Welding: Creating the World “Every building is a prototype. No two are alike.” (Helmut Jahn). Every welder has their distinct technique; no two welders weld alike. Indeed‚ welders are the ones responsible for the structure of a building by welding to pieces of metal together they are slowly placing it together. The education needed for a welder is basic all you need is a high school diploma. Their job responsibilities are melting two pieces of metal together. Depending on their employer will depend

WELDING TERMS 2 1.) DISCONTINUITY: an interruption of the typical structure of the weld. It may be a lack of uniformity in the mechanical‚ metallurgical‚ or physical characteristics of the weld. A discontinuity is not necessarily a defect. 2.) DEFECT: according to AWS‚ “A discontinuity of discontinuities‚ which by nature or accumulated affect (for example‚ total porosity or slag inclusion length that renders a part or product unable to meet minimum applicable acceptance standards or specifications)
