Are there special joint preparations needed when pulse arc welding?
Pulse arc joint preparation is very similar to that of general “tungsten inert gas” – TIG welding. Some different types of weld preparation include the simple “I” seam (but joint), X, Y and V joints (named for the way they look). The “I” seam may require no filler material, while the X, Y and V require filler material and may require successive layers of material to be added to the joint. For joints were the Orion can penetrate approximately ½ to ¾ of the way through through the material an “I” seem may be appropriate. The weld location should be cleared of solder as this will reduce weld quality.
