I just purchased another 100' of 3/8" anchor chain for my boat which i want to splice in with the chain i currently have. I know they make chain coupler which are basically two halfs which you put together and hammer these tabs (kind of like a rivet) to hold the two halves together. But what about cutting open one link of the chain and tig welding it back shut? Is there any reason why this can't be done? Seems stronger and cleaner then using one of these couplers. How would you guys splice chain? Thanks in advance.
