welding two pipes together with two arrow fixed multi angle weld clamp magnets and an arc welder Weld clamp magnets work by holding two pieces of ferromagnetic material at different angles whilst they are tack welded together.
Wonkee Donkee says "A ferromagnetic material is a term for anything attracted by a magnetic force. To be ferromagnetic it must contain a element of iron, nickel, cobalt, or gadolinium"
Magnetic force of a 90 degree weld clamp magnet towards a metal pipe The pull force of the magnets within the weld clamp magnet attracts the ferromagnetic material to the magnet holding it in place.The larger the pull force of the weld clamp magnet, the more material it can hold. This is because pull force refers to the limit of holding power a magnet has.

The pull force of a magnet is not determined by its overall size. This means that a large magnet does not necessarily have a larger pull force than a small magnet.

A magnet’s pull force is determined by a number of different factors, see page How does a magnet work?

Labelled groove on a variable angle weld clamp magney Grooves on some of the weld clamp magnets provide extra grip for different shaped metal e.g. round pipes. They provide extra grip by extending the magnet’s pull force to the tops of the grooves. This gives the magnet a greater surface area of the shaped metal to hold onto.
