help me understand this BS symbol.

This is a British Standard symbol. I know its a plug weld. But where?

[sturugged]

Looks like a spot weld or a projection weld, might be mistaken though

[killdozerd11]

That would be in the only hole there seems to be

The rest is a mechanical drawing of the part and has no other holes and only one welding symbol and i think it is on your side of the arrow
but there are no references as to what the notations in the tail mean

I think the 8x refers to the spot welds , 8 in total, the 4x refers to 4 welds per side of the unit , as it it kinda a laminated sandwich, 4 welds topside 4 welds on the bottom. this details the 8 total welds req'd

That's how I read it...but what is with the dashed line on top? Is that a bad way of saying stitch weld far side?

I got that part. Im thrown off by the arrow pointed at the center. I think its a plug weld on the near side of the arrow. like this?



I would think it would call for something like this.

If the symbol is on the solid line it means near side. If it is on the dashed line it means far side. The circular symbol can meam plug weld or projection weld.

AGAIN...IT IS NOT A PLUG WELD!!! There is no hole to "plug." It is a SPOT weld at the crosshair/tip of the arrow...

Thats what I thought. so my last post/pictures were correct?

whats with the SCREAMING. I think your wrong. A spot weld at the tip of the arrow would not even join the pieces together.

It is plug weld cross hatch lines designate hole or it wouldnt be centered FS is far side NS is near side and as for the broken lines on top of the arrow its probably to designate the holes inside the piece most likely a poor detailer did this becuase there is no need for the hidden lines if it was a stitch weld it would have pitch and length desingnated such as 1inch on 3 inch center.
