Determination Of Weld Loads And Throat Requirements Using ...
Jective of this analysis is to determine the weld size, S, that results in a maximum throat stress of 13.2 ksi. The loads in the weld are easily de-termined using classical analysis for this bracket. The weld size requirements will be calculated first, using the loads from finite element analysis and then will be compared to the results ... Read Full Source

Spot Welding - Wikipedia
Spot welding is typically used when welding particular types of sheet metal, welded wire mesh or wire mesh. Thicker stock is more difficult to spot weld because the heat flows into the surrounding metal more easily. Spot welding can be easily identified on many sheet metal goods, such as metal buckets. ...

Analysis Of Welding Shrinkage - American Welding Society
The analysis provides a simplified ap­ proach for estimating welding shrinkage. Introduction Welding is the most frequently used metal joining method, and the complex problem of welding distortion is an ob-stai le that must be overcome. During the heating and cooling cycles while weld­ ing, thermal strains occur in the metal ... Read More
