PWHT stands for Post Weld Heat Treatment, a process used to reduce residual stresses and improve the mechanical properties of welded joints.

• PWHT involves heating the welded component to a specific temperature for a certain period of time, followed by controlled cooling.

• The process helps to eliminate hydrogen cracking, improve toughness, and reduce distortion in the welded joint.

• Common methods of PWHT include furnace he...read more

WQT range refers to the range of values for Water Quality Testing in a specific context.

• WQT range can vary depending on the parameters being tested, such as pH, turbidity, dissolved oxygen, etc.

• For example, the WQT range for pH in drinking water may be 6.5-8.5.

• Monitoring and maintaining WQT range is crucial for ensuring safe and clean water supply.

• Regular testing and analysis of water samples help in determining if the

LPT acceptance criteria ensure that the test results meet specified requirements.

• Test results must meet specified requirements outlined in the acceptance criteria

• Acceptance criteria should be clearly defined and documented

• Criteria may include specific performance metrics or thresholds

• Examples: minimum tensile strength, maximum elongation percentage

The required concrete aggregate crushing value is determined by testing the strength of the aggregate.

• The crushing value should not exceed a certain limit to ensure the quality of the concrete.

• It is typically measured using a compression testing machine.

• The standard limit for aggregate crushing value is usually around 30-45% for concrete used in construction.
