welding stainless exhaust box....
I noticed today a wee line of bubbles coming out of the weld on the entry side of the stainless exhaust box on my olde ship. The motor is an MD17C.
I cannot face replacing the whole unit. Not right now anyway. I will buy a new exhaust box, and fibre-glass is attractive, but we will try welding first, if practicable.
The weld has gotten a bit tired. I had hoped to weld it in situ as the exhaust hoses will be very difficult indeed to remove... they were very difficult to get ON, some 12 years ago..... so is suspect I will tear something up trying.
It may not work, but I am trying only to re-establish the weld, and nothing else.
A guy I know has a welder and we could transport it the 90 miles to the boat.
Is stainless relatively easy to weld? I know we must use chrome-rich electrodes, but what else must we watch for?
