Heat Treating realigns the molecular structure of a weld producing a more homogenous weld and heat-affected zone. Preheating weld metals assists complete fusion during the welding process and reduces porosity as well as the potential for cracking. Post heating of a weld is utilized to improve machinability. It also provides corrosion resistance and reduces brittleness. TPT utilizes portable heat-treating equipment to provide services such as stress relieving after welding, shrink fitting, preheating for heavy welding projects and preheating of high strength steal that is prone to cracking.
