TIG Welding

At a glance..

In the TIG (tungsten inert gas) welding process, an essentially non-consumable tungsten electrode is used to provide an electric arc for welding. This instructional guide will help you with TIG welding.

The details..

The book is a comprehensive guide on Tungsten Inert Gas (TIG) welding, which uses non-consumable tungsten electrodes and inert gas shielding to prevent oxidization during the process. The author explains that unlike Metal Inert Gas (MIG) welding where metal is continuously melted and added into the weld, no metal is added unless using separate filler rods in TIG. This technique can be performed with various metals; however, steel and aluminum are commonly welded at PRL.

The author emphasizes that although aluminum takes more skill than steel when it comes to TIG welding, basic techniques remain similar between both materials. With practice, one can produce tight neat welds much faster than oxy-acetylene-welding while avoiding oxidation issues.

Moreover, this book describes different controls available on two Miller Syncrowave machines owned by PRL- stationary 300 model & mobile 250 DX model - along with their interfaces' functions such as power switch turning machine off/on or current control dial setting flow amount between torch & workpiece etc.

Finally,this instructional guide includes information about frequently/infrequently used controls like range switch toggling low/high ranges,current control dial selecting current level flowing through foot controller,polarity switch direction selection during DC Welding,and high-frequency switches controlling superposition/start voltage over normal voltage among others.
