Technical problems arise from lack of experience of electron beam welding as a process. This produces a deep, narrow weld with a uniform internal structure. Prevent trapped cavities. High thermal conductivity creates challenges for heat conduction-based welding methods, such as MIG and TIG. However, in lieu of clamping, this offering comes equipped with "gap bridging" technology. Variants of EBW Process: The features 80 far discussed pertain mainly to the high vacuum type EBW guns. Self-Fixtured Bar Joint — Figure 10. The NVEBW machines are provided with high-efficiency pumps and special electron beam discharge orifices to ensure the highest vacuum decrease gradient between the electron gun and atmosphere.
Electron Beam Welding Applications
If an actual value exceeds the programmed tolerance of the set value, the machine will either stop or notify the operator of this fact. Electron beam welding processes are usually carried out in a vacuum, yet there are also nonvacuum welding machines available. The client was seeking a way to minimize excess heat input, distortion, and variation in magnetic properties that result from conventional fusion welding. The backside of the weld is also a problem because it is as prone to these problems as the front. Edge Joint Ex 1 & Ex 2 — Figure 16a & 16b. It is beyond the scope of this paper to detail the weldability of various metals; therefore, the following examples will focus on certain production applications. Electron Beam Engineering, Inc. is a leading specialist in high precision electron beam welding and laser welding, serving multiple industries including aerospace, automotive, defense, communications, electronics, jewelry, medical, oil and gas exploration, semi-conductors, sensors, transportation and commercial uses. Applications and Materials. 11, include butt, comer, lap, edge and Tee types or their modifications to suit particular applications, using square edge preparation. Welding of low melting alloys, like aluminum or magnesium, may initially be a challenge as the high beam power concentration easily can overheat the material possibly resulting in porosity in the weld, rough top beads and splatters. Examples are aerospace welding of titanium and its alloys, and many refractory metals such as tungsten, niobium, rhenium and tantalum.
Electron Beam Welding Joint Design And Procedure
These laser beams may be delivered directly to the part via classical hard-optics, or through a highly flexible fiber optic cable capable of delivering the laser energy to distant workstations. The use of 4000 series aluminum filler wire changes the metallurgy and prevents cracking. Tier Joint — Figure 17. Process Characteristics 4. Electron beam welding (EBW) uses a high-velocity beam of electrons to melt and fuse metals together. The tubular fabrication in austenitic stainless steel type 304L shown above contains three pieces – a hexagonal base welded to a tube with the tube itself capped by a nosepiece. Inversely, lap welding requires less accurate fixturing and has a larger process window but requires more heat input to achieve stronger welds. Acetone is a preferred solvent for cleaning the components for EBW; however acetone being highly inflammable needs to be handled very carefully. Have questions about joint design for laser welding or EB welding? Generally no preheat is required even for welding, high conductivity materials, with EBW. Nevertheless, lap welding has many benefits.
Electron Beam Welding Joint Design And Installation
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. In heat conduction welding, the laser beam melts the mating parts along a common joint, and the molten materials flow together and solidify to form the weld. The materials that can be welded by non-vacuum EBW system include carbon, low alloy, and stainless steels, high temperature alloys, refractory alloys as well as copper and aluminium alloys. Typically, metal additive manufacturing relies on melting a powdered material into a solid. As electron beam welding technology is highly automated and delivers a clean result with repeatable accuracy and minimal distortion, there is no need for post-weld machining. Or agitation of the weld pool by weaving the beam may provide the time necessary to help gases escape the weld pool and reduce porosity. However, these advantages are gained at the expense of low weld depth to width ratios, reduced weld penetration and small gun-to-work distances. Compared to butt welding, lap welding has a larger process window, mainly because penetration depth is more flexible. This variant is ideally suited for mass production tasks, for example, gears can be successfully welded to shafts in their final machined condition without involving any subsequent finishing operation while maintaining close tolerances.
