Welding Bolts to Steel Block (Gate Hinge)
Welding Bolts to Steel Block (Gate Hinge)
(OP)
I'm new here. I am building a set of driveway gates here:

The hinge is a prefabricated block and pin that I want to weld a 3/4-10 bolt too. The design is here:

My welder doesn't like the hinge design; thinks its too weak.
I see that maybe using SAE-5 is not smart, so maybe I should purchase Nelson SS studs. Anyone see a problem with this design. I think maybe the real reason the welder doesn't like it is its too hard to fabricate. Anyone have another idea?

First, welding was difficult in the field...we did not have access to TIG, which possibly could have made the welding at least, prettier and failure may have been postponed a bit longer. The failure was in the TS. The original specs were for four hinges and two gates. Someone did not like the looks of two gates and field change to one big gate but never addressed the hinges...That is a guess on my part as I did the "as builts" at a later date and noted the change. My crew did the fabrication and welding which passed the hospitals inspectors review. I only found out about the failure a couple years later because my daughter was a supervisor for Kaiser billing, then using the building.

The question has to do with welding the bolt to the block. My experience has always been that welds are stronger than the parts themselves. If that is true, and we achieve full penetration of the weld as shown on the drawing, I don't believe the weld will break before the bolt bends. Am I wrong?
Evelrod: What is "TS"? MagMango: The purpose of the bolt is for adjusting the gate. Speaking with several gate builders, coupled with my own experience, over time, the gates sag, and the posts move requiring a welder to cut the hinges loose, shim and reweld. This is to eliminate that problem. The gate fabricators I have spoke with like the idea of an adjustable hinge.

You asked if anyone had done this...I never indicated your gate would have a problem. I feel my problem of years ago may have little to do with yours.
