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 []Welding Hardox and Weldox - AE Mach** Interpass temperatures of up to approx.400 hs 400 steel preheat and interpass heat weight#176;C can be used in certain cases for Weldox 700960 and for Hardox HiTuf.In such cases,use WeldCalc.Note The table is applicable to single plate thickness when welding with a heat input of 1.7 kJ / mm.Welding Hardox and Weldox - AE Mach** Interpass temperatures of up to approx.400 hs 400 steel preheat and interpass heat weight#176;C can be used in certain cases for Weldox 700960 and for Hardox HiTuf.In such cases,use WeldCalc.Note The table is applicable to single plate thickness when welding with a heat input of 1.7 kJ / mm.

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.
