In What is a Low-Carb Diet?, I outline three approaches to low-carb eating, only one of which focuses on ketosis as a goal throughout the diet. Diets such as the Atkins Diet start out as a very low-carb ketogenic diet, but as people add carbohydrate, many or most will be eating too much carbohydrate to be in ketosis.
At the core of any custom motorcycle project is the welding process used to join the tubing that makes up the bike's frame. This article will discuss how both MIG and TIG welding fit into this process and how even a novice welder can get started. (As seen in the Welding Journal, October 2005)
FSW has been used to weld many softer materials (aluminum, copper, magnesium, etc.) for over a decade, and has more recently shown promise for welding harder metal alloys (steels, titanium, and nickel). Shown in Figure 4 is a typical friction stir weld made on Â¾-in. (19-mm) thick high-strength steel. Research is currently underway to evaluate tool life and weld properties for FSW of steel. EWI has been working to advance the friction welding processes for nearly 25 years.
