Circular saws are designed to make straight cuts on materials that are difficult to cut by hand. The saw’s size denotes the largest size blade that can be used with it. Most circular saws come with or can be equipped with a rip fence to maintain a uniform width of cut on long passes. Quality [...]

Metal Sales is one of the nation’s most respected manufacturers of quality metal roof and wall panels. The new lines [...]
WorldSteel – Crude steel production for the 66 countries reporting to the World Steel Association (worldsteel) was 124 million metric tons (mmt) in May. This is 29.1% higher than May 2009. China’s crude steel production for 2010 was 56.1 mmt, an increase of 20.7% compared to May 2009. Elsewhere in Asia, Japan produced 9.7 mmt [...]
Forge welding is said to be the oldest welding technique ever used by early blacksmiths, dating back to the Iron Age when ancient Egyptians and people from Eastern Mediterranean began to refine the craft of welding iron metals together. Also known as “fire welding,” this method attempts to fasten together two or more metal components [...]
When you buy sheetmetal from the steel supply shop, it comes coated with a rust inhibitor so that the product doesn’t rust before it gets sold. But if you try to weld to that surface, you’re going to get poor results, so you have to remove it first. Fortunately, it’s not very difficult to do. [...]
Increasing Productivity with a FCAW Wire Optimized for Your Application Ken Lee, Application Engineer, The Lincoln Electric Company If welding with a solid wire is satisfactory, why use a higher priced flux-cored wire? A flux-cored wire is optimized to obtain performance not possible with a solid wire. For many welding applications like vertical-up welding, flat [...]
The Croydon Group, Ltd., Rockford, IL In much the same way that the automatic transmission has simplified the process of driving, Gas Metal Arc Welding (GMAW) has simplified the process of welding. Of all welding methods, GMAW is said to be one of the easiest to learn and perform. The main reason is because the [...]
Sheet metal mark out or layout is the practice of putting dimensions on a piece of metal to show locations of cuts and bends that will be used to fabricate the final work piece. Sheet metal layout tools are needed to measure, mark dimensions, draw straight lines, find non-standard points and calculate round dimensions. Measuring [...]
Stainless steel alloys usually have a chromium content of a least 10%. Stainless steel base metals are grouped primarily into three classes depending on their crystal structure; austenitic (such as 302, 304, 308, 316, etc.), martensitic (such as 410, and 416), and ferritic (such as 409, and 430.). Austenitic grades are also available with a [...]
