    Need Help Deciphering Welding Instructions

    Hi guys.

    I'm a newly appointed Welding Engineer in a small company and I am the only engineer currently so I need you guys' help. In a drawing from our most recent project, the connection instructions include, and I quote directly, "Weld =8 FW/440". I was working at an inspection company before so I don't really understand what it means. Any help will be much appreciated.

    Thanks for the response Timmy. Ye I figured it was 8mm Fillet Weld. But the /440 I have no idea what that means. Here's other parts that also says the same thing.

    I've worked with welding symbols at many jobs and never saw anything like that before. All I can think of is ask for their welding spec as it may help you decipher it.

    8mm weld as TT said, it looks as if the 440 and 100 have to do with the length of the weld....somewhere....Mike

    Weld =8 FW/440........would think that the 440 part is short for 440n/mm2 and refers to yield strength and rod selection. This Lincoln page for 6010 shows the 440n/mm2 notation near the bottom.

    @ OldSparks - concur. Seen similar notation in DNV classification for welding offshore structures.
