    Common supplementary symbols used with groove welds are the melt-thrult-t r and backingi barrsymbols. Both symbols indicate that complete joint penetration is to be made with a single-sided groove weld. In the case of melt-thru, the root is to be reinforced with weld metal on theback side of the joint. The height of the reinforcement, if critical, is indicated to the left of themelt-thru symbol, which is placed across
