How to Weld Titanium

Titanium is a metal which is silvery gray in color and has about half the density of steel (0.163 lb/in3).  Pure titanium is relatively soft has very low ultimate tensile strength.   For use in structural applications titanium is alloyed with chromium and iron, chromium and aluminum, manganese and aluminum and manganese alone.  These alloying elements […]

Effects of Shielding Gases in GMAW

Using the right shielding gas is essential not only to prevent porosity but to get proper penetration, the mechanical properties you desire including weld strength, and overall weld quality.  In order to select the right shielding gas you need to consider the following: –          Alloy of filler metal –          Material thickness –          Mode of GMAW […]

How To Know If You Are Wasting Shielding Gas

Most manufacturing facilities use  1.5 to 3 times as much shielding gas as they should.  The reasons for this can be found in a previous post: Control Your Shielding Gas Usage. Before doing all the checks to see if you have leaks or other problems there is a simple way to get an idea of whether or not […]
