Use WPS (Welding Procedure) AWS D1.1 from Parent Company?.

Not without carrying out an acronymectomy first. TLAs are NBG.

I think you need to show that the new company's welding equipment and personnel can produce satisfactory welds by following the preeexisting procedures.

@PWSlack: sorry, I don't know about your comment

@Tornado: So will we write new WPS and use existing PQR for supporting (no need weld and bend test, tensile test...again)?

I think that in order to have any meaning, your subsidiary (I assume since you cite AWS you are located in the U.S.) should be reqistered with the AWS; you will have a book of pre-qualified welds; you will have a certified welding superintendent and you will have a welding engineer - either on staff or as a consultant.

If the parent company is registered, you should ask their welding engineer whether their membership covers the subsidiary.

AWS D 1.1

4.1.1.1 Qualification Responsibility.

Each manufacturer or Contractor shall conduct the tests required by this code to qualify the WPS. Properly documented WPSs qualified under the provisions of this code by a company that later has a name change due to voluntary action or consolidation with a parent company may utilize the new name on its WPS documents while maintaining the supporting PQR qualification records with the old company name.

Ok, I will write new WPS with the new name company (name of subsidiary company) while use old PQR with name of parent company.

Thank all

PS: any more discussion or advice is highly appreciate
