Edge welding of dissimilar metals. The elimination of ambient gases, combined with the energy density of the electron beam, easily creates very strong and aesthetically pleasing welds. All values of this unique deflection parameter, such as frequency, pattern direction and size in x- and y-direction, can be programmed. Most grades of stainless steels can be easily welded with the electron beam and most importantly, the welds are corrosion resistant as the parent material. There are several aspects to consider when designing joints for the electron beam welding process. Typically, edge welding is done with direct fusion between the two materials (FIGURE 1). What Materials can be Welded with the EB?
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. Standards such as AMS2680, AMS2681B, AWSD17. Fillet Weld – Ex 1 & Ex 2 — Figure 19a & 19b. Figure 8 illustrates another variation of the self-fixtured joint that has the feature of a smooth bore for fluid systems that cannot tolerate flow restrictions. Have questions about joint design for laser welding or EB welding? Electron Beam Welding vs Laser Welding. Similarly, based upon the voltage used for accelerating the speed of electrons the guns are referred to as low voltage and high voltage types. Copper has superior thermal conductivity, which, for some applications, is a great attribute. Gears for these industries require exceptional quality in high volume and at a low cost. Therefore, fixturing is critical in these joint configurations to ensure high positional repeatability and minimal gap.
Standards Met: Customer supplied specifications. The addition of nickel shim may also be useful to achieve the desired ratio of austenite to ferrite for corrosion protection. As shown in Figure 19a and Figure 19b, the unique capability of the electron beam welding process can produce a fillet weld having a large depth to width ratio, resulting in a superior strength joint. Most penetration depths don't require filler material. Unlike EBW, LBW does not generate any X-rays and is easily manipulated with automation and robotics.
A lower power tacking pass with the electron beam helps to maintain alignment prior to a full penetration pass. An application that exploits the small electron beam cross-section is the joining of precision bellows of stainless steel to a tapered coupling. Butt welds do not require a chamfer for thicker pieces, T-joints can be welded from a single side with full strength, and lap welds can be welded through the top sheet or along the seam. Get your laser cutting quote in seconds. The butt joint configuration illustrated in Figure 2 is sometimes called a butt-lap joint and is used to provide alignment and filler material.
To further optimize productivity, the number of stations can be increased to 3 or 4 and the number of assemblies in each station may be also increased, depending on their size (Figure 10). "The weld quality is exceptional, the process is extremely efficient (typically 95%), all the process parameters are carefully controlled and the process fully automated. Generally, LBW has simpler tooling requirements as well, and there are no physical constraints of a vacuum chamber. However, EBW is used mainly for applications involving high precision and high production rate. Several different machine designs have been manufactured for the industry over the years, the simplest of which employs a vacuum chamber with a door in the front (Figure 12). The EBW equipment uses magnets to focus the electron beam. The client was seeking a way to minimize excess heat input, distortion, and variation in magnetic properties that result from conventional fusion welding.
Adaptation of technologies such as real-time seam tracking, gap bridging, beam oscillation, and integrated clamping to laser-related processes allows for them to be used in a more mainstream approach. As the name implies, it is a hole with a high vapor pressure in the middle that presses the molten material firmly against the side walls. Electron beam welders use this characteristic to electromagnetically focus and very precisely deflect the beam at speeds up to 10 kHz. The beam stays collimated until it hits a focus surface. Whenever possible, hollow areas should be vented to the outer surface of the part. The combination of deflection pattern and continuous adjustment of the beam power helps to mitigate this underfill thereby optimizing the joint quality to meet the specification.
Weld Dimensions: Joint Thickness:. Edge joints are generally used with sheet materials such as hermetically sealed cans, etc. The result is a deep, narrow, vapor-filled hole, or keyhole, surrounded by molten metal. Electron beam welding converts around 85% of the electrical input into usable power. One commonality of these electron beam welders is that all beam parameters and all mechanical axes are numerically controlled either by a PLC or a CNC. Due to technological, production-related and metallurgical requirements electron beam welding solutions include the following machines [19]: - –. It some cases this may need to be even tighter. Often a cover gas is used to minimize these effects. 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. 2M, Recommended Practices for Laser Beam Welding, Cutting, and Allied Processes. Although EBW is a high power density process yet the energy input per unit length is low as is evident from table 14. About the Publication. Essentially, the weld pool becomes a mirror reflecting energy away, again resulting in poor penetration or the over application of power, which can result in melting and distortion of the part.
Work-accelerated electrons are accelerated using the potential difference between the cathode and the workpiece.

Το δεύτερο ήταν ότι αυτός που μιλάει, που γεμίζει τον χώρο μιας συνάθροισης με λόγια, που τρέμει τη σιωπή, που τη θεωρεί ένα βήμα μετά την αγένεια κι ένα βήμα πριν από τη βλασφημία, έχει μυστικά, μυστικά που τα σκεπάζει με λόγια, όπως η γάτα τα κόπρανά της με χώμα· κι ότι εκείνος που σωπαίνει συχνά σωπαίνει λαλίστατος, αφού ξελαρυγγιάζεται να φωνάζει προς όλες τις κατευθύνσεις, σαν τον χαμένο στην έρημο, ακούστε τη σιωπή μου, είμαι σιωπηλός σαν την πέτρα.
