Over deze norm
|Commissie||Lassen en verwante processen|
Covers the principles to be observed in the approval testing of welder performance for the fusion welding of nickel and nickel alloys. The term "nickel" stands for nickel and weldable nickel alloys. The quality of work involved in welding depends on the skill of the welder to a high degree. The ability of the welder to follow verbal or written instruction and testing of his skill are therefore important factors in ensuring the quality of the welded product. Testing of skill to this standard depends on welding methods in which uniform rules and tests conditions are complied with, and standard test pieces are used. This standard applies to processes where the skill of the welder has a significant influence on weld quality.
