The measurement of spot-welding current

Electrical Engineering, 1940
CURRENT is an essential factor in the complete specification of spot-welding conditions. Therefore, the need for the measurement of spot-welding currents arises, if optimum conditions determined in experimental laboratories are to be duplicated in production shops. Laboratory methods must be accurate and supplemented by facilities for ready calibration

Current Regulation in Contact Welding

Russian Engineering Research, 2019
Algorithms for current stabilization in the control of contact welding are considered. The proposed method for specifying and maintaining the welding current permits correction of the thyristor firing angle by means of an approximate formula taking account of the measured current-pulse parameters in phase regulation.

Current Research Into Laser Welding Aluminium Alloys

SPIE Proceedings, 1989
ABSTRACT Although welding experiments on light alloys (aluminium or titanium based) have been performed since the beginning of the 1980's, the relative techniques have rarely been applied to production. The major difficulties in laser welding these alloys is only partially due to the differing thermal properties of the materials: another feature of ...

Current Issues and Problems in Welding Science

Science, 1992
Losses of life and property due to catastrophic failure of structures are often traced to defective welds. However, major advances have taken place in welding science and technology in the last few decades. With the development of new methodologies at the crossroad of basic and applied sciences, the promise of science-based tailoring of composition ...
