Stress relieving is a form of post weld heat treatment. In stress relieving we heat a material to a specific temperature; hold it at this temperature for a specified amount of time in order to reduce or eliminate residual stresses; and then cool it at a slow enough rate to prevent these stresses from redeveloping.

Both hot rolled and cold rolled steels can easily be welded. However, there are differences between the two that will impact which you choose to use. Making this choice depends on several factors such as strength, surface finish, dimensional accuracy and cost. To understand the difference between hot rolled and cold rolled steel and how […]
Have you heard of post weld heat treatment (PWHT)? Of course you have. If you are involved in welding you have definitely heard this term. But what is PHWT? When is PWHT required? What temperature should PWHT be done at? Heat treating of materials can be a very complicated subject, but when it comes to […]
