Carbon Equivalent to Assess Hardenability of Steel and Prediction of HAZ Hardness Distribution. A practical method to predict HAZ hardness distribution was studied by considering the effect of prior austenite grain sizes on hardenability and that of tempering. For 400 to 490MPa grade steels, hardness distribution between fusion and Ac 3 lines can be fairly well predicted by introducing the effect of grain sizes to the maximum HAZ hardness prediction Why is Haz more important than weld metal?During the selection of steels, the characteristics of the HAZ are more important than the weld metal. This is since the metallurgical and mechanical properties of the HAZ are directly linked to the selected steel. However, these properties can be adjusted by welding parameters and post weld heat treatment (PWHT).See all results for this questionWhat is the stress rate of a tensile machine?The speed of the cross head of the tensile machine therefore needs to be controlled and BS EN 10002 specifies a stress rate range of 6MPa per second to 60MPa per second. The ASTM specifications have similar - but not identical - requirements. Fig.4. Effect of speed of testing on strength and ductilitySee all results for this question

What is the Heat Affected Zone (HAZ)? - TWI

The heat affected zone (HAZ) is a non-melted area of metal that has undergone changes in material properties as a result of being exposed to high temperatures. These changes in material property are usually as a result of welding or high-heat cutting. The HAZ is the area between the weld or cut and the base (unaffected), parent metal.What is cross joint tensile test?These are generally cross joint (CJ) tensile tests of square or rectangular cross section that, as the name suggests, are oriented across the weld so that both parent metals, both heat affected zones (HAZs) and the weld metal itself are tested ( Fig.1 ). The excess weld metal in the cap of the weld may be left in-situ or machined off. Fig.1.See all results for this questionWhat are the objectives of Weld assessment?One of the objectives of such assessments is to define maximum tolerable flaw sizes and so avoid unnecessary weld repair without compromising the integrity of the pipe. The review focuses on installation and operational conditions that give rise to axial plastic straining in the pipe.See all results for this question

Welding effect on tensile strength of grade S690Q steel assessment and predictions of haz tensile properties of

Feb 01, 2019 · By assuming a constant strength of the entire HAZ, numerical analysis predicted that the tensile strength of HSS butt joints would decrease with the increase of the width of HAZ. Hochhauser and Rauch [ 13 ] found that the width of soft layer ranged from 0.33 to 0.6 times of the specimen thickness, and the reduction of tensile strength of butt joint was 3% to 8% of its original strength.Weld Strength Mismatch and HAZ Fracture Toughness The effect of weld metal strength mismatch on the fracture toughness of the weld heat affected zone (HAZ) in two ferritic steels is described. Mismatch was achieved in two different ways which ensured that the HAZs were the same, irrespective of mismatch level. It is shown that fracture toughness is more affected by the local strength of the HAZ rather than differences in strength between weld metal and parent plate. Where HAZ strength is lower than both the parent plate and weld metal, HAZ fracture tougSee more on twi-global assessment and predictions of haz tensile properties ofThe tensile properties and toughness of microstructures assessment and predictions of haz tensile properties ofIn the transportation of oil and gas products from and over remote locations, such as Canada's Arctic environment, pipelines are used.

In addition to variations of the properties due to the shape of the specimens and the testing temperature, the rate of loading will also affect the results.
