lamination scan before cathodic welding

lamination scan before cathodic welding

(OP)
Does lamination scan require prior to cathodic(cad) welding on pipe? Please let me know why?

RE: lamination scan before cathodic welding

I presume you mean Cadweld, typically used to bond copper wires associated with cathodic protection to a pipeline. No. Cadwelds do not penetrate more than 0.005-0.010 inches into the pipe. Neither Cadweld nor lamination would therefore be expected to affect the other.

you must get smarter than the software you're using.

RE: lamination scan before cathodic welding

No, BigInch totally correct, however there are some genral rules on limiting charge size, and keep these things away from welds. Why not take a wall thickness where you put it on to make sure there is no metal loss, or even do a scan to make sure it doesn't interact with anything else? A lamination may affect the fusion of the weld if large enough more than anything else...
