Yes these blocks were welded to let the dolly drivers know what side to pick the shafts up on. There may have been other reasons that are unknown to me.
It looked like to me as well that part of the fracture happened right around the penetration of the weld. I thought the heat from the weld...
Here are the pictures of the part

Hey fellas thanks for the replies. Sorry I have been out of the office (I'm actually still in school and only work on Tue/Thur part time). I have attached a sketch of the part that I have been reffering to. I will try to get a picture of the actual failed part this afternoon.
Attached is the...
Well this shaft was not in use (not rotating). It was being lifted and snapped off at the end. Sorry I should have stated that in the orignal post.
I'm not sure on the speed the lifted the part at. I was just told they lifted it and it snapped. I would assume that it was somewhat slow, but...
Hello everyone I have a problem that I need some help with.
At my place of work as a co-op we had a part fail. This part is a shaft thats dia. 6" and steps down to a dia. 4.125". There is a 3/8" fillet to help reduce stress. The material is AISI C-1015HF, I believe. This part snapped in...
Yeah we could do a load test but everyone knows it will pass (I think my saftey person just wants it on paper for proof incase something happens, but I am not really sure). Being that there is really more than one bar to support the weight, im using the worse possible scenario with all the...
Aconnell: I have just taken a mechanics of materials class but we did not cover welds, I'm thinking I will learn more about them next semester in machine design.
I am an intern so this project was given to me. The saftey person here just wants me to prove it can withstand a 200lb force. I...
Well that is the thing, I don't know much about the weld or who welded it so my information is somewhat limited.
BTW I said butt weld yesterday, but its a fillet weld. Sorry for the confusion.
I found this site taht has some information, but it looks like it will tell me a shear stress. Does...
OK so here is the situation. I have a part that has a 36" long piece of box tubing welded on both sides to a frame (box tubing dimensions: 1" x 1"). I need to prove with equations that this device can support a 200lb load. Im assuming that welds will fail before the beam it self fails so I am...
