<\/a>The application of controlled electrical pre-heat is essential for metals having a substantial thickness, complex geometry, critical process or an exotic alloy content. A controlled electrical pre-heat prior to, and concurrent heating during, welding is critical for the purpose of reducing various conditions and properties in the metal. These conditions, if not treated, can often lead to costly repairs during fabrication and unsatisfactory results of the welding process.<\/span><\/strong><\/p>\n\n\t\t<\/div> \n\t<\/div> \n\t\n\t\t\n\t\t\t![\"3\"](\"https:\/\/thermotest.com.my\/wp-content\/uploads\/2014\/10\/31.png\")

<\/a>Post Weld Heat Treatment also known, as \u201c stress relieving\u201d is a process carried out in order to increase the duct ability and elasticity of metals after welding, the material strength of the treated metal is also generally significantly enhanced by the use of a correct heating process. PWHT s also used in order to reduce the chance of corrosion attack that can be induced by chemicals and severe service conditions. This is achieved by removing residual stress form the welded area that would otherwise be susceptible to fatigue corrosion and residual stress fracture. .<\/span><\/strong><\/p>\n\n\t\t<\/div> \n\t<\/div> \n\t\t<\/div> \n\t<\/div> \n<\/div><\/div>\n\t\n\t\t\n\t\t\t\n\t<\/span><\/span>\n\t\t<\/span><\/span>\n<\/div>\n\n\n\t\n\t\t\n\t\t\tElectrical Methods of PWHT<\/span><\/h2>\n\n\t\t<\/div> \n\t<\/div> \n\t\t<\/div> \n\t<\/div> \n<\/div><\/div>\n\t\n\t\t\n\t\t\t\n\t\n\t\t\n\t\t\t
