What are the 3 Biggest Mistakes in Titanium Welding?

You might think the #1 biggest mistake in titanium welding is failing to clean or purge with argon.

Both these are important but the biggest mistake you can make is accidentally using the wrong rod.

1G titanium weld test - based on AWS D17.1 aerospace specs

A 1G weld test in the .020" -.063" thickness range on 6AL4V titanium is a very common test for aerospace welding.

.040" thickness is very commonly used to titanium welding tests like this.

2G Titanium Weld Test Based on AWS D17.1 aerospace specs

Cleaning the edge before welding is key to passing any titanium welding test.

A 2G test is more likely to show porosity on X ray than other positions so clean those edges thoroughly before welding.

The main cause for failure on a titanium weld test is porosity and porosity is mostly caused by some type of contamination like oil or embedded grit from a sanding disc.

the x ray negative below shows scattered porosity in a titanium weld.

Best practices for Titanium Welding

wipe titanium with acetone first to remove any residual oils or shop dust
brand new clean titanium might only require degreasing, wire brushing, and deburring before welding. Make sure to use clean stainless steel brushes that are dedicated to titanium use only.
If abrasives are needed, make sure they are fine grit and dedicated to titanium use only
Purge the back side of any area that might exceed 1100F
