AWS- ISO 14744-4-2000, ISO 14744-4:2000, Welding -- Acceptance inspection of electron beam welding machines -- Part 4: Measurement of welding speed
This standard is intended for use when the welding speed for electron beam welding machines complying with EN ISO 14744-1 is to be measured in connection with an acceptance inspection. It provides essential information on the procedure and apparatus to be used for making the measurements.Alternative standardised procedures can be used, provided they have at least the same acceptance inspection as the welds specified in this part 4. The measured parameter is the speed of the translational and rotational movements required to perform the welding operation.The welding speed is one of the significant parameters in electron beam welding. The workpiece or the weld point shall thus be moved at a uniform speed, in a reproducible manner, within given short-term and long-term limits. The purpose of the measurement is to check whether the variations in welding speed are maintained within these limits. This title may contain less than 24 pages of technical content.
API-M:2008 Study Guide for API Standard 1104, Welding of Pipelines and Related Facilities contains information on the use of API Standard 1104, Twentieth Edition, which will assist the student in preparing for using the standard as well as preparing for code-related examinations. Material is provided for each of the 13 sections of the standard and both appendices. Exercise questions and answers are provided for each topic. ISBN 978-0-87171-160-1
