Hints for Welding Cast Iron Tubs

While cast iron baths are known for their long lasting durability and strength, they do break down over time (though that time period is quite a lot longer than manufacturing materials used to make bathtubs). Small cracks can and do happen. Over time the joints on the tub may see some wear and tear. Many people assume that welding cast iron tubs is the best way to mend cracks and joints and fixture breakages. The problem is that cast iron has a higher carbon content than most other metals, which will make it quite a lot harder to weld. If you are determined to complete your cast iron repair by welding cast iron tubs in your home, here are some hints:

1. When welding cast iron tubs you need to make sure that you keep everything out of the one hundred and fifty to five hundred degrees Fahrenheit range. It is a good idea to do some preheating but you can also do cooling. It is not a good idea to change your methods mid-welding project.

2. If it is possible to pre heat the part for your welding cast iron tubs project than you should do it. Do your best to heat the part's whole casting uniformly until it sits between five hundred and twelve hundred degrees Fahrenheit. Overheating can cause bigger cracks to form. Low currents can help you minimize the stress in your cast iron repair project and cut back on the admixture as well.

3. The cast iron should be kept cool but it should not be cold. At the same time you should always be able to touch the casting with your unguarded hand. If the casting is too hot to touch without needing gloves then the casting is too hot. The best way to avoid overheating is to make welds around one inch in length.

4. Do not panic if, in the process of your welding cast iron tubs during cast iron bathtub installation, small cracks may appear. Even when you do a perfect welding job in your cast iron repair project small cracks will probably show up. You can use a sealing compound to keep them water tight.

5. If major cracks appear you can fix them by doing some studding. Screw steel studs into pre-drilled holes and then tap them into the surface that you want to weld. Keep the studs between five and six millimeters above the surface of the cast iron tub. Weld these studs into place and viola! A fixed crack!

Repairing something made out of heavy metal can be a difficult undertaking. "Fixing" metal construction is not easy at all. Welding cast iron tubs is very controversial. There are some who insist that welding cast iron tubs is not a good idea at all while there are others who will insist that welding is the best form of cast iron restoration. Whether or not you use welding to fix your cast iron bathtub is up to you and the extent of the damage that needs to be repaired.
