Shielded metal arc welding tests for structural type work are specified by the American Welding Society Structural Welding code for Steel. AWS D1.1 is the name of the code book.

There are numerous AWS welding codes for all kinds of industries and the welding certification tests for shielded metal arc welding are usually pretty similar from one code book to the next. The American Welding Society provides code books for heavy equipment, Bridge Welding, Sheet metal, Titanium structures, Aluminum structures, Industrial Cranes, steel and aluminum hull welding for ships, aerospace welding, and a whole lot more.

The common thread that runs through all these code books is this:

Before any coded welding can begin, welding procedures need to be qualified

Welders need to be certified using the procedures that have been qualified

Welds need to be inspected by a qualified person

When it comes to Shielded Metal Arc Welding, There are AWS welding procedures for sale that are prequalified. They are not free. In fact, if you buy a pre-qualified welding procedure... for the few pages you get, you might thing you got ripped off. But odds are, you just saved yourself a whole bunch of money and headaches in the long run.

Prequalified welding procedures are produced with a lot of input from volunteers in the welding industry. Is a round robin kind of thing where several different companies produce welds to a given set of parameters and they all agree that acceptable welds can be done using the procedure.

There is safety in numbers. If company X, Y, and Z can all agree that good welds can be made that meet visual inspection criteria, non destructive, and destructive testing, as well as other mandated tests, it seems reasonable to believe that the procedure works.

Companies are free to re-invent the wheel and test their own procedures but it usually winds up costing more in the long run. It is wise to go ahead and buy the pre-qualified procedures. Especially when there is the likelihood of an audit from regulatory agencies. The AWS has more clout than you do.
