Why is tip dressing necessary?
During spot welding, the electrode shape changes. Poor current flow, uneven electrode wear, and significantly reduced weld quality are the consequences. Tip dressing restores the original electrode geometry.
What are the effects of an undressed electrode?
It leads to unstable weld spots, increased heat generation, and a shortened service life of the welding tips.
What advantages do automatic tip changers offer compared to manual changes?
Automatic tip changers reduce downtime, ensure consistent change quality, and relieve the operator. Tip changes are reproducible.
When should tip dressing or changing be performed?
When the tip shape deviates from the target dimensions, the weld quality deteriorates, or a specified number of welds has been reached.
⇒ Regular tip dressing and automated tip changing are crucial for stable processes, high weld quality, and maximum system availability – and thus make a significant contribution to efficiency in automated manufacturing.
