April 1, 200917 yr I'm really confused about how to scarf in order to forge weld. I'm working on a prodject to make a stove poker. I will get my hands on a pic. of it here pretty soon.
April 1, 200917 yr I guess the first principle is to get enough mass in place, so that when the pressure is applied, the finished product is thick enough, upsetting is the first part. Then creating matching surfaces to align, and then get to stick is the other part.
April 1, 200917 yr The upset is to put material into the area either side of the weld area to allow for wastage and for thinning while blending in the toe of the scarf. The important things for me are 1. Slope to the end of the scarf or you will be left with cracks post welding 2. Thin the toe (end) of the scarf so that it is smaller than the bar too which it will be welded (anvil effect) 3. Weld only when the bars are wet 4. Bars won't weld when 'crusty' 5. Support the bars on the side of the anvil when bringing them together
April 1, 200917 yr Author Thanks! that helped a lot! I saw your video on youtube about forge welding that branch. Great stuff.
April 1, 200917 yr They say a picture is worth a thousand words, thanks for that fantastic 8,000 word essay Mark. Learned heaps from it. Mick
