Sustainable Welding
It is becoming ever more important to act sustainably to achieve efficient manufacturing during the welding process. There are many factors that have an impact on sustainability where the welding process is concerned.
Reliable welding equipment
Weld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds by monitoring the oxygen levels when welding sensitive materials such as titanium, zirconium, nickel, stainless steels and low alloy steels containing chromium. Oxidation can lead to loss of corrosion resistance and a decrease in mechanical strength.
Many decades of design and expertise has gone into developing the PurgEye® range of Weld Purge Monitors®. These extremely reliable monitors can measure residual oxygen content as low as 1ppm (0.0001%).
Increased welding speed
Inert gas purging is now the preferred method to avoid contamination during welding. The use of an Inflatable Weld Purging System can reduce purging times dramatically, particularly as tube and pipe diameters increase.
PurgElite® and QuickPurge® are now the industry’s standard inflatable devices. Manufactured from 1” (25 mm) right up to 88” (2,235 mm), these systems reduce inert gas usage and therefore cost.
Creating high-quality joints
The use of Argweld Weld Trailing Shield® can provide inert gas coverage during the cooling process and thus avoid oxidation in high temperature zones. Trailing Shields® simply attach onto any TIG/GTAW, PAW/Plasma and MIG/GMAW welding torch,
For complete inert gas coverage, essential where complex geometry joints are involved, welding inside a Flexible Welding Enclosure® offers the user a further option. The use of Flexible Welding Enclosures® has increased significantly during development of the Wire Arc Additive Manufacturing process, providing a complete inert gas shield around reactive alloy materials.
Reducing costs
By striving for zero colour welds, companies can eliminate any post-weld cleaning costs. These costs can be very high. In some restricted access can even preclude effective post-weld cleaning.
