A question popsted in the Inspetion News forum for home inspectors:
"I, found a 1/4 " hair line crack in the front weld in a heat exchanger. The unit was over 30 years old in average condition, I did call for a licensed heating contractor to evaluate the condition and advise for replacement or repairs. My question is this, Does any crack in a heat exchanger need to be replaced or can it be repaired if the person doing the repairs guarantees their work?"
I've never heard of weld repairs being OK, but wonder if someone (Tim?) has some definitive knowledge.
