Benefits Of Hand Welding

Rather than using a bench mounted or special purpose ultrasonic welding machine, ultrasonic hand welding can offer great flexibility, portability and a low cost solution to your joining requirement, with only a basic level of skill required for repeatable results. Let’s discuss hand welding in further detail and examine the main benefits of this method. Understanding The Hand Welding Process In what circumstances would you choose hand welding? Sometimes referred to as manual welding, hand welding is an ideal technique for low or high product volumes where it is not cost-effective to use a larger welding machine, as well as intricate welding tasks in complex geometries where an alternative would be a robot cell welder. They are also commonly used for first or second or operation work when staking multiple points working in conjunction with a multi head machine. Tools are extremely important in hand welding with the correct designed tool ensuring the end welding result is both repeatable and strong. The operator controls the pressure being applied during the process whilst the generator will have a pre-defined timer set. On activation of the welder trigger the ultrasonic’s will start and the material will begin to soften and form, once the ultrasonic’s are complete the operator normally maintains pressure allowing for the weld to cool. The whole process is usually completed within about 3-5 seconds, actual time the ultrasonic’s are activated is normally under 1 second! The final outcome of the weld relies on a combination of well-designed tooling and precision equipment, which is why it is worth investing in both high quality hand welding machinery and market leading training to go with it. There are two main variants of hand welder, straight handle or pistol handle. Both have their own ergonomic advantages and is more often down to the customer on which is preferable for welding there product. We offer both hand welders in either 35 kHz or 40 kHz.
