How Heat Treatment Can Affect Welded Joints

Much though engineers wish the opposite were true, heat treatment work can weaken welded joints. Since welding equipment uses thermal energy to fuse parts together and add filer metals, the application of more heat can further alter a weld’s jointing properties. A frustrating fact indeed, especially since heat treatment processing uses an inordinate amount of […]

Common Induction Hardening Problems and Resolutions

Just as a reminder, induction hardening technology is used to enhance the toughness and fatigue resistance of carbon steel parts. Components to be heat treated are placed inside a furnace, around which a copper-wound electrical coil runs. When this induction coil is energized, it generates a strong magnetic field, which “induces” workpiece heat. However, although […]

Risk Management in Heat Treatment

Not every processing pipeline in a heat treatment facility is mechanically oriented. Away from the vacuum-sealed furnaces and quenching tanks, the alloy hardening work is viewed from a different perspective. Surrounded by computers and process viability statistics, a risk assessment team is hard at work. Somewhat ironically, the engineers who’re caught up in this stress […]

Causes of Steel Warping During Heat Treatment and How to Prevent Them from Happening

Ideally, heat treatment work affects the microcrystalline structure of a steel part. In the furnace, then cooled gradually or quenched suddenly, the physical properties of the steel alters. The processed component becomes harder. It also gains a more corrosion-resistant structure. What the high-tensile alloy should never experience is any amount of steel warping. That, unfortunately, […]

Effects of Adding Carbon to Iron during Heat Treatment

Carbon isn’t a metal. Actually, it’s a sooty black substance, and it’s not that strong. However, appearances can be deceiving, as every engineer knows only too well. Crushed by incredible pressures, carbon crystals become diamonds, which are the strongest naturally occurring substance known to man. In light of this most helpful material feature, by diffusing […]
