Types of electron beam welding machines due to working chamber design are shown in Fig. Larger fibers have a larger depth of focus compared to smaller fiber diameters. Some martensitic steels have high carbon content, and this is detrimental to good welding performance. Fusion and recrystallisation of refractory metals, on the other hand, raised the ductile-to-brittle transition temperature range to above the room temperature.
The following examples illustrate the remarkable versatility of the electron beam welding process in a range of weld penetrations and material combinations. Assembly and Finish Machining. The addition of small amount of aluminium wire or shim, for example, can result in the production of killed steel and that reduces porosity. Due to enhanced presence of air in medium vacuum (100 ppm) mode the process is less satisfactory than high vacuum welding for reactive metals. Heat conduction laser welding is used for corner welds on the visible surfaces of device housings as well as other applications in electronics. Joining Technologies, Inc. 17 Connecticut South Drive. There are materials where it is advantageous to use filler metals, e. avoiding weld cracking in 6000 series aluminum. It is often used in unrestrained parts to prevent opening-up of the seam as full penetration welding progresses. The gap between the faying surfaces should be as small as possible with a maximum of 0. It's also a great option for welding metals with different melting points and thermal conductivities. Laser edge welding of seams.
Edge Joint & Tier Welds. 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. Electron Beam Welding vs Laser Welding. Although filler metal is not normally added to the weld pool, it can be added via bare wire. Narrow welds for a limited heat input minimize and keep the amount of distortion at a technically acceptable level and are therefore critical to this application. These electrons are accelerated using a high voltage, typically in the range of 30kV to 150kV and with the aid of a focus (convergence) coil and a deflection coil, the electrons can be formed into a narrow convergent beam and accurately positioned on the work piece. Will the design incorporate finish sized details or parts that require post weld machining? In the majority of laser welding applications, zero gap is the ideal condition to ensure proper fusion between the upper and lower sheets. Solutions to specific weld challenges using the EB process will be shown. For example, what spot size is needed for a given process? The dissipating vapor exerts pressure on the molten metal and partially displaces it.
In every industry, products are being designed, redesigned, or reevaluated for better materials or functionality. However, the EB welding process also has proven flexibility, adapting with the times such that it is an important part of even the most modern of manufacturing technologies. 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. It is, therefore, imperative to clean the joint thoroughly before fit-up and alignment. An application that exploits the small electron beam cross-section is the joining of precision bellows of stainless steel to a tapered coupling. The EB in non-vacuum welding is brought out of the vacuum system through a series of evacuated chambers with small apertures, as shown in Fig. This can be accomplished by scoring the joint faying plane with a scribe line(s) 0. The process laboratory occupies about 4, 000 square feet within the service facility. If the weld metal area is to be increased, as in the case of joining thin pipes, the edges may be scarfed. This required the use of reactive (like titanium and zirconium) and refractory (like tungsten, molybdenum and tantalum) metals.
Since the majority of applications need axial or circumferential welds, multiple part holders should be used whenever possible in order to make the process more cost effective. Most flanges, however, are designed to enable efficient welding with current resistance welding and laser optic offerings. The main components of electron beam welding equipment are the following: Electron Gun. The modification to the integral backup in Figure 3 is sometimes used for crack sensitive materials. Such a solution minimizes the time needed to generate the vacuum; nonvacuum electron beam welding machines (NVEBW). Also, there is a probability of evaporation of high vapour pressure metals during welding. Sensitive to faying surface conditions. Electrons are the basic particles of atoms that are negatively charged, extremely lightweight and are the transporters of electrical energy. There are two types of electron guns. Recently, there has been some work done to develop lasers that can approach the penetration of an electron beam. In this process, the laser beam not only melts the metal but also produces vapor. On top of that, EBW works at a rapid rate, making it one of the fastest processes in assembly welding.
Joint Considerations. For more information on our capabilities or if you have a project that you'd like to quote, fill out the form to the right, give us a call at (413) 734-4544, or email us at! A fully penetrating weld as shown in figure 1 is often used when the assembly requires no post weld machining. The intensity of electron beams is 100-1000 times higher than arc welding, allowing deep penetration and narrow heat-affected zones. 5", while pulsed lasers typically achieve only 0. Butt welding requires high positional accuracy. Filler material is not typically used to join the majority of components hence the metallurgy does not change. An example of the cleaning action for the weld can be seen in the case of zero-gap welding of galvanized material. An area where EBW is being increasingly utilized is the manufacture of turbochargers for diesel engines, which are growing in popularity due to their potential to greatly improve engine efficiency.
Joint and fixture design also plays a role. Electron beam welding processes are usually carried out in a vacuum, yet there are also nonvacuum welding machines available. In the case that a lap fillet is the functional joint that needs to be processed, similar issues are seen here as well regarding joint location and required overlap. Low to medium carbon micro-alloyed steels are typically used for manual transmission gear components in the automotive industry (Figure 6). Contact us to know more about our EB welding capability, and how we can help you achieve a high-quality product using EB welding. It centers on improvements to the electromagnetic focus and deflection system to shorten their response times. Most materials will lose some of their mechanical properties after welding so an assessment of strength requirements will need to be made. 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.
The higher the accelerating voltage the further the beam travels in gas at atmospheric pressure and voltages of 150 to 175 KV are used. Gears for these industries require exceptional quality in high volume and at a low cost. When fast moving electrons hit a metal surface they are decelerated which transforms the kinetic energy of each individual electron in the beam into thermal energy in the component.
The idea presented in FIGURE 2 depicts a method of gaining improved depth of fusion while reducing flange length by more than half of current standards. Pretty groovy, right? A major advantage of the medium vacuum EBW is that the requirement for vacuum pumping are considerably reduced resulting in high gains in commercial and economic terms. Simply confirm your details using the form provided to get your copy of our BEST PRACTICE GUIDE.
With all of laser welding's process considerations also come myriad opportunities. Some of the industries benefitting from this include aerospace, automotive, medical, nuclear, oil and gas. This results in a narrow heat-affected zone and less fatigue debit to the component. 005″), this type of joint is sometimes more expedient to use, by virtue of simpler fixturing, than a square groove butt joint. It is better to attain 60-70% penetration to minimize porosity formation. If welding through the top sheet (3 in Figure 2), the laser beam must penetrate through the top sheet and into the bottom sheet, and all that energy spent penetrating the top sheet doesn't add any weld strength.
This requires more energy input, achieved either through a larger spot size or by oscillation with a smaller spot size. Inspection Techniques. NDI—Leak checking, Die Penetrant inspection, Laboratory Testing and Demonstration Capabilities. It can withstand stress better than any other type of joint design. This is not usually a problem with joint thicknesses up to 0. LBW - Simpler Tooling, Shorter Cycle Times. Small heat input, low distortion. Lap Joint — Figure 18.
