NS-EN ISO 14744-1:2000

The main purpose of this standard is to provide requirements for acceptance inspection of electron beam welding machines preferably when first installed on the user's premises. This standard can (in full or in part) be referred to in contracts for supply of electron beam welding machines. Further tests are not normally required if proof of satisfactory welding results is provided in the form of routine inspection documentation. However, the requirements of the standard can also be used for inspection as part of maintenance, if required by contract. If modifications are made to an electron beam welding machine (rebuilding, repairs, modification to the operating conditions etc.) such as may have an effect on the acceptance inspection, repeat tests can be necessary covering the machine parameters affected by such modifications. If a welding machine that has already been accepted is dismantled (e.g. in order to change its location), such tests would involve verification according to the requirements in clauses 4, 6.2 to 6.4 and 7.
