The design of the clamping unit allows for reaching into openings or structures where flanges might be present, and its fast open-and-close clamping mechanism (200ms) provides a good foundation for high-volume applications. Lap welds must be wider to increase their strength. One of these joining methods is laser welding. With all of laser welding's process considerations also come myriad opportunities. 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.
These may include structural steels, hard-enable steels, stainless steels, titanium, zirconium, tungsten, molybdenum, beryllium, rhenium, tantalum and columbium. Although the additional material is located on the root surface, it will provide a positive top bead reinforcement. Laser edge welding of seams. EB welding is a process that can be used to produce high quality welds on a range of dissimilar or difficult materials. Joint and fixture design also plays a role. Proponents of laser beam welding (LBW) and electron beam (EBW) welding each pronounce the singular praises of their favored technology, but often the best solution for a customer is to use both technologies together. Then the beam narrows into an hourglass shape until it becomes in focus at its smallest point. Technical problems arise from lack of experience of electron beam welding as a process. Adaptive remote welding. What Is Electron Beam Welding? Whether it's creating high temperature exhaust nozzles for rockets or jet aircraft, or joining cutting-edge 3D printed parts, EB welding has advantages that other welding processes simply don't. Weld Dimensions: Joint Thickness:. What if it was possible to reliably process flanges, as well as drastically reduce flange length and still maintain a robust manufacturing process?
The nuclear industry was the first to adopt electron beam welding of stainless steels on a large scale to exploit the properties of a small heat-affected zone, low incidence of defects, and near parent metal strength, to fabricate fuel and coolant containers of all sizes. Shorter cycle times translate to cost advantages without sacrificing quality. This joint design may be limited by access to NDT techniques. It centers on improvements to the electromagnetic focus and deflection system to shorten their response times. This parameter, unique to the eb process, deflects the beam at a rate of a few hundred Hertz in a pattern, such as circle or arrow head (Figure 5). Laser beams require high welding speeds since it vaporises the base materials, creating fumes.
But that high thermal conductivity also makes copper notoriously difficult to weld. Figure 4 shows a rigid fixturing for a corner weld. 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. Following are the top five reasons why electron beam welding is still as cutting edge as it was almost 60 years ago. Scribe lines are used to locate the internal weld joint. Only use non-magnetic materials, or materials that can be properly demagnetised.
5, is achieved by expending the beam energy. Therefore, fixturing is critical in these joint configurations to ensure high positional repeatability and minimal gap. The joint tolerances must provide a maximum gap of 0, 1mm. 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. The addition of the oscillation feature enables a "remelting" of the pool, thus allowing the zinc to be brought to the surface and not remain entrapped in the weld. Weld Characteristics and Quality 6. Compared to butt welding, lap welding has a larger process window, mainly because penetration depth is more flexible. Also, puddle welding is frequently used with locally-preplaced filler metal additions. Energy is thus given less time to dissipate into the interior of the workpiece.
So, they may require nickel addition to the fusion zone and/or pre or post-weld heat treatment to achieve acceptable joints. Modulation characteristics for the gap-bridging algorithm in the Scansonic RLWA. Aerospace Control and Quality Standards. We consulted with the customer to design an electron beam-specific weld joint that optimized virtual leak performance at ultra-high vacuum.
Based on the ability to control the beam location relative to the joint and utilize oscillation, it provides a melt pool that "floats" on the workpiece (FIGURE 4). LBW - Simpler Tooling, Shorter Cycle Times. For example, gold, silver, copper and aluminum require more intense energy input. 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. This produces a deep, narrow weld with a uniform internal structure. 125 mm; however aluminium alloys can tolerate somewhat larger gaps than steels.
Slower weld travel speeds produce a shallower temperature gradient in the HAZ and are beneficial towards reducing liquation cracking susceptibility. If the focus position shifts outside this area, expect the process results to change. Pre- or Post-Weld Machining. If components are of high value, made of a material that would benefit from the vacuum environment such as titanium and nickel alloys, the welds are deeper than 1/3" to 1/2", or if the laser beam has difficulty coupling with the material being welded such as aluminum alloys, EB welding is often the process of choice over laser welding. The low power mode is used to produce extremely fine welds, which can be as small as 20µm. Tack welds are made at less than the power needed for full penetration (20% to 40%).
