No . . . that would be extremely dangerous.

Yes. A really good TIG welder can do this. Ask around at radiator shops. JB Weld never works on this kind of stuff.

Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.


Can you use jb weld on freeze plug leak?

Sounds like a real bad idea. A leaking freeze plug is usually a sign of a very neglected cooling system. You need to replace the leaking plug with a new one. Unfortunately there is probably corrosion throughout the whole cooling system. You will probably have other leaks soon.


What is weld mapping?

Weld mapping are visible marks that are seen on metal welded parts. Either they are welded together or repaired and sometimes you can tell who welded it, and when the weld was placed. Weld mapping is the process of assigning information to a weld joint to enable easy identification of its design (WPS), production (welders, their qualifications, date welded), quality (visual inspection, NDT) and traceability (heat numbers of materials joined & welding consumables). Weld mapping should also incorporate a pictorial identification to represent the weld number on the fabrication drawing, in case the designer does not nominate a weld number. You can use online weld mapping software such as Smart Welding Manager to create weld maps that provide 100% traceability as well as a pictorial representation.

Can a cracked plastic tank at the top of a radiator be fixed or must you replace the radiator?

Replace the radiator. Try JB Weld or JB Kwik Weld on the crack first -- you can pick it up for $4 and it is definitely worth a shot. I have tried the jb weld it didn,t work . I had to buy a new raditor ANSWER I work in a shop where we routinely replace the plastic tank. If you have to repair the plastic tank then do it from the inside. You can separate the tank from the core by carefully loosening the aluminum tabs holding it in place.
