I doubt your client will want anything super complicated, but there are a few basic welds that every engineer might want to know. The figure to the right will give you an idea as to how welds are decided. Typically you look for the basic geometry of how your two metals will be locked in place. If you have questions, ask your client for some guidance, but provide a couple of options you have researched and think are the right ones.

This way they know you are dedicating time and effort, and not just looking for a free answer. Perform welding calculations Once you confirm with your client that you have chosen the correct welds, it's probably about time to do calculations.

Now your client might have provided a standard as ours did for welding.

If they didn't, there are a few helpful references you could use. Blodgett -Design of Weldments, by Omer W. Blodgett -AWS D1.

We used AISC for our project, and once you get the hang of it, it is quite easy to use.

You will find that this book references AWS D1. Find your minimum effective weld size referring to throat of weld , you will determine this from tables J2. Nearly every time you are welding right angles to each other, you want to use fillet welds. If you are using Hollow Square Section HSS tube , you will probably be looking at flare bevel welds depending on the joint type.

Note: while these minimal weld sizes are standard, if you find that your calculations give you a crazy design ratio, consider making it smaller and or shorter. There is a caveat in there, stating that it is OK to use smaller weld size than the 'minimum' as long as your calculations prove it to be safe.

Next you will use table J2. Our client did not want us sharing any of the work we did, so I would suggest asking your client for sample welding calculations so you can better understand calculating design ratio and allowable strength vs design strength. Blodgett Leadership Award Winner Dr.

Blodgett and Wife Dorothy Omar Blodget is a legend in welded steel structures. He turned 90 on November 27, Blodgett earned bachelor degrees in metallurgical engineering and mechanical engineering from the University of Minnesota.

He accepted a position with Lincoln Electric Co. He is recognized nationally and internationally as an expert in the design of welded connections and has been influential in the development of national standards to the code of the American Welding Society.

He is the author of several significant papers on sizing welds, control of distortion, brittle fracture, and fatigue.

Which, even though originally published over 40 years ago, are considered to form the foundation for the entire field of design for welding. Higgins Lectureship Award.

He received an honorary Doctor of Science degree from LeTourneau University and in Engineering News Record identified him as one of the top engineers in the past years. In the words of Dr Fisher, another great steel designer: "Most structural engineers think of Omer as an icon in the field of structural engineering.

The amazing fact is that most do not realize that Omer was not educated as a structural engineer. He studied mechanical engineering and metallurgy.A ' long welded bridge spanning the tracks of the Erie Railroad on the New York Thruway had to be shaped to meet site requirements.

The spandrel beam is shop welded to th e column for lowest cost and shipped to th e site.

We shall also present guides to aid in recognizing those situations wherein the use of high-strength steels has proven to be advantageous. So it's a good thing to learn early in life.

Table 2A for shapes and Table 2B for ,l: lates show the comparative prices of the five ASTM structural steels and proprietary high strength, low alloy steels.
