How to properly weld aluminum
What makes aluminum welding so difficult Aluminum has one property that makes welding this metal so difficult: as soon as aluminum is exposed to the ambient air, it forms a wafer-thin layer of aluminum oxide. And it is this layer that gives the metal its unmistakable silver-gray appearance. But i...

Welding Tip
Zero colour oxide free welds for manual welders Titanium, stainless steel and other corrosion resistant materials need to be shielded with an inert gas while welding takes place, in order to protect the molten weld pool from combining with oxygen and nitrogen from the surrounding air. Without thi...

Seven Tips for Inert Gas Welding
Effective welding purging is only achieved by making sure that oxygen is displaced from the purge zone prior to and during welding. Any residual oxygen can cause significant loss of corrosion resistance and a reduction in joint strength. It is therefore essential to seal the pipe either side of...

Why use Inert Gas Purge when Welding Nickel Alloys?
Why use inert gas purge when welding nickel alloys? By purging the internal space with inert gas, it is easy to prevent oxidation, thereby avoiding discoloration and discontinuities in the weld in the pipeline. This simple process can save time and costs, both of which are considerable. Consider ...
