Welding & Surface Preparation

Correct use of equipment and competence among users are key factors to safe welding. Safety must always have the highest priority - for the protection of crew, ship and cargo.

With the Unitor range, we offer a complete solution for every welding application on board. Safe welding, we believe, is effective welding, and effective welding leads to greater cost control - keeping downtime for repairs to an absolute minimum, and reducing the risks to crew, cargo and vessel. 

All Unitor equipment is designed in full compliance with current safety regulations at sea and we make technical information accessible to end users, helping to ensure that equipment is always used properly and safely. 

Designed specifically for the Maritime Industry

The only welding machines in the market designed specifically for the Maritime Industry - new features added include a Total Protection function (TP) that automatically shuts down the machine to prevent damage due to voltage peaks or electricity supply failures and VRD function (Voltage Reduction Device) which promotes safe welding by reducing open circuit voltage to a range of 9-13V, preventing accidents due to electric shock.

Fully Compliant with Approvals from Major Classification Societies

Manufactured in full compliance with current regulations for maritime use, we constantly look ahead towards changes in regulation to make sure that our equipment remains compliant always. The Unitor range of consumables is complete and production is done in accordance to the four big class societies (DNV GL, ABS, LR, BV).

Global Availability in 2200 Ports

It’s impossible to predict when or where the need for maintenance or repair will arise. But one thing is certain: when it does you need the right equipment at hand in order to get the job done effectively, with minimum downtime. Our standardised welding products can be delivered through one of the 2200 ports we service through our global network. 

Structured training programs for the crew 

On-board welding takes place under varied and often very difficult or even unpredictable conditions, and the range of base materials that require cutting or welding is typically wide. We help you to prepare for this range of challenges through our dedicated training programs in cooperation with our partners around the world, bringing the best quality training to your crews.

Documentation. A prerequisite for safe welding.

At every opportunity we offer support to make certain that Unitor products are used properly and safely. While the equipment is standardised and easy to use, it is also backed up by detailed documentation - user manuals, welding handbooks, consumable selectors, product data sheets, safety data sheets, problem solver wall charts and specialist literature.

    Air Tools & Workshop equipment

    The Unitor range of air tools and workshop equipment, offers you a complete range of power tools you need onboard your vessel for the everyday maintenances and repair tasks. We offer a range of Low Vibrating air tools for safety of the operator when performing needle scaling and chisel scaling, this is to reduce the risk of developing HAV’s (Hand Arm Vibration Syndrome) due to exposure to high Vibration levels.

  • cold-repair-system

    Cold Repair System

    Our Unitor range of cold repair compounds and leak stop products are absolute necessities on board your vessel for emergency repairs. This allows you to make necessary repairs where base material is not weldable in areas you cannot perform hot work, or you simply don’t have the possibilities for rigging up in traditional welding.

  • Arc Welding Consumables

    Arc Welding Consumables

    Unitor offer you a complete range of welding consumables you need for the everyday maintenance welding on board your vessel. The Unitor storing cabinets ensure you have good control of your welding consumables and electrodes. In addition we offer heating cabinets to prevent moister absorption in your electrodes and a mini drier to dry your moister exposed electrodes.

  • Arc Welding Equipment

    Arc Welding Equipment

    The range of Unitor welding and plasma cutting machines are specially designed and made for the maritime environment. With the Total Protection device on the welding and plasma cutters you have reduced the risk of a machine breakdown due to Voltage peaks on board the vessel, and the low open circuit voltage OCV ensures the safety of your crew. We also offer the complete range of safety equipment and consumables for welding.
