  • AR400 Welding & Machining Associated Steel Corporation

    A preheat and interpass temperature of 250°F to 350°F is generally sufficient, (350°F to 450°F for 500BHN Plate). Exact furnace controlled temperature is not required, a heat crayon should suffice. When using a torch, move rapidly and evenly to provide a general increase in temperature. Maintain preheat temperature during weld.Read More

  • Why is Preheating Necessary? WELDING ANSWERS

    Preheating steel before welding is common practice. Sometimes we apply heat after we are done welding as well. Other times we apply heat between passes to maintain the minimum interpass temperature. Many use preheat simply because it is written in the WPS, but not really understand why it is necessary. Preheating is used for []Read More

  • Arc Welding 101Measuring preheat and interpass

    Mar 24, 2017 · A typical structural steel welder or weld inspector should keep crayons rated at 150 F, 225 F, 300 F, 400 F, and 450 F around at all times. (It's hard to keep the 32 F, 50 F, and 70 F around, even in my neck of the woods!) I use a rosebud torch to heat my weldment to the proper preheat temperature and strike the appropriate crayon onto the surface.Read More
