unclesyd,
thanks for the reply. i will check whether there is anything welded behind, but I am pretty sure not.
interesting to know about the minimal thermal cycling. i think that the original cracks are from stresses in the original welding of top and bottom case of the muffle. would this be...
edstainless, thankyou. you are right about the distortion. we need to have a look at the furnace and see whether patches or grinding out the old weld is best. obviously the existing form was stressed or it would not have cracked in the first place. i worry that patches and more welds (joining...
racookpe1978 - thankyou - completely understood and completely obvious now you have said it. we will look into it. this makes much sense. greater than operating problems i think that the new welds are contributing greatly to the cracking. thankyou.
Thankyou for your consideration metengr and EdStainless. So you both suggest cutting and patching, which makes sense. Probably to match the curved form also, which looks like it is formed to alleviate any stresses from expansion and contraction.... Again this would form strong areas and local...
I am about to help weld a furnace which has developed cracks in the stainless steel jacket, where it was formed to alleviate stresses. The cracks have already been welded once, and are now re-appearing, either on the weld or beside it. The owner said that the company who supplied it here did not...
