ALCAVIL

The Origin

ALCAVIL was founded in in Monterrey, when a group of field engineers identified a systemic flaw in the automotive supply chain: suppliers were delivering electrodes with metallurgical inconsistency and poor machining tolerances, causing unscheduled line stoppages.

What We Do

We are not intermediaries. We are a machining workshop specialized in resistance welding consumables, understanding the needs, flows, and standards this process demands. We integrate the value chain by directly importing certified raw materials to guarantee traceability from foundry to your assembly line.

Quality

Every electrode we manufacture meets RWMA/AWS J1.3 specifications. We work with Class 1, 2, and 3 alloys per AWS J1.3 to satisfy the requirements of OEM, Tier 1, and Tier 2 in automotive, aerospace, and appliance sectors.

ALCAVIL ACADEMY

Technical resources on resistance welding and material selection per AWS J1.3 standard

Technical Guide

MFDC vs AC: Which copper to use?

MFDC (Medium Frequency DC) welders generate shorter and more concentrated current pulses than traditional AC machines. This means higher energy density at the electrode, which accelerates thermal wear. Recommendation: For MFDC, always use C18150 (CuCrZr) for its superior softening temperature (550°C vs 500°C of C18200). Per AWS J1.3 standard.

Manufacturing

The importance of forging in Seam Welding Wheels

A seam welding wheel machined from bar has random grain causing irregular wear. Forged wheels have radially oriented grain, increasing service life by up to 40%. At ALCAVIL we manufacture forged wheels in RWMA Class 2 per customer drawing. All our materials comply with AWS J1.3.

Maintenance

Chiller maintenance to extend electrode life

60% of premature electrode wear is due to poor cooling. A chiller with water at >25°C or flow <4 L/min causes thermal softening even in C18150. Checklist: Water temperature 18-22°C, minimum flow 6 L/min, conductivity <300 µS/cm. Electrodes per RWMA and AWS J1.3.
