It's frustrating as everyone will be quick to judge a battery for being poor, but no one will step up and call one out for being the best. Posted: 24 Sep 2011 13:50. so here is another question for you.
Was reading up on Li-Ion cells this weekend trying to decide if its worth it. Put another, you'll usually get the best results and smallest operating costs when you use two separate marine batteries. I'm using it on a teardrop style RV and was thinking of adding a 2nd battery to run my Air Conditioner off grid when we boondock. Description: Double steel construction. 67%, Northern Europe 15. Why did my SIX marine batteries (27DC2) die in less than one year. Fabrication: CNC Laser, Waterjet, Plasma, Welding & Fab. There is no direct conversion from reserve capacity to amp-hrs as they are measured very differently. None of this is to say that your battery will not do the job for you! Lithium is absolutely the future, just don't know how far in the future it will be to get the prices down, and trickle down the proper charging technology.

0%, Western Europe 20. Part of me says go big with quality and sit tight for 8-10 years, and part of me say go cheap and replace every 3-4 years. Similar to the one I purchase above but not sure how it needs to be wired and if it need any other components to make it work. Solar battery, ups battery, solar system, battery cabinet, 12v home appliances. When a cranking battery is subjected to continuous use, (e. g. trolling), it is subject to overheating and depletion of available capacity. This is generally false economy as the cheaper batteries will have a much shorter life (since they are not optimized for repeated discharge, may not provide the power you really need or just die prematurely - can be a bit like buying an expensive stereo but getting a great deal on cheap speakers. Lithium ion polyment battery, Portable power bank, 12V rechargeable lithium battery pack, cylindrical lithium battery pack, lifepo4 battery.

We fabricated clamping fixtures to secure the parts for welding using its internal machining capabilities. By lowering the beam power and either defocusing the beam and/or widening the beam by using deflection pattern. Whenever possible, hollow areas should be vented to the outer surface of the part. This paper provides a technical overview of the unique features of the electron beam welding process including several applications. The material, meanwhile, continues to melt. Salay Stannard, Materials Engineer for Joining Technologies, an East Granby, CT-based provider of laser cladding, electron beam and laser welding applications, said that CW lasers can achieve penetrations up to and exceeding 0. 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. Apart from the accelerating voltage, beam power, travel speed, gun to work distance, and the shielding gas are important process variables. 5 mm for thicker materials to ensure repeatable fusion that accounts for variation in production. Filler wire feeding equipment is usually similar to the one employed for gas tungsten arc welding though specific needs may necessitate the use of specially designed units for use in vacuum chambers. Conventional Electron Beam Welding. Welding Specification Certifications. Heat conduction laser welding is used for corner welds on the visible surfaces of device housings as well as other applications in electronics.
Elmer [45] pointed out that this could substantially vary from operator to operator and from machine to machine. Special shapes demanding deep penetration like the ones shown in Fig. The trapped air can cause porosity and expulsion of molten metal at the tie-in after a 360° weld. 005″ or as thick as 2″ or more. This welding technology is achieved by having only the electron beam gun inside a vacuum box while the workpiece itself remains outside of the vacuum chamber. DC power is used in the electron beam welding method with 5-30 volts for small equipment and 70-150 volts for large equipment. Laser beams require high welding speeds since it vaporises the base materials, creating fumes. Let's start with one of the strongest joint designs, the groove joint, and what makes it so "groovy": First, a quick definition: Groove joints or square groove joints are a type of butt joint, with two flat pieces parallel to each other and butted together with a 100% weld joining the two pieces. Creation of vacuum is therefore an essential requirement for an electron beam to materialise in the desired direction. The vacuum is only maintained in the small chamber. The absolute shortest cycle times can be achieved with the so-called nonvacuum electron beam welder which welds parts in atmospheric pressure. Figure 3 shows some typical laser welding joint configurations. Again, the weld interface width determines the joint strength, therefore a defocused beam having a larger weld width will have an increased strength. Light and medium duty planet carriers are made of low carbon steel sheet metal.
