Heat Treatment

Heat treatment is the process where the metal is heated without letting it reach its molten or melting stage and then cooling the metal in a controlled way to select desired mechanical properties. Heat treatment can either make the metal stronger or more malleable, more resistant to abrasion or more ductile.  

our website Provides a wide range of books that discusses the various types of heat treatment and its affect on the mechanical properties and micro structure of the material and the proper technique to be performed

AWS - Determination Of Necessary Preheating Temperature In Steel Welding

1983

Methods to determine the necessary preheating temperature for the prevention of cold cracking in steel welding include the 1974 British Standard 5135 (Ref. 1) and a procedure described in Japan Steel Structure Construction (JSSC - Ref. 2). However, there is a considerable difference between the necessary preheating temperatures determined by the two procedures.

Preheat  interpass PWHT for low alloy steel

2014

This report examines, in some detail, the preheating, interpass temperature, and PWHT requirements for fusion welding low alloy steels, such as AISI 4130, in order to reduce the risk of cold cracking. Chemistry of AISI 4130 in wt.% is as follows: C, 0.28-0.33; Mn, 0.4-0.6; Si, 0.15-0.35; Cr, 0.8-1.1; Mo, 0.15-0.25; Ni, 0.25 max.; Cu, 0.35 max. In what follows, nominal alloy contents will be used in carbon equivalent computations. The Ni and Cu contents will not be considered here, since they are not common to all US specifications for AISI 4130.

PVP - 65856 - Computational Fluid Dynamics (CFD) Provides Alternative To Conventional Heat Treatment Guidelines

2017

The present study was completed in two phases . The first phase calibrate d the CFD models using temperature measurements obtained from experiments conducted on two different diameter and schedule pipes with several heating band configurations. In this phase, the thermal contact resistance between heating bands and pipe wall was tuned to match computed temperatures to measured results. The second phase expanded on the calibrated models to pipe sizes varying from 6 to 30 inches and schedule 80 to 160 in order to predict necessary heat band widths needed to achieve temperature gradients less than 15°F in the soak band. The prediction models used multiple control zones around the circumference of the pipe. The use of multiple control zones can help reduce temperature gradients and lead to smaller heating band sizes. The results from the prediction phase define optimum heat band sizing to prevent excessive thermal gradients.

Welding Research Council Bulletin - Recommended Practice For Local Heating Of Welds In Pressure Vessels

2000

The framework for this document is based upon the American Welding Society ANSI/AWS D10.10-90, Recommended Practices for Local Heating of Welds in Piping and Tubing. During the process of revising this AWS document, it was recognized that it might be more appropriate to prepare a separate document pertaining recommended practices for local heating of welds in pressure vessels. At the same time, a request was received to prepare a guideline regarding postweld heat treatment of repairs for heavy wall hydroprocessing reactors. This request was made by a joint industry project on aging hydroprocessing reactors. Additionally, for the last several years, an ASME Boiler & Pressure Vessel Code Ad Hoc Task Group on Local PWHT, operating under the Section VIII Subgroup Fabrication and Inspection, has been developing requirements for local PWHT. The confluence of these three activities is responsible for the development of this document. The document in draft form has been circulated for review and commenting by various communities since May 1997. They are: the Pressure Vessel Research Council, ASME Board of Pressure Technology Codes and Standards Task Group on local PWHT, AWS Subcommittee D10P on local heat treating of pipework, and IIW Commission XI on pressure vessels, boilers, and pipelines. During the review and commenting period, a new revision on the requirements (paragraphs UW-40 and AF-410, see Appendices A and B) for local PWHT in Section VIII of ASME Boiler and Pressure Vessel Code was issued in July 1998.