Electron Beam Welding Joint Design Example
Solid Bar Butt Joint — Figure 9. The electron beam travels through the abutting surfaces, and the joint surfaces are then progressively fused – creating a weld. Slower weld travel speeds produce a shallower temperature gradient in the HAZ and are beneficial towards reducing liquation cracking susceptibility. This results in a very concentrated (approx. The first practical electron beam welding machine was put into use in 1958. If applications require low heat inputs and either low power or high processing speeds, partial-penetration joints can be ideal. A lower power tacking pass with the electron beam helps to maintain alignment prior to a full penetration pass. Whether your requirements call for the development of a prototype part or fabrication services for large volume production, Sciaky has the right solution to meet your needs. Conduction type welds can be used e. g. for cosmetic paths to smoothen the top bead of key hole welds in a subsequent operation (Figure 3). Utilization of tools such as optical seam tracking, integrated clamping, beam oscillation, and gap-bridging algorithms enable the user to further gain the advantages seen from laser welding (e. g., processing speeds, low thermal input, etc. ) 010" will require larger than desired beam diameters and can risk "missed joint" type lack of fusion defects. Our machines are built and manufactured at our Cambridge Headquarters. Joint Access and Postprocessing.
Electron Beam Welding Joint Design Creation
Adjustments to these values can significantly enhance the stability of key holes in most welding applications. 1mm) is typically mandatory to ensure that the zinc has a place to escape as it vaporizes at a temperature more than half that of the base material. This nailhead type of penetration is achieved through a phenomenon called key-holing. But that high thermal conductivity also makes copper notoriously difficult to weld. Plug Weld with Top Scab — Figure 12. The precise control of both the diameter of the electron beam and the travel speed allows materials from 0.
Electron Beam Welding Working
Sometimes filler metal may be added to achieve the desired physical or metallurgical characteristics of the weld metal; the characteristics so controlled may include ductility, tensile strength, hardness and resistance to cracking. As with any rule, there are exceptions. 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. Larger fibers have a larger depth of focus compared to smaller fiber diameters. This is critical to get the same power density to ensure repeatable results. This machine control can be considered the most basic quality control system; of course, the numeric control offers network connections for more elaborate quality control functions and data acquisition. We'll be taking a look at the different types of joints and briefly discussing the pros and cons of each, especially in relation to laser and electron beam (EB) welding. Tack welding with the electron beam is generally useful as a fixturing aid. The fixturing method has higher tooling costs but is also very robust and repeatable. NDI—Leak checking, Die Penetrant inspection, Laboratory Testing and Demonstration Capabilities. The weld depth may exceed 10 times the weld width. Widely accepted across many industries, EBW permits the welding of refractory and dissimilar metals that are typically unsuited for other methods. 3D printed materials are particularly well suited to EB welding. Because it is a noncontact process, welding in holes and in tight spaces is possible if the beam width as it comes into focus is considered.
EB Welding is Affordable. This transformation is stable in the high 90% range for all metals regardless of whether the electrons hit the surface at a perpendicular or shallow angle. The product's ability to accommodate variation in real time enables a stability that has typically hampered similar process approaches in the past. By defocusing the beam, the fillet weld may be enlarged and will present a smoother surface. As noted, the laser's high power density results in small heat-affected zones and ensures that critical components are unharmed. For copper, EB welding is often the most feasible option. The electron beam focus is typically achieved by controlling the accelerating voltage, beam current, focus coil current, vacuum levels in the gun and in the chamber, and the working distance. However, the main necessity for operating under vacuum is to control the electron beam precisely. Metal to metal contact provided by good quality copper chill bars is essential to control weld puddle contour.
Lap welding requires less robust fixturing. Can the joint be designed as self-locating or will a fixture be required? With careful control, an electron beam welder can join parts with minimal porosity issues. We have found these visualizations help when defining a new job. Ultra-high energy density enables deep penetration and high aspect ratios, while a vacuum environment ensures an atmospheric gas contamination free weld that is critical for metals such as titanium, niobium, refractory metals and nickel-based super-alloys.
Make sure the electron beam can fully access the weld location. EB Welding Has the Deepest Penetration with the Smallest Heat Affected Zone. EB welding can also be a very cost effective joining technology. However, it is important to note the metallurgical factors to attain satisfactory quality. An added benefit is that the welding speed is often 10-50 times faster than an arc weld which minimizes heat accumulation and produces less distortion and a smaller heat affected zone (HAZ).
The angle should be only as large as necessary to assure no scarfing, but not so large as to exaggerate the tendency to produce a lack of root fusion. The indexing table welder design was established as a reliable machine tool for high-volume production of assemblies several decades ago. With all of laser welding's process considerations also come myriad opportunities. 005 to 2 inches (although much higher depth can be achieved for certain materials) when using a filler material with the latter, making it stand out compared to common welding techniques like MIG, TIG, and stick welding.
The dissipating vapor exerts pressure on the molten metal and partially displaces it.
