PEB Fabrication : Reliable SAW Flux Performance in Open-Shop Small Scale PEB Fabrication Unit

Small scale PEB fabricators using trolley-mounted SAW machines often work in open sheds where:

• Weld joints are not perfectly cleaned
• Residual tack-weld slag remains in the joint
• Base metal and wire are prone to rust
• Job alignment varies due to manual handling

These conditions usually lead to unstable welding and poor slag behavior when conventional fluxes are used.

Flux Approach

AV EZEWELD 19 is engineered to perform reliably under such shop-floor realities, allowing stable welding on the shop floor.

Welding Setup

• Machine: Trolley-mounted SAW
• Joint: Fillet weld
• Position: 1G (base table inclined at 45°)
• Weld Speed: 500 mm/min

Consumables

• SAW Flux: AV EZEWELD 19
• SAW Wire: EM12K – 3.15 mm

Video Observation

The customer video demonstrates smooth welding performance despite surface rust, tack-weld slag, and inclined joint positioning. Slag formation remained controlled and detached cleanly, producing a uniform fillet profile.

Result

The customer achieved consistent weld quality with minimal rework, validating AV EZEWELD 19 as a dependable SAW flux for trolley-mounted welding machines used in PEB fabrication.