Top Scab — Figure 4. 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. These gases can react with the metal, creating oxides and other compounds that change the metallurgy of the weld pool and lead to impure welds. 062″, electron beam welding may be useful if a less than full fillet is acceptable. It is truly a high-quality process for joining high-quality materials. In these cases, a plug with a "top scab", as depicted in Figure 12, is recommended. 005″), this type of joint is sometimes more expedient to use, by virtue of simpler fixturing, than a square groove butt joint. However, when required level of vacuum is created the electron beam can travel fairly long distances and melt any known metal or ceramic. Making the weld strong and pure isn't an issue, and, fortunately, with a bit of well-engineered tooling and a degree of automation, these high quality welds can be achieved with very short cycle times and low cost. Butt welding requires accuracy and process repeatability but can achieve strong welds with minimal heat input. With CW systems, the laser beam is always on during the welding process.
The medium vacuum process retains most of the advantages of high vacuum welding and with improved production capability. Typical products produced by this process include nuclear fuel elements, special alloy jet engine components, pressure vessels for rocket propulsion systems and hermetically sealed vacuum devices like sealing of transistors, micro-switches, etc. We electron beam welded 4 plates together to form a box section. There are two variants or modes of the main process viz., medium vacuum EBW and non-vacuum EBW. Modified Integral Backup — Figure 3. Such applications are the main requirement of nuclear, aircraft, aero-space, and electronic industries. Capabilities Applied/Processes: Weld Joint Design Consultation. So far as electron beam welding is concerned, high chromium content stainless steels, noted for their corrosion and temperature resistance, can be briefly categorised as the below. The use of this design assumes accessibility to both surfaces for machining and inspection purposes. Provide better overall weld properties compared to arc welding. Don't use bevelled edges and preferably use a whetstone for the careful removal of sharp slivers. We have the capability to weld large assemblies up to 24 feet in length and 92 inches in diameter, as well as tiny parts that fit in the palm of your hand. Manufacturing cost and quality are key goals to consider in the fabrication of components.
Although this joining method produced a joint of adequate strength, the post-weld machining, grinding and heat treatment operations were expensive and time consuming. The Scansonic RLWA (Remote Laser Welding - Adaptive), which utilizes a 500mm standoff and offers real-time seam finding and tracking via its process controls located internal to the head, now has an option called "gap bridging. " The specification of these segmented welds typically does not allow for substantial underfill of material either at the beginning or at the end of the joint (Figure 7). Generally, it is the most practical and most efficient configuration to use. This is unique to the electron beam welding process, using the keyhole welding mode. 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. Aerospace Control and Quality Standards. Galvo mirrors—high-speed mirrors inside the welding optic—position the beam for welding and provide all the motion for the weld path. Such fixturing can be automated with pneumatic clamps.
Lap welding requires less robust fixturing. The joint tolerances must provide a maximum gap of 0, 1mm. If minimal distortion is critical, the weld should only partially penetrate the bottom sheet. What if it was possible to reliably process flanges, as well as drastically reduce flange length and still maintain a robust manufacturing process? Extreme precaution is required from radiation. The intensity of electron beams is 100-1000 times higher than arc welding, allowing deep penetration and narrow heat-affected zones. To avoid under fill or incomplete fusion, joints must be carefully prepared to achieve good fit-up and alignment.
A tight slip fit to an interference fit is recommended for proper welding. EBW - Higher Purity, Deeper Weld Penetration. Recent machine developments make it possible even to go up to 200 kHz. The molten metal from the forward portion of the vapour hole flows around its periphery and solidifies at the rear to form weld metal as the beam moves forward along the weld line. This results in the formation of plasma, which puts energy into the workpiece as well. Unlike EBW, LBW does not generate any X-rays and is easily manipulated with automation and robotics. 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. Most of the welds in EBW are made without filler metal. The allowable gap typically is 10% of the top material thickness. With gap bridging algorithms predefined within the system controls of the RLWA, the optic has the ability via the seam tracking package to identify gaps in the joint and automatically adjust various conditions to process the joint.
Variants of EBW Process: The features 80 far discussed pertain mainly to the high vacuum type EBW guns. This joint preparation can be expensive, but is used in fatigue-critical applications where the notch effect of non-fused material and a change in cross-section is minimized. Consider the proximity of components that might be affected by temperature. This type of joint is especially useful in areas where the parts are used, disassembled, refurbished, and resealed by welding. For especially critical welds, a single large fixture, designed with the weld path machined out, can ensure ideal part fit-up. 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).
Therefore, these parameters are tightly controlled in the welding process.
