Welding & Surface Preparation
Correct use of equipment and competence among users are key factors to safe welding. Safety must always be of the highest priority - for the protection of crew, ship and cargo.
With the Unitor™ range, every welding application on board has an effective solution. 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
These are the only welding machines in the market designed specifically for the maritime industry. Some of its groundbreaking features include a Total Protection (TP) function that automatically shuts down the machine to prevent damage caused by voltage peaks or electricity supply failures. Furthermore, the machine's Voltage Reduction Device (VRD) function limits open circuit voltage to a range of 9-13V, preventing accidents due to electric shock. Both these new enhancements promote safe welding on the vessel.
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 regulations to make sure that our equipment remains compliant always. The Unitor™ range of consumables is comprehensive and production is done in accordance to the four big class societies (DNV GL, ABS, LR, BV).
Global availability in 2,200 ports
It is 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 2,200 ports we service through our global network.
Structured training programs for the crew
On-board welding takes place under varied, daunting and even unpredictable conditions, and the range of base materials that require cutting or welding is typically very 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 crew.
Documentation - a prerequisite for safe welding.
At every opportunity, we offer support to ascertain 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.

We offer you a yearly safety inspection survey of the welding equipment onboard. The welding safety inspection service is a confidential assessment of the safety and operational conditions of electric arc and gas equipment onboard your vessel.
The Unitor range of Air Tools and Workshop Equipment offers you a complete range of power tools you need on board your vessel for the everyday maintenance and repair tasks. We offer a range of Low Vibration Air Tools for the operator's safety when performing needle and chisel scaling, reducing the risk of developing HAV’s (Hand Arm Vibration Syndrome) due to exposure to High Vibration levels.
Our Unitor range of cold repair compounds and stop leak products are absolute necessities on board your vessel for emergency repairs. This allows you to make necessary repairs even when the base material is not weldable in areas you cannot perform hot work, or when you simply do not have the possibilities for rigging up in traditional welding.
Unitor offers 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.
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.
Our Unitor regulators and flashback arrestors provide you the comfort of a steady gas flow while delivering the safety you need. Our lifting-certified transportation solutions and its range of accessories for gas cylinders, gas welding and cutting equipment ensures you a safe transportation of cylinders all over the vessel.
Welding at sea carries a range of safety hazards—not least the ever-present risk of electrocution. The good news is that electrocution injuries are completely avoidable with the right safety precautions. Let's look at some common mistakes that heighten electrocution risk, and how welders can take steps to stay safe.
With the new RISQ 2.0 update, pressure regulators and flashback arrestors must be inspected annually and replaced every five years after the manufacturing date to prevent degradation and leakage. When was the last time you conducted an inspection? Find out how you can stay compliant.

Arc welding processes commonly used by vessel crew, such as TIG and MIG/MAG welding, require the use of a shielding gas primarily to shield and protect the molten weld pool from the surrounding atmosphere. Let's examine the key factors to consider in selecting the right shielding gas for your crew's welding needs on board.
Safety measures when connecting oxygen cylinders to freestanding regulators or high pressure slings in Gas Distribution Systems (GDS)
One of the important skills required onboard is a good command of modern welding techniques. The Unitor Welding Handbook provides guidance in modern welding and related processes and provides the maritime welder with a source of practical information on the right solution to specific onboard welding problems.
Safety measures are crucial for all use of oxygen and acetylene onboard a ship – get to know our various tools, accessories and safety equipment related to gas and cutting solutions onboard.
Do not operate equipment for welding or related thermal processes unless you are thoroughly familiar with the process, the equipment, rules and regulations related to the process and equipment; including proper use of accessories. Preparation for hot-work onboard should include, without being limited to, the points in this checklist to ensure safe operation.
With offices in 75 countries supporting our non-stop operations in 2 200 port locations across the globe, you can be assured that we have the local knowledge and industry expertise to find the best solution to cater for your needs.Contact us
