hello I'm building a TIG welder and have found the output from my stick welders to be not so good for aluminum(60 Hz on one). I've heard that high frequency AC is the way to do AL but am not sure what constitutes high. I do have a nice miller gas driven welder also that is maybe triple the frequency of my line driven one but still had issues with it. does anyone know of an actual # ? I may be able to build an inverting PWM supply eventually to do this but am not sure what I would need it to do. does anyone have any data that might help? any data/tips about aluminum would be appreciated, thanks in advance. FYI I do understand why AC works so much better on AL, what with the oxides that are always present.

NO... the TIG rods are uncoated and will not be able to create the shielding gas like coated rods would when used in an ARC welder. TIG (Tungsten Inert Gas) uses a shielding gas supplied from a tank, the aluminum rods are used as filler material and metled into the weld by the operator by using the arc from the tip as the heat source. Two different welding processes, hence the need for two different types of rods...

Yes, aluminum coils are suitable for roofing. Aluminum is a lightweight and durable material that is resistant to corrosion, making it an excellent choice for roofing applications. It is also highly reflective, which can help to reduce energy costs by keeping the building cooler. Additionally, aluminum coils are easy to install and maintain, making them a popular option for both residential and commercial roofing projects.

The minimum coil length of aluminum coils has certain limitations. These limitations are influenced by factors such as the manufacturing process, equipment capabilities, and the intended use of the coils. One limitation arises from the size and capacity of the manufacturing equipment. To ensure smooth operation and prevent damage during manufacturing, most coil production lines have a minimum length requirement. If the coil is too short, it may not be processed or handled properly by the equipment, resulting in production issues or defects. Another limitation is determined by the intended use of the coils. Certain applications may demand a minimum coil length to meet specific requirements or ensure optimal performance. For instance, industries like construction or automotive often utilize coils to create components or structures with precise length specifications. In such cases, the minimum coil length is determined by the end product's specifications. Furthermore, handling and transportation considerations also impact the determination of the minimum coil length. Coils that are too short might pose challenges in terms of handling, transportation, and storage, making them impractical or cost-inefficient. In conclusion, the minimum coil length of aluminum coils is constrained by manufacturing equipment capabilities, intended use, and practicality in terms of handling and transportation. These limitations guarantee efficient production processes, adherence to product specifications, and practicality within the overall supply chain.

The main difference between hot-rolled and cold-rolled aluminum coils lies in the production process. Hot-rolled aluminum coils are produced at high temperatures, which makes them more malleable and ductile. This process also results in a scaly surface finish. In contrast, cold-rolled aluminum coils are processed at lower temperatures, making them harder and more rigid. Cold-rolled coils have a smoother and more polished surface finish. Ultimately, the choice between hot-rolled and cold-rolled aluminum coils depends on the specific application and desired properties.

Yes, aluminum coils can be used in heat exchanger fins. Aluminum is a popular choice for heat exchangers due to its excellent thermal conductivity, lightweight nature, and corrosion resistance. The use of aluminum coils in heat exchanger fins allows for efficient transfer of heat between two fluids, making it an ideal material for this application. Additionally, aluminum coils can be easily formed into various fin shapes, providing flexibility in design and maximizing the surface area for heat transfer. Overall, aluminum coils are commonly used in heat exchanger fins to enhance heat transfer efficiency and improve the overall performance of the heat exchanger system.

The construction of railways heavily relies on aluminum coils, which possess unique properties and advantages. These coils are widely utilized in the manufacturing of railway tracks and train cars. One of the primary functions of aluminum coils in railway construction is their contribution to lightweighting. Aluminum, being a lightweight material, is ideal for reducing the overall weight of railway components. This is significant because lighter trains and tracks require less energy for operation, leading to improved fuel efficiency and reduced operating costs. Additionally, the decreased weight of aluminum components allows for increased payload capacity, enabling trains to carry more passengers or freight. Another crucial role of aluminum coils lies in their corrosion resistance. Railways are exposed to various environmental conditions, such as moisture, salt, and extreme temperatures. Aluminum possesses excellent corrosion resistance properties, making it highly durable and long-lasting even in harsh environments. This diminishes maintenance and replacement costs associated with rust and corrosion, ensuring the longevity and reliability of the railway infrastructure. Furthermore, aluminum coils offer excellent conductivity, which is essential for electrical and signaling systems in railways. Aluminum's high electrical conductivity facilitates efficient power transmission and distribution, enabling seamless communication between trains, signaling devices, and control systems. This contributes to the safety and efficiency of railway operations. Moreover, aluminum coils can be easily formed and fabricated into various shapes, providing flexibility in railway design and construction. This versatility allows for the production of customized railway components, such as curved tracks or aerodynamic train carriages, to meet specific project requirements. In conclusion, the indispensable role of aluminum coils in railway construction is attributed to their lightweight, corrosion-resistant, conductive, and versatile nature. Their incorporation into railway infrastructure results in various benefits, including enhanced fuel efficiency, reduced maintenance costs, improved safety, and the ability to design and construct innovative railway systems.
