STRESS RELIEF PROCESS

HEAT TREATMENT

Post welding stress relief heat treatment is an essential process to ensure the removal of stress corrosion cracking (SCC), caused by internal or residual stresses near welds. These can make the areas brittle and susceptable to fracture

Proven Technical Expertise - 

Excel Power Construction have proven systems and technical expertise to ensure metals are able to be heated to high temperatures, as in the case of pipework, so that they can be welded after which controlled cooling using thermal couples is required. All stages of the process require careful temperature monitoring and adjustment.

Stress Relief Process

Careful heating and subsequent uniform cooling is essential, and here at Excel Power Construction, we have years of hands on experience and with the use of thermal blankets, and constant precise temperature monitoring (via thermal coupling), this is achieved to exacting standards.

Where chrome molybdenum steels usually need stress relieving in the 675 to 700°C temperature range it is essential in all cases that a full understanding of the alloying system and previous heat treatment is taken in to consideration prior to commencement of work.

This is a highly complex field of welding and one of our engineering team advisors will be able to assist with any enquiries you have. Call now: (+44) 01656 661188 for free initial advis
