Joint Design For Welding: The Pros And Cons Of Groove Joints – Words With M O R N I A G R
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. These may include structural steels, hard-enable steels, stainless steels, titanium, zirconium, tungsten, molybdenum, beryllium, rhenium, tantalum and columbium. Weld Joint Design and Preparation 5. Scansonic FSO allows for improved depth of fusion while reducing flange length. Material Used: 316L Stainless Steel. Don't use bevelled edges and preferably use a whetstone for the careful removal of sharp slivers. Such a solution minimizes the time needed to generate the vacuum; nonvacuum electron beam welding machines (NVEBW). Laser welding uses a high-intensity beam of light to create a molten weld pool to fuse materials together. This type of configuration can also lend itself to finish machined details though the additional material used to locate the joint is sometimes removed after welding. Keep a gap of maximum 0. The width to penetration ratio upto 50, in steel welds, have reportedly been achieved. When alignment is critical, the self-fixtured butt joint in Figure 10 eliminates the need for elaborate tooling and extensive tack welding. Ultrasound cleaning or pickling is often used, depending on the type of material and application. 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.

Electron Beam Welding Working
Fusion and recrystallisation of refractory metals, on the other hand, raised the ductile-to-brittle transition temperature range to above the room temperature. Conventional Electron Beam Welding. Disadvantages of Electron Beam 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. There is no tooling above the joint that could interact with the weld beam as it comes into focus. Can reproduce precise welds at rapid weld speeds. Clean welds since EBW is done in a vacuum environment. According to John Rugh, LBW is commonly used for welding steel sheet metal components and machined components under 1/3" to 1/2" thick. There are several aspects to consider when designing joints for the electron beam welding process. Laser welding energy sources utilize either a continuous wave (CW) or pulsed output of photons.
Also, puddle welding is frequently used with locally-preplaced filler metal additions. The range of components to be welded typically includes a variety of designs for shaft assemblies as well as planet carriers. Now that the beam is able to be accurately placed into the seam, the ability to process a lap joint with high reliability is possible. The clamps are very close to the seam and apply pressure to ensure a minimal gap. There are advantages to be gained from specifying the simplest weld shapes since remote handling is an unavoidable feature of the electron beam welding process. A designer will be disposed towards the electron beam process when there is a requirement for EB's unique characteristics of a deep penetration weld and low total heat input.

Copper has superior thermal conductivity, which, for some applications, is a great attribute. A Virginia nuclear physics laboratory asked us to improve the quality of welds in vacuum chambers used in its' research equipment. The fixturing required before welding is of the lightest construction as no forces are involved in the electron beam process. Make sure the electron beam can fully access the weld location. Fusion Welding Comparison. Metal to metal contact provided by good quality copper chill bars is essential to control weld puddle contour. In most cases, a square butt joint design is utilized. Electron beam welding technology is proven safe and incredibly effective. 062″, electron beam welding may be useful if a less than full fillet is acceptable.
Flanges, for instance, are added to joints to increase structural strength and stability and can occur in a various array of automotive parts, including doors, windows, beams, and pillars. Lap Joint — Figure 18. Best of all, Sciaky's custom EB welding services are competitively priced and offer tremendous advantages over smaller job shops in terms of equipment and expertise. Both processes can be performed in a vacuum environment, protecting the weld pool from contamination against air molecules and improving the weld quality. Once melted, the reflectivity is reduced and the thermal conductance of the process progresses to achieve penetration. These features make it possible to focus the electron beam to diameters of 0. Electron beam welding principles and some aspects of the technology, which permits intricate and complex fabrications in various materials and material combinations, are discussed below. Some of these metals can be welded in air while others need inert atmosphere usually obtained by the use of argon or helium as the shielding gas. 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. Edge Joint & Tier Welds. The process requires highly skilled machine operators.
Electron Beam Welding Joint Design Pdf
The electron beam welding (EBW) and laser beam welding (LBW) processes are high-energy density welding processes that offer several possible advantages, including low welding heat input, high weld depth-to-width ratio, narrow heat-affected zone (HAZ), and reduced distortion. The easiest design for welding is to have the thinnest material on top and the thicker material on the bottom. Generally, LBW has simpler tooling requirements as well, and there are no physical constraints of a vacuum chamber. The allowable positional tolerance must be less than half the beam diameter to ensure that the laser beam interacts with both sides of the joint.
Axial and circumferential welds can be performed with a rotary tilt device that is mounted on top of the x-/y-table. A penetration weld is the commonly used trial weld technique to determine the welding parameters for a specific part thickness. Precipitation hardening stainless steels of the martensitic type have good weldability but require ageing to develop parent metal properties in the weld zone. 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. Ask one of our experts, or leave a comment in the space below. A fully penetrating weld as shown in figure 1 is often used when the assembly requires no post weld machining. Most standard NDT techniques can be used to check the integrity of electron beam welds; x-ray, PFD, ultrasonic and MFD. As with any rule, there are exceptions. 15, in such a way as to minimise the flow of atmospheric gases into the gun column.
Application Of Electron Beam Welding
Product Name: Vacuum Chamber. EB Welding is Affordable. Further improvements to weld quality can be achieved by using different weld patterns to eliminate undercuts and irregular penetrations. The energy density of the electron beam is around 1, 000 times more than that can be achieved from a traditional arc weld. Heat Treatment | Stress Relief.
This has particular advantage for surgical instruments, electronic components, sensor assemblies and many other precision devices. The kinetic energy of the electrons is converted to heat energy, which in turn is the driving force for fusion. Such fixturing can be automated with pneumatic clamps. Phases during weld solidification.
Electron Beam Welding Joint Design And Size
Welding in Vacuum is Ideal for Eliminating Weld Impurities. There are two variants or modes of the main process viz., medium vacuum EBW and non-vacuum EBW. Thus, it is employed for welding very critical components mainly of reactive metals. Again, the weld interface width determines the joint strength, therefore a defocused beam having a larger weld width will have an increased strength. The low power mode is used to produce extremely fine welds, which can be as small as 20µm.
By following these guidelines, a skilled EB welder can produce high quality, highly repeatable welds for applications using difficult-to-weld or dissimilar materials. The vacuum is only maintained in the small chamber. To achieve narrow weld and deep penetration, it is essential to focus the beam on the workpiece very accurately. Basically, the heat disperses quickly, either not heating the weld area enough, or overheating the entire part and causing it to melt and warp. The beam is introduced to the joint at a slight angle and can produce a "double fillet" effect on thin materials. Running the machine in keyhole mode can penetrate up to 300mm of steel and is known to create stable, good-quality welds for material thicknesses over 200mm. Most of the welds in EBW are made without filler metal.
