An electric arc is also relatively common. This provides an electrical breakdown of gas to discharge plasma, providing a non-conductive mass that requires proper welding technique.

History

Welding was already around back in the Bronze Age but it was not until the Middle Ages that it began to take shape. In the early 19th century, the electric arc was discovered, which revolutionized the possibilities of welding by adding precision to the process. By 1893, the first gas welders started appearing which paved the way to the invention of the blow torch. The world wars have revolutionized the welding industry because of the growing need for a bigger work force and larger scale welding facilities.

Warning

There are wide array of dangers that are associated with welding, some of which can even be life threatening. Its basic tools use a flame or electric arc so precautions need to be taken against burns in the form of long sleeves and leather gloves. Bright light is also another problem as it can cause damage to cornea and ultimately lead to blindness. To prevent this, welders need to wear shaded goggles and protective helmets. And then there is the danger of breathing in the fumes emitted by the materials joined together. Air filters should give good protection.

Considerations Before Hiring A Welder

A welder needs to go through a series of stages in their career path, just like any other tradesman. But unlike the previous times, the apprenticeship of a welder is now carrier out with an accredited trade school. Lasting for about two years, these programs will provide the welder with concrete knowledge on the welding process, tools and materials as well as safety information for a successful career because of all these, hiring a tradesman with welding certification is very important.
