Plate was pre machined and shaft was also with a v groove on plates and a step on shaft for correct positioning. I pre heated the 1045 between 450 to 500 degrees or so. The customer was happy with the weld quality but I was not. I had undercut on my top side of each weld.sp.info 5 Methods to Determine Preheat Temperature | WELDING …One important thing to keep in mind is that this method assumes that the steel will reach maximum hardenability, so the value calculated for preheat may be too conservative (too high) for low carbon steels. To see how these methods can vary we determined the necessary preheat for making a fillet weld on two 1.75-inch thick ASTM A572 Gr 50 plates.
