Efficient Powder Handling for Welding: Patent-Based Solutions
Here’s PatSnap Eureka !
Summary
Problems
Current powder welding technologies face issues with uneven heating of powder, excessive consumption, and uncontrolled mixing of old and new powder, leading to inefficiencies in the welding process.
Innovation solutions
A welding device with heated gas input in powder containers ensures controlled heating and mixing of new and recycled powder, using multiple holes or pipes for even distribution, and separate containers for used and unused powder to optimize powder usage and quality.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If powder is heated in a pressure vessel before distribution, then the powder can be transported to the welding area, but the heating is uneven and insufficient
Why choose this principle:
The pressure vessel is divided into multiple heating zones with separate heating elements positioned at different locations (top, bottom, and side walls). This segmentation allows each zone to be heated independently, ensuring uniform temperature distribution throughout the powder mass and eliminating the uneven heating problem.
Principle concept:
If powder is heated in a pressure vessel before distribution, then the powder can be transported to the welding area, but the heating is uneven and insufficient
Why choose this principle:
Different regions of the pressure vessel are equipped with heating elements tailored to their specific thermal requirements. The top and bottom walls have heating elements oriented perpendicular to the surface, while side walls have heating elements oriented parallel to the surface. This local quality approach ensures that each region receives appropriate heating to achieve overall uniformity.

Abstract
A welding device ( 1 ) for powder welding and a method for powder welding is described. The welding device comprises at least a first container ( 4 ) for fluxing agent in powder form, which first container ( 4 ) comprises an outlet ( 6 ) with an outlet direction ( 7 ) arranged for outflow of powder. The welding device ( 1 ) comprises a first member for inlet of heated gas into the first container. According to the method powder is arranged in the first container. Gas is heated and is allowed to pass into the first container ( 4 ) for heating of the powder. The powder is then fed out on a welding area ( 3 ).
