Technical Question

From what I gather from what you posted, is that you can weld, but you must adhere to the manufacturer's specifications.

 

“A frame section supported at each end loaded in the middle is in compression at the top and in tension at the bottom,” he said. “There is a neutral axis where there is no stress in the frame. Holes and welding at the neutral axis will not significantly affect frame strength. Holes and welding near the flanges can cause frame failure. Chassis manufacturers restrict the size and location of holes, and most also restrict welding on the frames.”

The frame is hardened steel,your not supposed to weld on it as the molecules will spread and weaken the frame,but the really important thing is welding on your frame causes a chemical reaction and can ruin your engine and also cook your sensors and especially your computer if you have one in your system. its really high tech but you need to ask a cat dealer,or diesel certified mechanic and a certified welder. all you need to do is ask the question on goggle,they will answer it one way or another.

 

brings back memories of mechanics of materials.


holes also cause stress concentrations, where the frame can start cracking leading to fracture.

 

What are You trying to weld to the frame??????????????
