Edge Joint Ex 1 & Ex 2 — Figure 16a & 16b. It centers on improvements to the electromagnetic focus and deflection system to shorten their response times. A challenge greater than the sheet metal design is posed by joint segments with varying thicknesses that require a change of power not only at the beginning and the end of the joint but also in between. Can the joint be accessed by a beam of electrons? Filler material is not typically used to join the majority of components hence the metallurgy does not change. Further advantages are; minimal distortion, a very narrow HAZ (heat affected zone) and as the welding normally takes place within a vacuum environment the risk of hydrogen contamination of the weld is minimised. The end result is one where the laser spot position relative to the seam is controlled in a dynamic nature, not simply shooting to a programmed point in space. If the configuration includes a hollow area, such as the center tap, there will be a problem with trapped air, especially when tight or press fit joint is used. With 60-years of process know-how in providing turn-key solutions, we can find the right solution for your application. What Is Electron Beam Welding? Thus, it is employed for welding very critical components mainly of reactive metals. Elmer [45] pointed out that this could substantially vary from operator to operator and from machine to machine.
Electron Beam Welding System
When alignment is critical, the self-fixtured butt joint in Figure 10 eliminates the need for elaborate tooling and extensive tack welding. Laser welding is perhaps an option, but weld penetration is limited by not only thermal conductivity, but also reflectivity. Use guide edges to line up pipes for example, to simplify clamping. 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. 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. Penetration in EBW is also inversely proportional to the melting point and thermal conductivity and proportional to the square root of the thermal diffusivity of the material being welded. One of the biggest challenges in welding involves minimizing the impact of the molten metal's interaction with ambient gases. 13 shows types of joints which are unique to electron beam welding; welding in a recess, welding a T-joint with a spike and welding simultaneous multiple joints. Such a solution minimizes the time needed to generate the vacuum; nonvacuum electron beam welding machines (NVEBW). Figure 3 shows a typical medium-size chamber on a CVE electron beam welding machine. Joint Access and Postprocessing. When welding this type of "scab" joint, as in any blind weld, the use of scribe lines is recommended to aid in the optical tracking of the joint.
Two Applications Of Electron Beam Welding
This case study explores electron beam (EB) welding of stainless steels, including weld characteristics, joint design considerations, and examples of welded stainless steel components. What Materials can be Welded with the EB? 109 × 10-28 gm; so it cannot travel any significant distance in air or other gases. This is accomplished through an orifice which is large enough for the beam to pass but does not allow significant back diffusion of gases from chamber to the gun column. Gaps measuring half the upper material thickness or less can easily be addressed with both steel and aluminum, while further studies show abilities beyond that in certain situations (FIGURE 6).
The clamps are very close to the seam and apply pressure to ensure a minimal gap. 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. Quality Procedures and Manuals, detailed operation sheets, Approved EB weld schedules with configuration controls. Usually no added filler material is required or used, and post-weld distortion is minimal. That also ensures self aligning. Slower weld travel speeds produce a shallower temperature gradient in the HAZ and are beneficial towards reducing liquation cracking susceptibility. Having both laser and electron beam technologies in a single facility can streamline the manufacturing process when a component's design incorporates multiple weld joints separately tailored for one process or the other. Prevent trapped cavities. Most penetration depths don't require filler material. The exit end of the nozzle is an assembly of Inconel 625 and Hastelloy, and the support stem is type 347 stainless steel. Generated from some form of medium, the light exits the laser source and begins to diverge.
