The effect of forced cooling using heat sinks on the mechanical properties and interpass waiting time of two-pass welds has been studied for a martensitic steel with a yield strength of 960 MPa Effect of the welding heat input on residual stresses in Nov 01, 2009 · Heat input is an essential factor in quality control in arc welding. It is an important character because like preheat and interpass temperature, it influences the cooling rate which affects the mechanical properties and micro structure of the weld and HAZ, and consequently affects the residual stress distribution in the object . Haynes 230 Tech Data - High Temp MetalsPreheating, Interpass Temperatures and Post-Weld Heat Treatment Preheat is not usually required so long as base metal to be welded is above 32°F (0°C). Interpass temperatures generally should be low. Use high speed steel M-33/M-40 series(6)/or T-15 grade* Speed:10-15 surface feet/minute (200 RPM maximum for 1/4 in. diameter or smaller)

A second preheat at Hotfoil-EHS Industrial Heating, Welding, and Heat Treating For most preheating, post heat treating, and interpass heating, precise temperature control isn't required. Its more important to maintain a minimum temperature, and stay within an acceptable range during the actual welding process, as well as during cool down. Exceptions are with tempered steels.
It is very important to understand the material characteristics of the metals being welded, and know minimum and maximum preheat temperatures, particularly in tempered steels. For most preheating, post heat treating, and interpass heating, precise temperature control isn't required.

Oct 23, 2001 · These properties are specified for the flat-rolled products (plate, sheet, and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications. Composition. Typical compositional ranges for grade 321 stainless sheets of steel are given in table 1. Weldability of Materials - Stainless Steel - TWIpreheating to around 200 to 300 deg. C. Actual temperature will depend on welding procedure, chemical composition (especially Cr and C content), section thickness and the amount of hydrogen entering the weld metal; maintaining the recommended minimum interpass temperature. carrying out post-weld heat treatment, e.g. at 650-750 deg. C. Welding of Special Steels ::Total Materia ArticleVarious steel companies make different proprietary alloys that all have similar properties and, in general, similar compositions. Most AR steels are high-carbon steel in the 0.80-0.90% carbon range; however some are low carbon with multiple alloying elements. These steels are strong and have hardness up to 40 HRc or 375 BHN.
