The subject of this Bulletin_78 was briefly dealt with before.It was in a note published (2) in Issue 76 of Practical Welding Letter for December 2009. Click on PWL#076 to see it.
For years Ed Craig, the renowned world expert on Gas Metal Arc Welding, insisted that perfect results were achievable with standard equipment (at reasonable cost), provided weld expertise was available.
Mid Month Bulletin No.78
15 October 2012
Bulletin_78 - Resources on Pulsed Arc Welding for exotic metals, for stainless steel, for savings and quality, for reducing heat input and warping, for thin aluminum applications, for reducing residual stresses, parameter optimization, experimental research, considerations for adopting pulsed arc welding, Optimization of Experimental Conditions and much more...
Jumping unprepared in adopting new "bells and whistles" equipment was held as a sure recipe for frustration.
It is refreshing to find out (see the third resource hereafter) that his mind is now appeased.
Undoubtedly this is due to the progress in electronic technology and to the carefully selected instances where, in his opinion, controlled waveform provides real advantages.
Like most of technological switch overs, also in this case thorough understanding, accurate preparation and a suitable learning curve should be dedicated to develop adequate schedules with measurable gains relative to the old way of welding.
Readers with experience in successful adapting pulsed arc to their regular production are urged to write a short note (to be published here) with their suggestions to our public, for improving performances.
Some of the published online resources referred here in Bulletin_78 can be downloaded at no cost. To benefit from the information there are no shortcuts: one should dedicate to learning the necessary time.
The references published in this Bulletin_78 are selected to provide useful knowledge to our readers.
Some of the sources are commercial companies, presenting their wares together with technical recommendations. No endorsement or recommendations of such offers is intended. Readers should check if such information meets their purposes and needs.
The addresses reported hereafter in this Bulletin_78 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 of Bulletin_78 is important to you, 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.
