Painting vs Coating : Difference between Painting and Coating, Which one is best ?

Painting vs Coating / Difference between Painting and Coating Due to no clear definition for any term in the regulations and standards, the names are frequently used interchangeably. The term “painting specification” has traditionally been applied to industrial applications. However, many end-users are currently altering the title of their specification to “Protective Coating Specification” or … Read more

Intermediate Stress Relieving ISR: Where is it Required, Difference between DHT and ISR

Intermediate Stress Relieving ISR Heat treating a subassembly in a furnace to a specified cycle after critical constrained weld joint / joints have been completed without allowing the welds to cool below the pre-heat temperature. The rate of heating, soaking temperature, soaking time, and rate of cooling are all affected by the quality and thickness … Read more

Dehydrogenation Heat Treatment (DHT): Importance, Benefits, Cr-Mo-V Requirements

Dehydrogenation Heat Treatment (DHT) or Post-heating Dehydrogenation Heat Treatment (DHT) is a treatment utilised specifically when welding or preheat is paused or stopped during the fabrication cycle or PWHT is not done immediately due to further fabrication requirements. It is usually done at 300-350 °C [600 – 650˚F (min 570 ˚F)]. Very common and used … Read more

Preheating and Interpass Temperature: Importance, Benefits, Effects on Properties

Preheating Before beginning welding, heat the weldment to a minimum predetermined temperature and maintain it throughout the welding process is called preheating. Preheating is the process of elevating the temperature of the parent material on both sides of the joint to a temperature that is higher than ambient. Preheat is normally required by the relevant … Read more
