Heat Shrinking Aluminum Sheet Metal

Alternatively you can try hammering off dolly to move the metal around a little to where it needs to be.

Heat shrinking aluminum sheet metal. Using intermittent welding rather than continuous welding where possible greatly decreases distortion. Usually you can get away with a few small shrinks before the metal starts to work harden too much. Considering aluminum does not change colors when it is hot purchase a temperature crayon at a home or auto body supply shop before shrinking. If the metal plate is thicker than 0 25 beveling can help ward off distortion.

This works the other doesn t. Your shrink temperature is much much. Do not over heat the steel. Although dent shrinking can be achieved with a shrinking disc or a spitzenagle stud nailer gun in order to shrink a bead you will need a heat source that produces a flame.

If you feel that you would like to help support trev s blog channel please consider making a donation money raised from donations will be used to buy tools. Pulling everything into a tight spot and making the metal soft enough that when struck with a hammer the excess material is pushed out into the surrounding area eliminating the build up of too much material in that one area. Effectively it gives us a shrink. If you need to shrink in the center or where you can t get a shrinking tool in you must heat shrink either with a torch or a shrinking disc.

Heat to blue only and shrink that much. Get used to this idea and your abilities will grow. It s basically the same basic process with this one major difference. Even though weld metal and heat transfer are reduced by as much as 75 the strength of the weld remains relatively uncompromised.

Hot shrinking is the legendary shrinking method of simply heating up and dashing water for a quick chill. Heating up metal and throwing cold water on it may shrink it a tiny bit but it makes distortion and hard steel. Yes you can heat shrink aluminum too so don t worry yourself that it can t be done. The heat is doing two jobs here.
