Guide to Industrial Aluminum Welding — The Basics
2020年8月24日 · Store aluminum pieces vertically to minimize condensation and absorption of water contamination between layers. Bring filler and base metals into the welding area 24 hours before welding when possible. This allows them to reach room temperature and minimize condensation. Keep filler metals covered prior to welding.
Ron Covell's Expert Advice When TIG Welding Aluminum
2020年4月8日 · Clean everything scrupulously. TIG welding aluminum requires that everything be squeaky clean, and this is particularly important with aluminum. Any trace of oil can cause porosity and may inhibit the flow of molten metal. I recommend getting in the habit of using a degreaser, since even the invisible oil from your hands can cause problems.

What You Need To Know About Cleaning and Preparing …
2012年11月6日 · Removing the natural oxidation layer that occurs with aluminum is also an important step during pre-weld cleaning. Suitable preparation prior to welding is important — especially when fabrications are necessary to meet the weld quality requirements of industry codes, such as AWS D1.2 that governs the structural welding of aluminum.
Factors for Selecting the Right Stick Electrode | MillerWelds
2009年6月26日 · There are several factors to consider in welding rod selection: Base metal properties. Tensile strength. Welding current. Base metal thickness, shape and joint fit-up. Welding position. Specification and service conditions. Environmental job conditions.
How to Choose the Best Tungsten for AC TIG Welding
2007年4月1日 · AC vs. DC TIG welding. An AC TIG inverter is ideal for welding aluminum because it allows welders to fine-tune the weld bead profile by controlling arc cone shape and arc force through increased balance and frequency control. This lets operators change the shape and force of the welding current from a wide fan to a more focused stream.
TIG Weld Setting Calculator | MillerWelds
Use water-cooled torch when welding with more than 200 amps. Butt Weld (V-Groove) Bevel must have 60 degree included angle. 3/16 Root face. AC TIG is generally used to weld aluminum and magnesium materials. For the best appearance, highest quality and leak free welds on aluminum, AC TIG welding is the process of choice.
8 Questions About Stick Welding Rods Answered | MillerWelds
2007年12月1日 · 1. What are the most common stick electrodes? Hundreds, if not thousands, of stick electrodes exist. The most popular fall into the American Welding Society (AWS) A5.1 Specification for Carbon Steel Electrodes for Shielded Metal Arc Welding. These include the E6010, E6011, E6012, E6013, E7014, E7024 and E7018 electrodes.
All About Tungsten in TIG Welding: Types, Selection and Use
2022年10月5日 · In the early days of TIG welding there were only two types of tungsten that were commonly used. Pure tungsten was favored for aluminum and magnesium, and 2% thoriated tungsten was used for everything else. While these worked well for generations, research and development led to a broad range of tungsten electrodes, each with unique properties.
The History of Welding | MillerWelds
2020年4月21日 · Historians credit Edmund Davy of England with the discovery of acetylene in 1836. Sir Humphry Davy produced an arc between two carbon electrodes using a battery in 1800. In the mid-19th century, the electric generator was invented and arc lighting became popular. Gas welding and cutting developed during the late 1800s.
