Can anyone recommend welding rods?

Post  rob spence on Mon Mar 05, 2018 10:20 am

Hi, I'm going to use a stick welder to weld a mild steel exhaust pipe for a trials FB, new steel pipe.
Can anyone recommend the best type of rod for mild steel?

Unless you are a very experienced welder then your going to struggle welding exhaust pipe with a stick welder.
TIG would be first choice, then gas, then mig.

If you have no other option start with a 1.6mm rod power turned down and try not to get much heat into it, do short sections 1cm at a time and be prepared for a lot of grinding/filing afterwards.

Unfortunately I have to use the stick welder.
What I'm after is a recommendation for rod type ( number).
Thanks rob.

Welding

I know you say you have to use a stick welder but sooner you then me. It's been many years since I used one but I guess a cheap mild steel rod. Why not tack it with stick and then take it and get mig or Tig welded.
I bought my bends in stainless from eBay and made the shape. Tacked it and got it done with a Tig. Its so neat you hardly see the weld .

Welding rods

Post  colk2004 on Tue Mar 06, 2018 9:42 am

Years ago I did some nice stick welding on a kit car on 1.6mm steel with a Clarkes bottom of the range arc welder. Using Machine Marts rods - the secret was I used most of the rods practising and getting everything spotlessly clean. After this job was done I went straight out and bought a cheap SIP mig which did the job way better and easier. I recently sold my SIP mig for 50 including delivery so good cheap migs are out there. I would never g back now unless I needed to weld stuff over 5-6mm.

, oxy acetylene is best for this type of work. cleaner weld and neater. welding rods will burn melt through.
