When spot welding or arc seam welding extends for the full distance between abrupt changes in the direction of welding, no length. Welded linear seams are without start/end weld craters, uniform across the entire seam length, free of discolouration with stainless steel. Longitudinal weld or Longitudinal seam both are identical terms used in fabrication industries to point out the weld made along. Another major difference is the two parallel lines that go through the elongated circle. H = Heat developed in joules.
