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.
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.
machine is the mechanical engine g and aromatically to use it
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).
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.

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.
Wire feed speed in MIG welding is calculated by multiplying the welding current by the wire feed rate. This formula helps determine the speed at which the welding wire is fed into the weld pool during the welding process.
The optimal temperature for using MAPP gas in welding applications is around 3,150 degrees Celsius (5,700 degrees Fahrenheit).
