Where in the AWS D1.1 code is the prequalified welding procedures?

Clause 3


Can you weld rigid conduit?

Welding is not allowed by the NEC (United States' code).


Does lacquer coating on tinplate affect welding?

Yes. However, there are paints designed to be compatible with welding as they are designed to protect the surface of the plate from corrosion while in storage. In every code or specification, it is specifically stated that welding should be done on clean metal. Welding over paint is discouraged.


For rebar that is embedded in a poured slab or in a sprayed concrete wall when is welding required and when will using twisted wire suffice Can you include a link to the standard Thnx.?

Tie wire should be used always, not welding. Rebar integrety is comprimised when welded. A specific grade of rebar, A706, exists for welding but otherwise, its is not advised that rebar be welded. See below:Q: When is it appropriate to use welded splices in the field? A: The ACI 318 Building Code requires the architect/engineer to indicate the type and location of welded splices of reinforcing bars on the project drawings or in the project specifications. The ACI 318 Building Code further requires that all welded splices should conform to the Structural Welding Code for Reinforcing Steel published by the American Welding Society, which requires the project contractor to prepare written welding procedure specifications (WPS) for all welded splices. These will depend heavily on the assessment of carbon-equivalent (CE) and other rebar properties as determined by the mill test reports that accompany each shipment. For more information about welding reinforcing steel, see the American Welding Society's (AWS)Structural Welding Code for Reinforcing Steel.Q: Can tack welding be used to hold reinforcing bars during assembly? A: Field tack welding should never be used as a substitute for tying in assembling and securing reinforcing bars. Rare exceptions are specified in the International Building Code.Source link: http://www.crsi.org/contractors/faqs.html


Difference between ERW and SAW welding?

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
