Bend test coupons for welding procedure qualification. A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.
In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
The objective was that the same qualifications could be awarded in any country by using a single syllabus for each level of the training course and a harmonized system for examinations. EWF developed a comprehensive and harmonized system for training, qualification and certification of welding personnel and managed its application ever since.
Inspection may be manual, conducted by an inspector using imaging equipment, or automated using machine vision. [citation needed] Since the similarity of materials between weld and workpiece, and between good and defective areas, provides little inherent contrast, the latter usually requires methods other than simple imaging.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
The achievement of this designation represents the initiative to excel beyond the normal requirements for operating a hearing instrument dispensing practice. The designation, BC-HIS (Board Certified in Hearing Instrument Sciences), distinguishes the Board Certificant's outstanding skills and professional expertise needed for completion of the ...
