[uninformed]

hey all,

i have to cut in half an 18mm deep impact socket ("genius" brand)
and weld in a lenght of black pipe.

mig 250amp single phase.

what procedures should i take

serg

ps will cutting it with a cut off saw effect it

you should be all right, welding it will be more bad for it than cutting, but if its gets the job done... it should all weld all right.

Cutting will not effect it. If you dont know how to weld get someone that does to do it. It is not some thing that we can just explain on how to do it.
If you are going to attempt it do it out of a windy area and clean all paint grease and such of area which you are going to weld.

Ps you could do a search on welding and will find some tips.

There's a good chance the socket is a high carbon steel that may crack on cooling. But MIG is the best method to weld that type of material.

Just do it, if it cracks on cooling then try another brand of socket.
Brazing could also be an option, but much more hassle than MIG.

How long do you need to make it?
You can buy tube sockets that may get the job done.

ok,

yes i can weld. was more of a question of pre heating and post heating.

when finished it will be 1000mm long.

after welding the soket wrap it in sum flame/heat proof retarded.... i.e. use old welding gloves or leather etc, wrap it tightly and and let it cool as slow as possible

eliteforce, could you also preheat it in an oven, and then cool it down in the same manner, ie, after welding put it straight back into the oven, and then gradually drop the temperature of the oven over a period of time?

Kingy suggested the same thing for welding cast iron a while ago.

What are you useing it for as you can buy long extension bars , I've seen them at the markets up to a metre long , Cheers Paul.

I've welded sockets without pre or postheat before.
I didn't have any hydrogen cracking problems, but with different brand sockets, who knows.

doing up the tie down rods in housing construction, lets the excess threaded rod pass up through the socket, then lift off the nut and use pipe to bend over excess into roof space.
