These are the advantages of weld-fabricated parts<\/p>\n

    \n
  1. Better mechanical properties<\/strong>\n
      \n
    • They are manufactured <\/strong>from rolled plates or profiles that typically have greater strength and toughness than many cast materials<\/strong>.<\/li>\n
    • Lower risk of internal defects<\/strong> such as porosity or shrinkage cavities.<\/li>\n<\/ul>\n<\/li>\n
    • Lower weight<\/strong>\n
        \n
      • The structure can be designed with optimised thicknesses<\/strong> and reinforcements, avoiding large solid masses.<\/li>\n<\/ul>\n<\/li>\n
      • Simpler manufacture for large parts<\/strong>\n
          \n
        • No giant moulds <\/strong>or large casting furnaces are required.<\/li>\n
        • They can be manufactured in sections<\/strong> and then welded together.<\/li>\n<\/ul>\n<\/li>\n
        • Greater design flexibility<\/strong>\n
            \n
          • It is easier to modify dimensions or add reinforcements during design<\/strong> or even during manufacturing.<\/li>\n<\/ul>\n<\/li>\n
          • Ease of transport and assembly<\/strong>\n
              \n
            • Large parts can be manufactured in modules <\/strong>and assembled afterwards.<\/li>\n<\/ul>\n<\/li>\n
            • Easier repair<\/strong>\n
                \n
              • They can be repaired by welding or replacement of sections<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                However, cast components also have significant advantages:<\/p>\n

                Advantages of large cast parts<\/strong><\/p>\n

                  \n
                1. Monolithic part (no welds)<\/strong>\n
                    \n
                  • There are no weld beads<\/strong>, which can be critical areas if poorly executed.<\/li>\n<\/ul>\n<\/li>\n
                  • Complex shapes in a single part<\/strong>\n
                      \n
                    • They allow very complex geometries<\/strong> with internal cavities or ribs.<\/li>\n<\/ul>\n<\/li>\n
                    • Good vibration absorption<\/strong>\n
                        \n
                      • Some cast irons (such as grey cast iron) dampen vibrations very well,<\/strong> which is why they are used in machine tool beds.<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

                        We could draw the following conclusions from the above:<\/p>\n

                          \n
                        • For large and heavy structures <\/strong>(bridges, large frames, tanks, heavy machinery) it is generally better to opt for weld-fabricated parts.<\/strong><\/li>\n
                        • For complex, solid components<\/strong> or those that need to dampen vibrations, casting may be preferable.<\/li>\n<\/ul>\n
