The research project will play a technical support standard-setting role

"Energy efficiency of electric arc welding," included in the State Administration of Quality Supervision special projects research and public service sectors
      Restricting the energy issue has become an important factor in economic development. Energy saving is an important part of energy work, welding metal welding processing field as a major energy-consuming electrical equipment, improve the energy efficiency of welding energy-saving products and accelerate the popularization and application has become an inevitable trend. To this end, the National Standardization Management Committee appointed by GB General [2008] No. 154 "On the third batch of national standards issued in 2008 Plan for the Amendment Notice" issued a mandatory national standard, "arc welder Limited values ??of energy efficiency evaluation value" development of the project and requested the end of 2009, the project number 20081230-Q-469.
