How To Weld 4140 Steel WELDING ANSWERS

I don’t have a way to measure 650-700 deg. My plan is to build a coal fire in the forge. Place the assembled block of 4140/1018 hardy post in the fire and see the colors. When the block reaches gray, I will assume it is hot enough to weld. The assy. will be placed on a steel plate next to the fire.
