Resistance welding

Lebronze alloys and Laska pay great attention to the process of continuous improvement of their offer. Thanks to close cooperation with automotive manufacturers and implemented research and development programmes in Le bronze alloys, a dedicated and patented production process for Powerode® electrodes was developed.
Very high quality and very high purity, Powerode® alloys offer greater advantages than electrodes from standard CuCr1Zr alloys.

Increasing the number of welds before and between milling

The Powerode® self-protecting layer prevents damage to the electrode surface, which reduces the amount of material to be removed during the milling process.

 

The number of welding points is measured for each type of electrode cap, we take CuCr1Zr as a standard.
The graph shows that Powerode® electrodes have more welding points than standard electrodes.

 

Tests conditions:
I constant: 9,600 A
Steel: XSG 0,7mm / 0,7mm galvanized 10 µm
Protocol: welding point is accepted if dia >4 mm. No intermediary dressing
All tests have been performed by IMATB laboratory of UBS university (France).

Stable, repeatable and enhanced results 

High stability and increased number of points between milling for Powerode® alloy, compared to standard CuCr1Zr electrodes, even after exceeding 2,000 welded points.
