Copy and paste it, adding a note of your own, into your blog, a Web page, forums, a blog comment, TIG welding with helium results in faster travel speed and better weld penetration. The flux is fused by the heat of the process, creating a molten slag cover that effectively shields the weld pool from the surrounding atmosphere. The types of shielding gases used impact the weld - how deep the penetration of the weld, what characteristics the welding arc has, even the mechanical properties of the joint. (You can preview and edit on the next page). The most typical setup for TIG welding aluminum involves using an AC TIG welding power source with 100 percent argon shielding gas. In some cases, nitrogen (N2) and/or hydrogen (H2) can be added to achieve special properties.
