AI Technical Summary
Technical Problem
Existing welding torches stabilize arcs by increasing the ejection amount of expensive shielding gas, which can disturb the gas jet flow and increase costs.
Method used
A welding torch design with a gas diffuser and orifice that ejects shielding gas through staggered rows of holes, allowing for uniform gas flow without increasing the gas amount, using a nozzle with a tapered outlet to enhance arc stabilization.
Benefits of technology
Stabilizes the arc while reducing the amount of shielding gas used, improving shielding performance and reducing operational costs, with a more uniform laminar gas flow and enhanced arc stability.

Abstract
In welding torches, the amount of shielding gas ejected is suppressed while stabilizing arc generation. [Solution] The torch 100 comprises a gas diffuser 32, an orifice 35, and a nozzle 36. The gas diffuser 32 has three rows of holes 32a, 32b, and 32c arranged in a circumferential direction, each at different positions in the x-axis direction of the gas diffuser 32, and the holes 32a, 32b, and 32c of the gas diffuser 32 are arranged in a staggered pattern in the x-axis direction. The orifice 35 has two rows of holes 35d and 35e arranged in a circumferential direction, each at different positions in the x-axis direction of the orifice 35, and the multiple holes 35d and 32e of the orifice 35 are arranged in a staggered pattern in the x-axis direction.
