Yakuji Nippo. In some arc welding processes, e. MMA, the welder controls the process through his experience and measurement of run out length is used to monitor the heat input. However, in is other arc welding processes the quality of the weld depends upon accurate and repeatable setting of parameters such as current, voltage, speed, gas flow, pulse characteristics, etc.

This standard sets the reference level for the accuracy and consistency of the welding output.

EN cu derives its specification for performance accuracy from the requirements of manual welding. In manual welding the welder plays a key role in adapting and adjusting the output of the me equipment to meet the requirements of the weld. This adaptability allows equipment to be constructed with a relaxed specification for calibration of output.

Mechanised welding methods lack the skilled adaptability of the manual welder and require nt precise control of all aspects of the welding process. The control of the output of the welding equipment is of particular importance. Manufacturers have responded to this need by is producing equipment with an accuracy of output control and calibration, which exceed the requirements of EN In addition to the demands of mechanized welding, manual welding methods have become more refined and welding procedures often call for the precise control of power source outputs to limit the freedom of the manual welder in order to produce particular results.

This is a commonly accepted term for this checking operation but it does not meet the strict definition of the word calibration. The operation of calibration can be applied only to determining and adjusting the errors of a measuring instrument. An item of ra welding equipment is not a measuring instrument though the meters fitted to the welding equipment are and can be calibrated.

The difficulty of terminology and the checking task is ted further compounded as many pieces of welding equipment do not have calibrated outputs but are scaled in arbitrary units. Again this is a function of the manual welding usage in which the skill of the manual welder is used to adjust and set the welding variables.English Select a Language: BS EN B11 Standards Inc.
