"Since most EB welding is performed inside a vacuum chamber, it is an excellent fit for joining advanced materials used in such industries as aerospace, power generation, medical and nuclear which need to be produced in a vacuum environment to protect them from oxygen and nitrogen found in an open air environment, " he said. Also, for a given penetration and gun-to-work distance helium shielding permits welding at a significantly higher welding speed. This paper provides a technical overview of the unique features of the electron beam welding process including several applications. Electron Beam welding was developed in the late 1950's, came of age during the 1960's, and today is a tried and true technology that remains unsurpassed for weld penetration, weld purity, and precision repeatability. Electron beam welding joint design and development. In today's eb welders a machine program constantly monitors the actual values of all electrical parameters and compares them to the set values. This is will prevent crack propagation from the unfused section of the joint. This combination of dynamic movement and fast solidification may result in vapor pockets created by a too rapid solidification of the molten material behind the beam.
Electron Beam Welding Joint Design And Layout
The amount of power a laser can apply to a work piece is limited by the reflectivity of molten metal. Modern electron beam welding machines are controlled by PLCs equipped with working tables or numerically controlled welding positioners enabling the automation of welding processes and provided with various control and safety systems aimed to maximize the operator's protection against radiation and carry out technological processes in the vacuum [43]. Virtually all metals can be welded with an electron beam. There are two forms of laser welding: heat conduction welding and keyhole welding. The whole assembly is some 2 m in length. Additional testing, such as radiographic inspection and ultrasonic inspection is available as well. Non-Vacuum EBW: Non-vacuum welding is done at atmospheric pressure though the EB gun must be held at a pressure of 10– 4 torr or less for stable and efficient welding. Filler wire diameters are generally small with a maximum of about 0-5 mm and the wire is fed into the leading edge of the small weld pool. Electron beam welding joint design.com. As a result, deep-penetration welding is distinguished by great efficiency and fast welding speeds. The high heat intensity of electron beam welding results in a very narrow fusion zone with minimal distortion (Figure 2), so it is possible to weld machined components in the finished condition.
The seam tracking data is then fed back to the optic controller, which translates the information to reposition the galvo motors in the head to direct the laser beam to the required location. EBW - Higher Purity, Deeper Weld Penetration. Other welding processes rely mainly on heat conduction to transfer energy from the welding device into the part at the point where the welding device touches the surface of the material. Let's cover some key points that make electron beam welding stand out from other welding methods. Keyhole welding (see Figure 1) requires extremely high power densities of about 1 megawatt per square centimeter. On top of that, EBW works at a rapid rate, making it one of the fastest processes in assembly welding. The electron beam welding process is widely used in this industry to join new and to repair used components. And now be more broadly applied, opening up opportunities not feasible in the past. This type of configuration can also lend itself to finish machined details though the additional material used to locate the joint is sometimes removed after welding. Keys to laser welding lap and edge joints | Laser Focus World. Basic Square Groove Welds. The beam is moved toward the workpiece by the system of vacuum passes, i. e. the system of nozzles gradually reducing vacuum to atmospheric pressure. A lower power tacking pass with the electron beam helps to maintain alignment prior to a full penetration pass. The solution adopted involved pre-weld tacking at low power followed by 120° of full weld depth and completed by a full-circumference weld of full-depth commenced on the opposite side to the 120° of pre-weld.
Electron Beam Welding Joint Design And Development
The result is a deep, narrow, vapor-filled hole, or keyhole, surrounded by molten metal. The addition of nickel shim may also be useful to achieve the desired ratio of austenite to ferrite for corrosion protection. The configuration also provides clearance for a shielding gas nozzle if shielding gas is required for aesthetic purposes or for metallurgical reasons in certain metals such as titanium. This results in a very concentrated (approx. Instead of long, rigid clamps to hold the entire seam in place, multiple clamps ensure proper contact between the two sheets over a large area. Electron beam welding joint design and function. Laser welding uses a beam of light focused to a small point at the workpiece. The division of electron beam welding machines is shown in Fig. Electron beam welding machines are quite complicated, requiring skilled operators to achieve optimal results. Narrow, deep welds produce less heat input, which creates a small HAZ and limits distortion. Of the molten weld pool. Puddle welding is accomplished by manual manipulation of the workpiece under the beam, at low power, to locally fuse surface defects in materials or welds.
Electron beam welding is a process that utilises the heat from a high-velocity electron beam to form a weld. 5 mm for thicker materials to ensure repeatable fusion that accounts for variation in production. Joint design for welding: the pros and cons of groove joints. The beam is introduced to the joint at a slight angle and can produce a "double fillet" effect on thin materials. The electron beam can be focused to create a small weld area, which makes it ideal for welding delicate parts or complex designs.
