Mid March Bulletin

Introduction

[Note: DON'T USE REPLY to send us your messages!
Use Contact Us instead.]

On the arguments of this Issue you may see also the following Website pages:
Welding Software.
Welding Cost Estimate.

Previous Issues of Practical Welding Letter are available at the Index of Past Issues of PWL, while the Titles of important Articles published there are in the page on Welding Topics.

The Index of all previous Issues of the Mid Month Bulletins can be found in the page of Welding Resources.

The subject of this Bulletin is quite important for many welders, therefore it is recommended to bookmark this page or keep its reference handy for further use. The systematic collection of information on previous jobs can be useful for estimating cost and time frame for future applications.

Everyone involved can easily collect in a simple spreadsheet all important data for all current jobs, including Welding Procedure Specifications (WPS) with all parameters, and at least estimates, if not precise calculations, of consumable consumption and costs.

The addresses reported hereafter were live and correct at the time of their publication. There is no guarantee that they will always be so, because they are administered by the sources themselves and are under their control.

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.

If the information is important to you as we hope, you may save the selected pages in a suitable folder on your Computer for easy reference. You are welcome to forward this page to those of your friends who may profit of this information.

Ed Craig from

reminded me that:
"The most simple yet comprehensive weld cost calculations available for decades have been in my process control training resources,
Ed"
