In intelligent manufacturing, welding is probably one of the most critical processes and at the same time, the most expensive and time consuming operations for factory workers. Choosing the right and proper magnetic welding clamps or welding magnets, can have a great impact on the overall productivity and component quality. Let HVR MAG show you how electro permanent magnets are used typically for demanding and heavy workpieces welding in manufacturing assembly.
Magnetic Welding Clamps in Shipbuilding Assembly
As you can see, these round/circular welding magnets set in rows at each side of the backing plate, in a shipbuilding factory, are specially designed and manufactured by HVR MAG. They are distributed evenly at multiple positions to hold/clamp pieces of materials together tightly. This makes it easier for welders to weld the pieces together in a tight alignment without worrying about movements in the sheets or parts.
Magnetic Welding Clamps in Automobile Assembly
It has been a trend that automotive manufacturing is becoming highly smart & automated. Under that trend, magnetic welding clamps are gaining increasing popularity in the automated robotic welding line.
Electro permanent magnets in the circled area in the picture, are set to hold/clamp the auto frame tightly for the robots to perform welding procedure.
Why Are Magnetic Welding Clamps Used?
Most welding fixtures are specially designed for the assembly process of a certain welding assembly, which is a non-standard device. Welding requires less man-hours, and about 2/3 of the total processing man-hours are used for material preparation, assembly and other auxiliary work, which greatly affects the welding production speed. For this reason, it is necessary to promote the use of magnetic welding clamps in automated welding assemblies, due to the following benefits gained:
(1) Accurate positioning & stable clamping reduce the size deviation of welded parts, and improve the accuracy and replaceability of parts.
(2) Eliminate welding deformations.
(3) Position oriented welding guarantees good welding formability, reduces defective rate & improves welding speed.
(4) Replaces the heavy work of positioning, clamping and workpiece turning required for manual assembly of parts, and improves the working conditions of workers.
Why Choose Electro Permanent Magnets As Magnetic Welding Clamps?
Some may wonder why did the above mentioned factories choose EPMs instead of permanent magnets or electromagnets to hold the welding pieces. The reasons are as follows:
1)EPMs can be instantly switched on/off by connecting electricity and vice versa – beat permanent magnetic clamps which needs to be turned on manually one by one
2)They only need electric power for MAG & DEMAG phase, DO NOT consume electric power when in holding/clamping state, much more energy-saving than electromagnetic clamps
3)Can remain clamping/holding of the piece even in a power failure, no falling parts, safety guaranteed – beat electric type clamps again
