OVERVIEW

Hobart Hoballoy 7018-A1 Stick Electrode

The Hobart Hoballoy 7018-A1 is a specialized stick electrode designed for professionals who demand reliability and precision in their welding projects. Packaged in a durable 50lb can, these 3/32-inch electrodes are engineered to tackle the specific challenges of welding 0.50% Molybdenum steel and other low-alloy steels. This makes them an essential consumable for industries where material integrity is paramount, such as power generation and petrochemical processing.

One of the standout features of this electrode is its advanced coating formulation. Hobart has developed this coating to be highly resistant to moisture pick-up, even in environments with high heat and humidity. Moisture absorption is a common enemy in low-hydrogen welding, often leading to hydrogen cracking and weld failure. By resisting reabsorption, the Hoballoy 7018-A1 helps ensure that your welds remain sound, durable, and free from defects like starting porosity.

Versatility is key for on-site maintenance and construction. This electrode performs exceptionally well in both single and multiple pass applications and can be used in all welding positions. Whether you are working on boiler tubes, high-pressure piping, or general structural fabrication involving C-Mo steels, this electrode provides a stable arc and excellent bead characteristics. It operates effectively on both DCEP (Direct Current Electrode Positive) and AC (Alternating Current), giving welders flexibility depending on their power source availability.

Key Benefits:

  • Moisture Resistance: Protects against hydrogen cracking in humid conditions.
  • Specialized Application: Perfect for 0.50% Molybdenum steels used in high-temperature service.
  • Operational Flexibility: Works with AC and DCEP in all positions.
  • Quality Weld Deposits: Reduces porosity and ensures strong, X-ray quality welds.

FAQ

E7018-A1 electrodes are primarily used for welding carbon-molybdenum steels (approx. 0.50% Mo), which are common in high-temperature applications like boilers and pressure piping.

Yes, as a low-hydrogen electrode, it should be stored in a holding oven after opening the hermetically sealed can to prevent moisture absorption.

Yes, this electrode is designed to operate on both AC (Alternating Current) and DCEP (Direct Current Electrode Positive).

These electrodes have a diameter of 3/32 inches.

Moisture in the coating can introduce hydrogen into the weld pool, leading to hydrogen-induced cracking (cold cracking) and porosity, especially in alloy steels.

This product comes in a 50lb can.

Yes, the 7018-A1 is an all-position electrode, suitable for flat, horizontal, vertical, and overhead welding.

It is widely used in power generation, petrochemical, and construction industries for boiler and piping maintenance.
