Hi, does anybody have experience with implementing SSoW for welding operations? I've been asked to help a Company who will be MIG welding rebars into cages rather than tie on site and the information I've found so far is a little mis-leading with regard to exactly when it is required i.e. at all times or only in certain circumstances? I'd appreciate you sharing your experience or being pointed to some decent guidance. Thanks, Alan

Alan, As Jane says, also there is some info on the COSSH essentials website the bottom link on the main page IIRC. Where you can get further info. One thing with MIG (MAG) you don't want the shielding gas sucked away! Clean rebar is plain low carbon steel so a copper coated low carbon steel filler wire should be OK. Contaminants may be an issue. Shielding gas? As Jane says transfer process? Give us some more & we will try to give you some more.

john, If they are using high carbon steel rebar then there should be welding procedures in place to cover the pre/post heat treatment etc. to prevent the formation of martensite and the assosicated structural changes that ocurr from the rapid heating & cooling of high carbon steels when welded, thus they should have engineering input to this to ensure that the welds & associated heat affected zome do not become the weak points of the structure surely.