Electron Beam Welding Joint Design.Com
The component must be fixtured and moved under the electron beam, as even though you can build in an extremely complex series of motions, simple tooling motions contribute to consistent and accurate alignment in the long term. The latter also benefits from a higher frequency beam pattern deflection that, to a large degree, reduces the spiking at the root of a weld. Applications and Materials. Consider welding titanium: When heated, titanium becomes extremely reactive to the gases in air, resulting in carbides, nitrides, and oxides, which cause brittleness and can reduce fatigue resistance and notch toughness in the heat affected zone of the weld. The size of the vacuum chamber limits weld size for traditional EBW. Inspection Techniques. The EBW equipment uses magnets to focus the electron beam. Fit-up is critical, and fixturing is important to avoid misalignment and concentricity problems. "Some parts and their associated welding fixtures may be too large to fit into the EB welding chambers available, " said Rugh. As an example, the welding of precision gears for the commercial aviation or medical device industries is an excellent application for EB welding. While each technology has its benefits, in practical terms, many component designs incorporate both EB and laser welds. EBW: Equipment, Joint Design and Applications | Metallurgy. Our technicians have multiple years of experience in a wide field of specific applications, such as sensor design, high-pressure weld joints, turbine and piston engine components, aerospace (civil and sports), defense and armaments.
Standards such as AMS2680, AMS2681B, AWSD17. Contact us to know more about our EB welding capability, and how we can help you achieve a high-quality product using EB welding. If the focus position shifts outside this area, expect the process results to change. A reliable and simple inspection method is also desirable.
Electron Beam Welding Joint Design And Function
Optical tools allow for adaptability in welding. Susceptibility to liquation cracking in the 'nail-head' region of the HAZ is promoted by the stress/strain. This is a great advantage when fusing titanium and its alloys. This activity is carried out within a vacuum chamber thus preventing the beam from being defused by air molecules and also providing a virtually inert atmosphere. Make sure the workpiece parts have been thoroughly cleaned. The ability to process in this manner is provided via a combination of features, including optical seam tracking, integrated clamping, and beam oscillation capabilities, in one tool—the Scansonic FSO (Flange Welding Optic).
The solutions noted hereafter can offer strong potentials for weight reduction and open up enhanced design opportunities. This joint preparation can be expensive, but is used in fatigue-critical applications where the notch effect of non-fused material and a change in cross-section is minimized. The escaping material keeps the channel open. Tier Joint — Figure 17. In this process, the laser beam not only melts the metal but also produces vapor. The joint must be satisfactorily strong in service and capable of being consistently produced in the quantities and the requisite quality desired. There are materials where it is advantageous to use filler metals, e. avoiding weld cracking in 6000 series aluminum. The joint information below helps define and clarify the tooling and fixture options for a new welding project. Assemblies can be welded using finished or part finished details using a vast range of materials. Therefore, fixturing is critical in these joint configurations to ensure high positional repeatability and minimal gap. Plug Weld with Top Scab — Figure 12.
Electron Beam Welding Joint Design And Procedure
Titanium and magnesium alloys are materials that often require this approach to providing adequate filler material. This allows for flexibility when designing your parts and weld locations. Slower weld travel speeds produce a shallower temperature gradient in the HAZ and are beneficial towards reducing liquation cracking susceptibility. The modification to the integral backup in Figure 3 is sometimes used for crack sensitive materials. Lap welding has many different considerations.
This ability to apply exceptionally high levels of heat energy to a very small area makes it the preferred welding method for many hard-to-weld materials. According to John Rugh, Marketing and General Sales Manager for PTR-Precision Technologies, Inc. (Enfield, CT), EBW is a process that will be in use for a long time. High voltages are supplied into an electron gun, which then expels a high-velocity stream of electrons with the help of cathodes, anodes, focusing coils, and magnetic fields. It has one of the highest ranges of material combinations and part geometries, is extremely controllable and repeatable, and is one of the easiest to automate (see Figure 2).
00013 mBar) with the electron gun at a higher pressure of around 1E-6 torr (0. One of the parameters provided by the eb process is the capability to change dynamic movement of the molten material by influencing the size of the key hole. All grades of steel can be welded, as well as low melting alloys such as aluminum and magnesium, and high melting materials such as Nickel- and Cobalt-based alloys. The allowable gap is typically 10% of the thinnest material or less than 50% of the weld beam diameter. The vapor in the keyhole also absorbs laser light and is partially ionized.
In this technique the stream of electrons penetrate the surface of the work to a distance of about 25 microns. For a design engineer, this meant that a very precise weld could be applied in a highly repeatable way.
