Description of the electrodes
Repeated piercing of the electrodes at a temperature of 350 ° C for 1.5-2.0 hours. The welding coefficient of the electrodes PALB-52U FLAGSHIP is 9-10 g/Ah. The consumption of electrodes per 1 kg of deposited metal in the PALB-52U FLAGSHIP is 1.5 kg.
Scope of application
The PALB 52‑U electrodes from Penzaelektrod have gained the trust of professionals in the field of pipeline construction. Their key advantage is their versatility when working with pipes of different strength classes, which makes them an indispensable tool in the hands of an experienced welder.
Why are these electrodes chosen for pipelines?
- Perfect first pass
The electrodes ensure the perfect formation of the reverse roller, a critical element in welding the root layer. This guarantees:
- tightness of the joint;
- uniform penetration of the edges;
- absence of non-welding and other defects.
Applicable for pipes with a strength class up to K60.
- Reliability of subsequent passes
When filling and lining the seam, the electrodes demonstrate:
- stable arc burning;
- easy separation of the slag crust;
- minimal metal splashing.Gorenje
Suitable for pipes with a strength class up to K54.
Key advantages in the work
- Process control accuracy: the predictable behavior of the electrode allows the welder to confidently form the seam even in difficult spatial positions.
- Saving time: the absence of the need for additional cleaning and correction of defects speeds up the completion of tasks.
- Guaranteed durability: the connections meet the requirements of industry standards for main and industrial pipelines.

Performance characteristics
The PALB 52‑U electrodes demonstrate outstanding versatility and predictable behavior in a wide variety of welding conditions.
Spatial capabilities:
- Acceptable positions: all except top-down welding.
- Vertical welding: confidently hold the arc, ensuring stable seam formation without streaks.
- Welding of small diameter pipes: thanks to controlled heat input, the risk of burns is minimized.
Seam formation quality:
- Reverse roller: the ideal formation during welding of the first pass is a guarantee of tightness and strength of the root layer.
- Controllability of the process: precise parameter adjustment allows you to adapt the seam to any project requirements.
- Break-off welding: the electrodes maintain arc stability during intermittent operation.
- Short arc: Recommended to achieve maximum penetration depth and minimize deformations.
Arc gorenje:
- Stability: Steady gorenje even at fluctuations of current.
- Gentle gorenje: smooth melting of the electrode reduces the risk of defects.
- Low current operation: maintain stability at reduced current levels.
- Versatility of sources: compatible with any DC devices.
Convenience of work:
- Detachability of slag: the slag crust cracks and separates on its own - minimizes labor costs for cleaning.
- Splashing: the spray level is kept to a minimum, which increases the cleanliness of the work area and reduces material consumption.
- Gas emission: moderate, meets safety standards and environmental requirements.
Mechanical properties and standards:
- Compliance with GOST 9466-75: guaranteed strength, toughness and ductility of the welded joint.
- Strength class: suitable for pipes up to K60 (first pass) and up to K54 (subsequent passes).
Recommendations for use:
- Welder's experience: requires qualified personnel to accurately control the process parameters.
- Surface preparation: welding on contaminated areas is not recommended - for a high-quality seam, it is necessary to clean the edges from rust, oil and scale.
