\n\t\t\t\t\t\t\t\t\tWhen stud welding, it is important that you carefully adhere to the following guidelines, including the time and amps\u00a0by stud diameter.\r\n

Stud Welding Guidelines:<\/h2>\r\n
    \r\n\t
  • Set appropriate time for the weld base diameter.<\/li>\r\n\t
  • Set appropriate amperage for the weld base diameter.<\/li>\r\n\t
  • Ensure that the negative polarity is to the stud gun.<\/li>\r\n\t
  • Align accessories so they are centered and adjust legs so that 3\/16″ to 1\/4″ of the stud protrudes beyond the ferrule.<\/li>\r\n\t
  • Ensure a good, clean ground connection.<\/li>\r\n\t
  • Keep work surface relatively clean so that impurities don not affect weld.<\/li>\r\n\t
  • Keep studs and ferrules clean and dry.<\/li>\r\n\t
  • Test welds at the beginning of each shift or change in stud (AWS Bend Test).<\/li>\r\n\t
  • Check burn off (1\/8″ to 3\/16″ depending on stud diameter).<\/li>\r\n\t
  • Check weld fillet (360 degrees).<\/li>\r\n\t
  • Visually inspect all welds.<\/li>\r\n<\/ul>\r\n
