Welding process for cracks in the housing of gray cast iron gearboxes
Thread Content
Recently, a gear box in our company developed a crack about 300 mm long on its upper housing (the size of the gear box is approximately 1200×500×800 mm). One end of this crack started at the bearing seat for the second shaft, and it ended at the rounded corner of the observation hole on the top. Concerned about poor welding quality, a new enclosure was purchased. But personally, I think as long as the welding process is properly arranged, there should be no problem using welding for repairs. What are your thoughts, fellow sailors?
You’re right, but a crack this long can’t be fixed with ordinary repairs; the cost of fixing it might be much higher than the price of buying a new one
