How to Create Accurate Weld Effects
Example 2: multiple butt welds
In this example we shall go one step further and attempt to create a more complex example of welding. In this case we will create a triple butt weld where one weld section has a very different consistency from the others; essentially we will try to create a splatter kind of weld effect.
In the same manner as before we have a butt weld template to which we have
already applied a single weld bead (convex), using the methods as described
previously, see Pic 15. In this example you can see a small run of milliput to
the left of this seam. This is a small roll of milliput I added as a base filler
as I had made the butt weld sections a bit too far apart!
In Pic 16 we have added the second weld seam. These have layered nicely together but as before no final blending is done until the final weld is added as we do not want to apply too much water which could have the effect of dissolving too much milliput and thus ruining the fine detail on the weld ridges.
The next stage is to create a weld seam that has a much rougher surface consistency. In order to make this I have used a product called CAST’a’COAT ® that is available from the Small Shop in the UK. This is a product that consists of sets of granular materials in two grades. The idea behind this product it to replicate the rough surface effects on a variety of materials and surfaces.
In order to create a ‘splatter’ type weld I decided to mix in some of the coarse grained CAST’a’COAT into a roll of milliput before application to the weld area. This can be seen in Pic 17.
Once this was mixed in, and by this I mean the CAST’a’COAT was rolled into the
surface, rolled back into a ball, rolled out again and into more CAST’a’COAT
until I had a nice consistency of material throughout the volume of the milliput
and not just stuck to the surface.
The weld was then applied to the sectional surfaces but this time was detailed with a toothpick as I did not want to create a ridged effect here. The toothpick was gently pressed into the weld surface and a certain amount of material was picked out to the sides in order to simulate a very messy process indeed. The end result prior to water blending can be seen Pic 18. The final result looks very rough but even at this stage the splatter weld has a very rough feel to it surface that with correct painting/washing etc will dramatically bring out the detail.
A good example of the effect I was trying to achieve here can be seen below (again from an SU100). We can see very clearly the triple weld with different consistency effects. In hindsight I should have created the example above actually in the gully of the template I used for this example as it would have shown to much better effect the weld join across the entire flat surface.
