PLASMA ARC WELDING: DEFINITION, WORKING, EQUIPMENT, APPLICATIONS, ADVANTAGES

Plasma arc welding is an arc welding process using heat produced by a compressed arc between a tungsten non-consumable electrode and another workpiece (transferred arc process) or water-cooled constricting nozzle (non-transferred arc process). The plasma is a gaseous mixture of positive ions, electrons, and neutral gas molecules. The transferred arc process produces plasma jets of …

What is A Punch? Punch Principle, Type, Material Introduction

Punching is a common method of metalworking that can be used to transform metal materials into desired shapes, sizes or other properties. Through the punching machine, various complex metal parts can be produced, which greatly improves the production efficiency of the product. Over the past ten years, as the punch presses have become more functional, …

Ultra-High-Power Fiber Lasers Change the Competitive Landscape of Cutting

With the introduction of kilowatt-level fiber lasers in the early 2000s and their subsequent integration into cutting tools in the late 2000s, fiber lasers have transformed laser cutting from a niche method to a mainstream fabrication process. Since then, fiber lasers have dominated the laser cutting of sheet metals because of their ease of integration, …

Punching and Shearing

The term punching is generally understood to include all operations of cutting out blanks from sheet metal The shape cut away is known as the blank, whilst the unavoidable amount of metal sheet left afterwards is only fit for scrap. Some ingenuity is required to so arrange the sequence of successive punchings that the amount …
