NDI—Leak checking, Die Penetrant inspection, Laboratory Testing and Demonstration Capabilities. The Widest Range of Electron Beam Welding Services. However, these lasers require exceptionally high power (close to 100 kW), which makes them both exceptionally expensive and exceptionally dangerous to work with. In these cases performing both types of welding at the same facility streamlines the manufacturing process. Of the molten weld pool. Make sure the electron beam can fully access the weld location. Sensitive to faying surface conditions. Due to the energy density of these types of welding, the beam falls through large gaps. ADVERTISEMENTS: After reading this article you will learn about:- 1. Adaptive remote welding. Joint Considerations. Axial and circumferential welds can be performed with a rotary tilt device that is mounted on top of the x-/y-table. The welds are staggered to equalize the heat distribution in the base plate.

Electron Beam Welding Joint Design And Supply

Tier Joint — Figure 17. 16 shows weld penetration as a function of travel speed for three different power levels of a non- vacuum EBW indicating the significant increase in travel speed by increasing power for a given penetration. Autogeny, no filler metal is required. A further reduction in cycle times to this production machine has been achieved through a design change that integrates a load lock chamber in front of the vacuum processing chamber (Figure 11). The electrons penetrate the material at the atomic level, imparting their kinetic energy as they strike molecules. Medium power is generally used for weld thicknesses from 1mm to 20mm, anything over that is in the domain of high power electron beam welding. Angular Beam — Figure 5. Plug Weld — Figure 11. Square butt edge preparation demands the use of fixtures to keep the work components in the required alignment; however when fixtures are to be avoided the joint may be modified to rabbet type as shown in Fig. Examples of this condition are reinforcing rings inside a cylinder, plate-fin heat exchangers, or integral stiffened sheets.

Electron Beam Welding Joint Design And Size

Electron beam welding (EBW) uses a high-velocity beam of electrons to melt and fuse metals together. The molten metal flows around the keyhole and solidifies in its trail. A penetration weld is a trial and requires no joint preparation. The technology behind electron beam welding allows various metals to be welded together, including dissimilar metals, since it is mostly performed in a vacuum environment. But that high thermal conductivity also makes copper notoriously difficult to weld. The indexing table welder design was established as a reliable machine tool for high-volume production of assemblies several decades ago. A scribe line is used for weld joint alignment and weld tracking. Contact us to know more about our EB welding capability, and how we can help you achieve a high-quality product using EB welding. Butt welding requires high positional accuracy. The deflection coils, situated below the focus coil, move the electron beam in circles or more complex patterns for fusion zone improvement when supplied by appropriate voltages and waveforms. Product Name: Vacuum Chamber. These characteristics make EBW an extremely valuable technology. The process laboratory occupies about 4, 000 square feet within the service facility.

Electron Beam Welding Joint Design And Control

As a result, deep-penetration welding is distinguished by great efficiency and fast welding speeds. Hence, electron beam welding must occur in a vacuum, and often this is viewed as a criticism: The welding chamber has to be pumped down, and this takes time. Aerospace Control and Quality Standards. Sciaky's welding job shop offers a wide range of affordable Electron Beam (EB) welding services for customers in a wide variety of industries all over the world.

Electron Beam Welding Joint Design And Layout

Laser welding also has one of the highest initial investments, tooling costs, and weld joint fit-up requirements These must be accounted for when selecting laser welding as the joining method for your production process. The intensity of electron beams is 100-1000 times higher than arc welding, allowing deep penetration and narrow heat-affected zones. The overall dimensions of the part were 126" long, 5. A penetration weld is the commonly used trial weld technique to determine the welding parameters for a specific part thickness. Only weld electrically conductive materials (no glass, ceramics or synthetics).

