In contrast, a welding symbol is the complete information package the designer wants to relay to the welder. A dashed line 4. The reference line: This is one of the primary elements of the welding symbol. The weld symbol is typically placed on a reference line within the welding symbol. Welding symbols are a necessary element of engineering, providing a common language for all involved in fabrication, from designers to the shop floor. On the other hand, permanent backing uses metal, similar to parent metal and filler. A 'weld symbol' is similar but different in that it is one specific symbol for one specific kind of weld. When all the welding features referenced by the combined weld have the same visibility for the sequence ID, the combined weld inherits this visibility. Plug & Slot Welds: Plug welds and slot welds are used join overlapping members, one of which has holes (round for plug welds, elongated for slot welds) in it.
