HIGH SPEED, LOW POROSITY

Open the catalog to page 1

High Speed, Low Porosity. When it comes to making automotive parts, productivity and quality are the highest priorities. But those targets can be hard to hit when you’re welding galvanized material with conventional processes. Welding on galvanized is difficult. The zinc coating varies. The fit up varies. Porosity can occur. You’re often forced to make hard choices between proper weld size, faster weld speed or good x-ray quality. Process Z™ gives you all three, without forcing you to compromise. Our Metalshield® Z gas-shielded wire, combined with our patented Rapid Z™ waveform technology...

Internal Porosity Comparisons Process Z vs. Solid Wire Porosity (Area, as % of Total Weld) Process Z Solid Wire 14 The Z Factor: Stronger and Faster, Inside and Out Clean welds, easy coating Travel Speed (in/min) 40 ipm Getting it done right the first time saves time and money on the production line. Process Z’s claim to minimal porosity is borne out in its high x-ray quality. The result is defect-free welds inside and out, and little or no rework. Example X-ray images correspond to data above. Dark spots indicate porosity. A clean surface is always easier to work with. Typically, the...

Process Z It’s Not Just a Wire It’s a System AutoDrive® Robotic Wire Drive Wire Delivery Conduit Metalshield Z wire alone does not allow us to address the trade off between travel speed and porosity. Instead, Process Z is the sum of three key innovations working together to tackle the challenges associated with welding on galvanized material. Rapid Z is a proprietary waveform mode developed by Lincoln Electric to specifically optimize the Power Wave power source. By controlling each part of the welding waveform, the weld’s penetration, deposition and heat input can be optimized. The...

Production-Ready Packaging Metalshield Z wire is available in 500 lb. drums for high productivity applications or 33 lb. spools for direct wire feeder mounting. DIAMETERS/ PACKAGING Wire Diameter in (mm) Part Number Effect of Rapid Z Waveform Smooth, Stable Metal Transfer With Rapid Z Waveform The electrode droplet transfer is focused and predictable. Less of the surrounding zinc coating is introduced into the weld - meaning less internal porosity. Smooth droplet transfer also delivers more stability and less spatter when welding at increased travel speeds. Without Rapid Z Waveform Zinc...