Electron Beam Welding Company

In addition to being void of atmospheric gases, some impurities actually burn away during welding, and the result is the purest, cleanest weld there is. Salay Stannard, Materials Engineer for Joining Technologies, an East Granby, CT-based provider of laser cladding, electron beam and laser welding applications, said that CW lasers can achieve penetrations up to and exceeding 0. Note: Often known as bead-on-plate (BOP) weld. Laser welding allows for creativity and some freedom in part design, as long as all the essential variables are considered. Most flanges, however, are designed to enable efficient welding with current resistance welding and laser optic offerings. However, the focus position of the electron beam is dependent on various parameters as well as the accuracy of the gun assembly. Conduction, however, leads to the energy spreading out across the part as it heats, which limits penetration and increases the chances of melting or deforming the workpiece. A beam of accelerated electrons cannot be created or maintained in air because the electrons strike gas molecules and are deflected and scattered. Weld joint preparation and fit-up are especially important for the EBW and LBW processes.

Electron Beam Welding System

The structure of an electron beam welder is shown in the diagram below. Electron beam will be the primary choice when the completed assembly must be sealed with internal components under vacuum; when weld penetrations exceed 1/2"; when the material is challenging to initiate laser coupling; or when the weld must not be exposed to atmospheric conditions until it has cooled to an acceptable temperature. Geoffrey Young, General Manager of Cambridge Vacuum Engineering (MA), said, "We are seeing many modern passenger car and commercial vehicle engines that are being equipped with turbochargers. In addition to eliminating the aforementioned porosity, the use of the pattern generator can also improve the cosmetic appearance of the top bead in a secondary operation after the penetration weld. Susceptibility to liquation cracking in the 'nail-head' region of the HAZ is promoted by the stress/strain. 001" to several inches thick to be fused together. It is truly a high-quality process for joining high-quality materials.

Edge welding of dissimilar metals. If not properly set up, this gas expulsion can get trapped in the solidifying molten pool and show up in the form of porosity in the finished weld. With today's CNC controls, the beam focus as well as the beam deflection are part of the weld schedule and can be variably programmed along with other process parameters. For instance, you should avoid welds that only partially penetrate, as these are prone to root porosity even when using beam deflection. 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. The high vacuum EBW process is an excellent tool for welding dissimilar metals of different thicknesses as well as for repair welding of components impossible to salvage by other processes. In a medium vacuum EBW gun the beam is generated in high vacuum and then projected into the welding chamber with soft or quick vacuum, as shown in Fig. Today, fast beam deflection systems allow for electronic imaging of the assembly around the joint area or splitting of the electron beam to weld 3 or 4 spots virtually at the same time. However, EBW is used mainly for applications involving high precision and high production rate. Adjustments to these values can significantly enhance the stability of key holes in most welding applications. The pattern generator, unique to the eb welding process, has proven to be very powerful in stabilizing the key hole to improve the process' robustness and produce defect-free welds. Small heat input, low distortion. When alignment is critical, the self-fixtured butt joint in Figure 10 eliminates the need for elaborate tooling and extensive tack welding.

The molten low and medium carbon materials mix together without posing any problems. Assemblies can be welded using finished or part finished details using a vast range of materials. With both methods, the laser beam is optically focused on the workpiece surface to be welded. Energy is thus given less time to dissipate into the interior of the workpiece. About the Publication.

Acetone is a preferred solvent for cleaning the components for EBW; however acetone being highly inflammable needs to be handled very carefully. The work chamber may be filled with helium as it offers less obstruction to the EB and gives better penetration shape than obtained with argon or air as atmosphere. Also, there is a probability of evaporation of high vapour pressure metals during welding. The process puts a minimal amount of heat into the workpiece, which produces the smallest possible amount of distortion and allows finish machined components to be joined together without additional processing. Additional considerations: Fit up is important for groove joints, especially for laser and EB welding. Similarly to plasma welding, the EBW process can be run in low power, medium power and high power aka keyhole mode. Pre- or Post-Weld Machining.

The distance from the focus surface to the smallest point is called focal length. Additional testing, such as radiographic inspection and ultrasonic inspection is available as well. 2M, Recommended Practices for Laser Beam Welding, Cutting, and Allied Processes. From a machine tool vendor's point of view these goals translate into different machine designs, such as welders for low to medium production or welders for mass production with short cycle times.

On the other hand, it offers a wide range of penetration depth, generally from 0.
