By Justin Obrien, eHow Contributor Arc welder at work. Welding is an important component of any metalwork job; the skill of welding can be highly valuable to learn because of the high cost to have repair and welding done. The cost of welding work ranges from $25-$50 an hour. Imaging doing it yourself to save [...]

By Derek Odom, eHow Contributor Welding stainless steel can be done with both stick and wire feed welders. If you are using a wire feed, or MIG welder, you must use gas on the project because stainless steel does not come in flux-cored form. Stainless steel resists rust and corrosion because of its high chromium [...]

Source: Adapted from The Procedure Handbook of Arc Welding. The Lincoln Electric Company, 1994. Although welding stainless steel may not be as difficult as welding aluminum, the metal does have its specific properties that vary from your more common steels. When MIG welding on stainless, you usually have three choices of transfer depending on your [...]

How to Weld Stainless Steel With Stick Welder By C.L. Rease, eHow Contributor    I want to do this! What’s This? Stick or ARC welding stainless steel requires the use of a welding rod that is compatible with the chemical makeup of the stainless steel you are welding. You can use a higher purity stainless [...]

How to Weld Steel By an eHow Contributor  I want to do this! What’s This? Steel is a metal alloy that primarily consists of iron and has a carbon content between 0.2 and 2.04 percent. It becomes harder and stronger but more brittle as the carbon increases, and other elements also affect its physical properties. [...]

 1. Introduction Common weld defects include: i. Lack of fusion ii. Lack of penetration or excess penetration iii. Porosity iv. Inclusions v. Cracking vi. Undercut vii. Lamellar tearing Any of these defects are potentially disastorous as they can all give rise to high stress intensities which may result in sudden unexpected failure below the design [...]
