Selection of Ultrasonic Metal Welding Machine and Welding Horn
If the spot welding machine you purchased is used for spot welding of positive electrode (aluminum and aluminum spot welding) in lithium ion battery, due to its low power and other technical requirements, the metal welding machine generally made of plastic welding circuit can be used, and the price is RMB 10,000 to RMB 20,000;But if high quality requirements, or choose professional metal welding machine.
When welding materials such as copper and nickel, professional ultrasonic metal spot welding machine must be chosen. The metal welder that changes with plastic welding circuit still can deal with to proofing process, but want batch production really, that a lot of problem came, the first is production stability.
For different welds and materials, the amplitude is the key, and the lines are the important details.Ultrasonic welding requires amplitudes like a double-edged sword. Too small to be welded, too large to be damaged. This directly requires that the welder must have continuously adjustable amplitudes.
The excellent control mode in ultrasonic metal welding machine is the energy control mode, that is, the energy consumption of each welding.If a device has no energy control mode, it can only be a low-end product, which is not good for quality control.
Welding horn mode selection: the welding horn is divided into two parts: body welding horn and integral welding horn.The split-body welding horn is mostly used by AMTECH, and its rare advantage is low replacement cost, while the rest are all technical shortcomings, such as the heating caused by the difference of sound speed between two materials. From a technical point of view, the integrated welding horn has an unbeatable advantage.
Frame structure problem: the most important one is the way of fixing the welding horn and the second level rod. Metal welding usually faces great pressure and side direction.This requires that the welding horn and the secondary rod fixed way must be hard fixed.What is hard fixed means, namely fixed position is metal to metal to tighten, corresponding is the fixed ring in plastic welding is cushioned with rubber ring or nylon washer, this method is used in metal welding is equivalent to suicide: there is no limit.
Pressure control mechanism: a good welding machine must have a good pressure control mechanism. Electric proportional valves or precision pressure control valves are pressure control valves with feedback, which can control stable air pressure well.
