I noticed a lot of users looking for dynamic Weld Block Symbols, I have attached a set that I have created. The descriptions are below. The attached file show an example of its use and contains the five blocks. Text style is set to "STANDARD".
There are five blocks which can be added to an existing leader:
Weld_Symbols -> This is the main dynamic block of weld symbols to cover welds described in the AWS A2.4 standard, size and spacing attributes can be edited, make sure MIRRTEXT is set to 0 if using vertical flip function for welds opposite arrow side
Weld_Options - > This dynamic block allows for the addition of either or both of the Field-Flag and All-Around symbols as well as a combination-fillet weld symbol to be added to an existing bevel or square weld, etc. when needed, field flag is flippable for proper direction
Weld_Contour - > This dynamic block allows for the flush, concave or convex contour symbols to be applied to both fillet type welds and non-fillet type welds; a designator can be added by attribute edit for countour finish letter
Weld_Tail_Left -> This dynamic block gives you a single, double or triple line option for attribute text, default is a single line of text with "TYP", left tail is for left side of symbol therefore right justified text
Weld_Tail_Right -> This dynamic block gives you a single, double or triple line option for attribute text, default is a single line of text with "TYP", right tail is for right side of symbol therefore left justified text
Remember, once you have one weld symbol in place, it is much easier to copy and use dynamic grips to manipulate it rather than inserting several times as with all dynamic blocks.
