How To Get Good Color Tig Welding
A good-looking weld is clean and is the same color as the base metal both inside and out-.
How to get good color tig welding. I know great welders who use higher heat levels but move MUCH faster than average and their welds are silver to gold in color and look like a stack of dimes. There are also other ways to accomplish the same thing watch your heat input use a large nozzle use chill bars to suck the heat out quickly or stop often to let cool. Fast travel reduces heat input.
This process of oxidization and varying levels of heat applied will lead to a variety of colors in the weld. Once again for simplicity all you need is to have pure tungsten for aluminum and either thoriated or ceriated tungsten for steel and stainless. In most cases the tungsten type used will be 2 Cerium with an orange color and an AWS classification of EWCe-2.
If TIG welding is only required for occasional jobs or a long-weld job ie. Pure will have a green band in one of the ends. TIG welding copper and copper nickel alloys are typically done with pure Argon and sometimes Argon Helium 75 Ar 25 He gas mixture.
Four Tips for a Shiny Chrome TIG Weld 1 Use a gas lens instead of a collet body to deliver a smooth column of shielding gas which is a must. You can get the lower heat input when you reduce the amperage and voltage. The first titanium weld color is straw followed by brown then brownish blue purple blue green and blue dull salmon pink gray and white oxide.
For rarer things like aluminum or exotics it will take 200 hours to get decent. The width of the bead should be consistent and have an attractive face surface profile. Most of your welds on headers are fillet welds with maybe a few laps and butts.
The five main factors that influence a colorful TIG weld are. In TIG welding it is also important that the weld is clean good-looking and the same color as the base metal inside and out. If TIG welding is the main task then a machine with a gas valve will be necessary.
