Definitions

  • a means for melting the welded portion for example, one using electric discharge, electron beam, or laser is used.
  • Examples of the method using electric discharge include tungsten inert gas welding and arc gas welding.
  • Ra is almost the surface of the weld with a surface roughness of 0.3 / m, but at a welding speed of 40 RPM or more, Ra increases with increasing welding speed. It can be seen that the value of a has increased.
