What Is a Welding Magnet?
A welding magnet, also known as a magnet holder or mag hold, is a jig equipped with a magnet to hold materials in the correct position during welding. It is particularly useful when handling heavy materials or performing detailed work where one-handed operation may lead to instability, burns, or pinching.
Welding magnets enable the secure positioning of two metal materials at a fixed angle, freeing both hands of the welder for safer and more efficient work.
Uses of Welding Magnets
Welding magnets are commonly used in welding and assembly work to hold multiple metal materials at specific positions and angles. They are versatile and suitable for applications where heavy materials are challenging to hold manually or precise alignment is required. Depending on the product, they can hold materials at various angles and even accommodate round pipes and rods.
Beyond welding, they are also useful for temporary holding during metal material processing and assembly, serving as simple magnet holders.
How to Select Welding Magnets
When selecting welding magnets, the range of angles they can hold is a crucial consideration. Products offering a wide range of holding angles are generally more versatile. However, for large components or multi-angled products, usability may be affected by the position of the angle.
The type of magnet is another important factor. Standard welding magnets typically feature a strong permanent magnet attached to an outer frame made of iron or aluminum. Challenges with these magnets include difficulty in positioning, removing after welding, fine-tuning alignment, and the risk of attracting magnetized debris like iron powder.
To address these issues, there are electromagnet-based welding magnets with switches to turn the magnetic force on and off as needed. Additionally, it’s important to consider the weight capacity of the magnet, as using a magnet with a lower holding weight than the material’s weight can increase the risk of accidents.
