The formula to calculate the travel speed is the length of the weldtime to weld. In most cases the tungsten type used will be 2 Cerium with an orange color and an AWS classification of EWCe-2. After welding finished the welding quality can be evaluated by visually checking the discoloration of welding surface.
To get rid of grey or dull color you need. March 24 2015 By. The formula to calculate the heat input is 60xAmpsxvolts 1000 x travel speed in inmin KJin.
The color chart and acceptance criteria for titanium welding are established. 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.
