Cut and weld a splice from a donor frame or fabricate a piece to weld in.
Automobile frames are repaired and welded all the time, it's not illegal. Sometimes this job is best left to the professionals unless you are an experienced welder capable of doing quality work. If you don't know what you are doing you can quickly ruin a vehicles frame and create a dangerous or even deadly situation. So while it may not be illegal to weld your cars frame you should ask yourself if it's wise to do it yourself, if not let a pro do it.
As long as you disconnect the battery (or batteries) first, you should be fine. Basically, disconnecting at least the negative cable breaks the circuit thus protecting the electronics.
yes if allowe to dry 24 hrs but should NOT be used on lines or tubeing or any pressure point ... if youre fixing the resivour it should be fine if the parts repairing are reaaallllyyy CLEAN No J-B Weld is not fully resistant to brake fluid. I used it on a brake resivour for a motorcycle. It held up for a few years, but over time J-B Weld was broken down by the brake fluid.
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.
