I was questioned about my welds today and would like to let you all know that a Teck screw will hold on a 3mm screw a quarter of a ton in sheer. I would think the wood would give away first but it doesn't. Then my crane on my trailer will hold a ton on a meter radius with four 1/2" bolts in tension. The load is only on two of those bolts at a time. So how much will my welds hold?
6" long weld with a depth of .25" well 6x.25"=1.5 sq inches
Steel carry's a load of 25 tons per square inch so my welds should carry 37.5 tons
