Method for spraying welding-rod materials on electric arc wire, involves supplying compressed gas towards base substrate at high speed

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method where welding-rod materials are melted and sprayed onto a base substrate using a combination of electric arc heating and a high-speed jet of compressed gas. The melted metal from the rods is propelled by the gas onto the substrate, forming a coating or layer on its surface. A special nozzle delivers the gas between the contact pipe and the voltage source to direct the spray precisely.

Patent Abstract

The method involves supplying the welding-rod materials (3) to a base substrate (1) through a contact pipe (4). A nozzle (7) is located between the contact pipe and voltage source (5), for supplying compressed gas towards the base substrate at high speed. The ends of welding-rod materials are melted by a voltage source. The melted welding-rod material is sprayed and coated on the surface (1a) of base substrate corresponding to the supply of high-speed compressed gas from nozzle. An independent claim is included for device for spraying welding-rod materials on electric arc wire.
