Welding Tips and Tricks

So I have a guy that has a wood burning stove and the latch that the door locks to is broken. I have some pictures but i am going to check it out today. I am just seeing if anyone has a a specific rod to use. Would silicon bronze work? I am going to be tig welding it because it is in his house. Not really wanting to throw sparks all over his carpet.

Just figuring out what rod to use.


Thanks

Depends on the part your welding. If it’s steel or even forged steel then just use 70s2. If it’s cast then sil bronze would be an option.

Its the latch where the door locks on to. I dont think silicon bronze will hold up to that.

SiB, used right, approaches welded steel strength. It's also probably your only option on a wood stove that has ever been used. Usually the steel/iron gets so much cr@p in it after it's been used to burn wood that you'll have a devil of a time welding it with any process, let alone tig. SiB filler and an O/A torch would be my first choice.

Many years ago my mother bought an antique cast iron parlor stove. The very ornate back panel was cracked in a pattern surrounding a series of arches. The w shaped crack ran all the way across the stove. I found cast iron filler. It is short 10"? pieces of 1/4" diameter cast iron. I welded with an acetylene torch. I'd weld an inch, then tap extensively with a pointy chipping hammer to relieve stress until no longer red hot. Then I'd weld a bit more.

It's 45 years later. The stove held, and my parents used it in their living room perhaps 20 years, until they changed to a more efficient stove.
