- 75 150. The welding symbol will not convey which leg size is the larger size and which is the smaller size. 2 Dimensions of resistance seam welds may be shown on either side of the reference line.

Any welded joint indicated by a symbol will always have an arrow side and an other side. Weld symbols indicate the type of preparation to use or the weld type. Upset weld flash weld and friction weld are included.

The dotted line indicates the weld side. However there may still be occasions where other information is required. This symbol signifies that the weld needs to be machined or ground back flush to the level of the rest of the plate.

The convex finish of a weld curves outwards like a balloon away from the weld just as its symbol displays. A reference line 3. Name Weld between points Weld.

Weld With Flat Face. The welding symbol describes the whole thing while the weld symbol can be part of the welding symbol. Name Finish Weld Symbol on Symbol base platform weld.

Resistance seam weld symbols must be centered on the reference line. The tail of the weld symbol is the place for supplementary information on the weld. Consumable insert entirely around Symbol on base platform weld.

The symbol on the near and far side represent the type of weld surface. Name Fillet Resistance Spot Resistance Steam. Doubleflanged Singleflanged Square groove.

A welding symbol is an effective way to communicate the weld necessity among workers. In front of the symbol place the number of welds followed by the weld length - after the symbol place the spacing between welds In brackets 3 x 75 150 Again If the number of welds are either not known or not necessary simply leave blank eg.
