Information about how to get the best from Zeromag, Magmeter and others.

Diverse offer training and on site consultancy for magnetism problems.

Diverse Multi-physics

Diverse offer advanced finite element magnetic and multi-physics finite element analysis capability. Contact us for details.

Diverse manufacture and sell equipment and expertise to overcome magnetic arc blow.  Our robust, portable, high power demagnetizers and magnetic instruments are used by leading welding companies worldwide.  Proven over years with hundreds of installations this technology is used at pipeline laying sites on land or at sea, construction sites and even in smelting environments.

The equipment is available with a range of output powers, and options such as joint degauss, clam coils and bobbins. Zeromag is designed to provide a zero gauss welding environment.  This allows welding that was impossible because of magnetic arc blow to proceed immediately completely unhindered.

Magnetic finite element analysis


Diverse provide a comprehensive training series on-site or on-line for magnetic arc blow. The course is conducted at the customer’s site and training comprises a full day, half of which is theory and half is hands on in the workshop. Successful delegates will be able to solve magnetic arc blow and will receive a training certificate.


“.. without Zeromag we could not have     finished the job” - BP

“.. your equipment saved the project and     effectively saved our company” - FPC

“.. when we tried to weld the gas main - the     field was over 500 gauss, with Zeromag     we controlled it to zero” - FB

“.. because of magnetism we had been     trying to weld for 2 weeks and, within     minutes, with Zeromag we were welding!”     - WBC
