Interpass temperature is the maximum temperature a weldment should be allowed to reach between weld passes. If a pass is completed and the temperature is in excess of the interpass, it should be allowed to cool before continuing.
IBR, or Interpass Temperature and Welding Procedure Specification Review, refers to the control and monitoring of interpass temperatures during welding processes. Maintaining appropriate interpass temperatures is crucial for preventing defects and ensuring the integrity of the welded joint. Proper IBR practices help in achieving the desired mechanical properties and avoiding issues such as cracking or distortion in the weld. It is part of the overall quality assurance in welding operations.
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.

It depends on the resistance to the current flow
The arc is considered to be in the 5,000 o F range. 5,000 degrees Fahrenheit.
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.

Some materials have to be heated before you start to weld on them. They will probably have a maximum interpass temperature, and may also need to be kept heated to a specific temperature for a certain amount of time after you stop welding (called post heat).
The interpass temperature should be checked in the area of the weld joint, particularly on the base metal adjacent to the weld. This ensures that the material is within the specified temperature range to avoid issues such as hydrogen cracking or poor weld quality. It is essential to monitor the temperature between passes during multi-pass welding to maintain consistency and integrity in the joint.
150 degree. When I was involved with submarine construction the metal was preheated 150 F to 200 F depending on the thickness. Interpass temp was 300 F max.
how do you calculate welding electrode consumption
To calculate the preheat temperature for welding, you typically consider the base material's thickness, carbon content, and the type of joint being welded. A common approach is to refer to welding specifications or industry standards, such as those from the American Welding Society (AWS) or the American Society of Mechanical Engineers (ASME), which provide guidelines on preheat temperatures based on these factors. Additionally, the presence of any specific alloying elements and service conditions may influence the required preheat temperature. Always ensure to follow the manufacturer's recommendations and relevant codes for precise values.

Acetylene is commonly used in welding with oxygen to create a high-temperature flame for cutting and welding metal.
A Welding Procedure Specification (WPS) is a formal document describing http://www.answers.com/topic/welding procedures. According to the http://www.answers.com/topic/american-welding-society-1 (AWS), a WPS provides in detail the required welding variables for specific application to assure http://www.answers.com/topic/repeatability by properly trained http://www.answers.com/topic/welder and welding operators. The American Society For Mechanical Engineers (ASME) similarly defines Welding Procedure Specification (WPS) as a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements.
