How do I create a welding seam

[Stevepd]

I’m converting some fuel tanks into a spray tank. On the real thing on outer surface you can see the welds. Not very aerodynamic but functional none the less. How do I make these seam lines?.

Hmmm, some sort of filler applied through a hypodermic needle?

I've had some success using some very thin stretched sprue, glued into place with copious amounts of liquid cement, and then mashed and gouged into shape with a hobby knife while still soft. Experiment on a spare if you can, before going live!

A lot of armor modellers discuss this kind of thing, they, from my readings use a method described by LSP Kevin...practice is key though.

until someone makes a 1/32 TIG welder...

Or depending on size required:

Tamiya resin putty rolled up into a tiny snake, then progressive toothpick action.

Nice tutorial from Martin Kovac.

There is another method to replicate the very thin weld seams you can find on modern tanks: use masking tape and dissolved putty or surfacer. Put the tape on each side of the future weld. Then spray surfacer or brush dissolved putty. Remove the tapes and clean the edges with a fine sanding sponge. Done!

I have used lead wire, glue it down and then use small chisel to make the weld. Cheers.

Good show, Martinn.  Many thanks.

Probably not kosher to blow my own horn but I made THESE specifically for aircraft weld seams.

Much like LSP Kevin, I use thin stretched sprue or rod glued on with Tamiya extra thin and then soaked with more extra thin. Before it dries, to get the weld seam effect I use a wooden cocktail stick with just the very tip cut off, pushed into the sprue all along the seam. I have used this quite effectively on 1/35 Churchill tanks.
