how to solder galvinized steel

all you need is a torch (i used propane), a grinder (i used a bench top my great grandpa modded with a bigger motor), 40/60 acid core solder and a perpose for the joints. the joints are extremely strong, some how solder is always stronger/harder than the material being soldered. i must have put about 70 pounds of pressure each time i slammed it and about 125 pounds when i pressed on it. these joints are just as strong as brazed joins but cost alot less. perfect for custom rc's,displays or abstract art.

Is that like a "bernzomatic" torch or is it a propane+oxygen torch?

[dippst]

@ihoppy its a direct mount head. no oxy. just thread the nozzel onto the bottle.

what kind of solder should I use and would be best for sheet metal? Cause I want to shave my door handles on my truck

[dippst]

@pinktacoinvaider i used radiator repair solder, you can get a pound of it for $12 at the hardware store. this works well on sheet metal.

@dippst  do you have to use flux with it or is it a flux core?

[dippst]

@pinktacoinvaider the acid acts as the flux. all flux does is keep air out of the joint for a stonger joint.

[dippst]

solder is for copper, brass, steel and any other metal it well stick to. at the time all i had was solder and a propane torch. i now own a fcaw welder.

[iworkforme]

solder is for copper u should braze or weld iron.

[KevinMillard68]

yes you can use electronics solder but you will have to use the flux as well and make sure the parts are clean other wise it wont hold well

one day i might actually care.
