Introduction Please find here our new Mid Month Bulletin that we offer with the purpose of providing useful online information easily accessible to our readers, either now or at some later date. Therefore may we suggest that you save or bookmark this page for your future reference. For any questions, comments or feedback please send us a message by e-mail. Don't use REPLY, use Contact Us. Note: References to articles or other documents are given here in one of two forms. If the links are "live" (usually underlined or otherwise highlighted) they are operated with a click of the mouse. If they are URL's (Uniform Resource Locator), which is the analogue of an address, they begin with "http://..." or "www.". These are not live and must be copied and pasted entirely into the browser (after having selected them with the mouse or otherwise). If they are long they may be displayed in two or more lines. In that case one has to care that the URL be copied completely in a single line without any space, and Enter.
A short note on PWHT was published (11) in Issue 09 of Practical Welding Letter for May 2004. Click on PWL#09 to see it. A note on Temper Bead was published (9.2) in the Short Items Issue 15 of Practical Welding Letter for November 2004. Click on PWL#015 to see it. After opening the following Resources, if the content looks interesting to you, save the files in a special folder you will have opened with a meaningful name, for your future reference.
