For some highly stressed pipe applications, removing excess material from the weld bead and then measuring the resulting profile is required to ensure that there is no stress raising sharp edges to promote cracking.
To ensure high-quality weld performance and good fusion of parts, the weld preparation stage requires a manufacturer to be able to control certain factors prior to welding. Most commonly in the pipe industry, the ability to control the rim and machined angle around the diameter of the pipe’s beveled edge helps to determine the pipe to pipe concentricity. Then, this provides a good basis for the weld to react equally without placing unequal strain on either side of the welded parts. ...
