How To Get Color When Tig Welding
The formula to calculate the heat input is 60xAmpsxvolts 1000 x travel speed in inmin KJin.
How to get color when tig welding. A good-looking weld is clean and is the same color as the base metal both inside and out-. The formula to calculate the travel speed is the length of the weldtime to weld. All too often we see first time TIG Welders struggle with the basics and this can lead to frustration and a long learning process.
That is why gas welding steel with an oxyfuel torch looks so gray all over. Color in a weld is a sign of oxide. The color chart and acceptance criteria for titanium welding are established.
We cover basics for beginners who want to TIG wel. This process of oxidization and varying levels of heat applied will lead to a variety of colors in the weld. Thoriated will be red and ceriated will be orange.
In most cases the tungsten type used will be 2 Cerium with an orange color and an AWS classification of EWCe-2. Tungsten for tig welding is color coded. After welding finished the welding quality can be evaluated by visually checking the discoloration of welding surface.
Once again for simplicity all you need is to have pure tungsten for aluminum and either thoriated or ceriated tungsten for steel and stainless. The color forms due to the contact of the weld pool of metal with oxygen. A TIG welder needs a filler rod to provide the welding bead when joining two pieces of metal together TIG welding produces no sparks or spatter because only the necessary amount of filler metal is added to the welding pool.
Two the filler rod does not join or melt smoothly into the weld puddle. Fast travel reduces heat input. Learn how to TIG Weld.
