We are an Authorized Distributor for Luvata, one of the country’s most respected manufacturers of welding electrodes. Luvata has a proven track record of supplying high-quality resistance welding electrodes. Please review the following tables to discover the best copper alloy & cap geometry for your application.
Luvata supplies all sectors of the welding industry with a wide array of products consisting of copper alloys in various shapes, sizes and specifications to meet each customer’s unique welding conditions. Luvata’s resistance welding products are used on robotic welding equipment, primarily in automotive and appliance applications. The unique blend of superior alloy composition and proprietary cold working properties enhance the superior performance of Luvata electrodes in adverse welding conditions created by specialized coated materials.
The Ideal Solution for Resistance Welding Coated Steels
The introduction of galvanised and high-strength steels, as well as a variety of newly developed coatings in automotive manufacturing have created new challenges for the resistance welding industry.
Zinc, higher strength steels, and other coatings can have adverse effects on the performance and life of cap welding electrodes that lead to premature wear and tear, sticking and increased dressing frequency in order to maintain quality welds. As a result, traditional welding with chrome and/or chrome zirconium alloy electrodes has become inefficient and costly.
Luvata’s resistance-welding electrodes have been designed to overcome these challenges and provide the ideal solution for demanding welding conditions.
In today’s resistance welding market, cap electrodes are manufactured from four materials: AL2O3, CrCu, CrCuZr and CuZr.
Products
Z-Trode®
Z-Trode® is the ideal cap electrode for resistance welding of light-to-medium gauge coated and uncoated steels and aluminum alloys.
A-Trode®
Luvata’s A-Trode® is the universal cap electrode for reliable resistance welding of light-to-medium gauge coated and uncoated steels.
C-Trode®
The C-Trode electrode is available in most industry sizes, geometries and tapers; and is cold headed or machined to deliver your custom-made shape.
Cupal®
Cupal® cap is a cold-formed alloy of copper dispersion strengthened with Aluminum Oxide. It is available in most industry sizes, geometries and tapers; and is cold headed to deliver your custom-made shape.
Nitrode®
1.1% AL2O3 in Copper. Dispersion Strengthened Copper C15760, RWMA Class 20. The most cost effective cap electrode available for resistance welding applications.
Nitrode Composite
A welding cap electrode with a Nitrode (C15760) core or insert, and a Z-Trode (CuZr C15000) jacket. Provides the performance of the full-bodied, Nitrode, while reducing the overall cost of welding.
P-Cap
The Luvata P-Cap is a self-dressing electrode that maintains a constant current density across the weld face under typical welding forces. It should be used with either the Nitrode Cupal or Z-Trode materials for the best results.
