Title: Innovations in Metal Joining: The Contributions of Henri Pajukoski

Introduction

Henri Pajukoski, a distinguished inventor based in Kangasala, Finland, has made significant strides in the field of laser welding. With a total of three patents to his name, he has demonstrated a remarkable ability to innovate and improve efficiencies in metal joining techniques, particularly through the use of spiral laser welding methods.

Latest Patents

Pajukoski's latest patented innovations include advanced spiral laser welding methods for joining metal components. These laser welding techniques focus laser radiation onto the first metal sheet, which may have one or more intervening metal sheets. The innovation lies in the ability for the laser radiation to trace a spiral path, allowing for precise spot-welding of the metal parts. This method utilizes a center beam and an annular beam to ensure the stability of the keyhole during the welding process.

One notable method is designed specifically for welding aluminum parts, especially those with high gas content or dissimilar compositions. The laser traces an outward spiral path before transitioning to an inward spiral path, with the center beam being pulsed at certain intervals during the inward spiral. Another method focuses on welding steel or copper parts that have a coating at the interface, tracing the inward spiral path with capabilities to accommodate zero-gap or non-zero gap interfaces.
