Can you JB weld a cracked transmission?
Re: Does JB Weld hold up to tranny fluid? Yes, if you clean the oil off, it will easily repair holes and cracks, been there, done that, Brake cleaner and some compressed air are you friends.
Can you weld a broken transmission case?
but to confirm yes you can weld a cracked cast aluminum transmission case.
What will J-B Weld not stick to?
When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld.
Which J-B Weld is strongest?
J-B WELD ORIGINAL: The Original Cold Weld two-part epoxy system that was designed as an alternative to torch welding. J-B Weld Original provides strong, lasting repairs to multiple surfaces and creates a bond stronger than steel….

Which JB Weld is strongest?
Is J-B Weld a permanent fix?
J-B Weld™ is The Original Cold Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing.
Is J-B Weld stronger than welding?
J-B WELD ORIGINAL: The Original Cold Weld two-part epoxy system that was designed as an alternative to torch welding. J-B Weld Original provides strong, lasting repairs to multiple surfaces and creates a bond stronger than steel. J-B Weld™ has a tensile strength of 5020 PSI and sets to a hard bond overnight.
What kind of cracking is done on a weld?
This type of cracking is also known as “underbead cracking,” “toe cracking,” or “delayed crack- ing.” Because this cracking occurs after the steel has cooled below approximately 400°F, it can be called “cold cracking”, and because it is associated with hydrogen, it is also called “hydrogen assisted cracking.”
Which is more common transverse weld or longitudinal weld?
Transverse weld metal cracks are perpendicular to the direction of the weld. This type of crack is more common in welds that have a high degree of restraint. Longitudinal weld cracks travel in the same direction as the weld and are often confined to the center of the weld.
Is it possible to repair a crack in aluminum?
Yes, in one very important way. Remember that aluminum forms an oxide layer almost immediately upon exposure to air. The crack’s surface also has an oxide layer. If you try to repair the crack merely by welding over it, the oxide layer will keep the crack from mending, and it will still be there after welding.
What kind of cracks are found in steel?
Cold cracks in steel are sometimes called delayed cracks and are often associated with hydrogen embrittlement. We can divide cracks into an additional two types: Cracks in the base material and cracks in the weld metal. Heat-Affected-Zone (HAZ) cracking is most often associated with hardenable base material.
