Abstract
Official abstract text for this publication.
A welding method, which performs non-keyhole welding of a ferritic stainless steel having a plate thickness of 3 mm or less using a plasma welding torch ( 10 ), includes supplying an inert gas, as a pilot gas ( 23 ), into the gap between a tungsten electrode ( 11 ) and an insert chip ( 12 ) at a flow rate of 2.1 m/sec or less, and supplying a shield gas ( 24 ) into the gap between the insert chip ( 12 ) and a shield cap ( 15 ), wherein a mixed gas prepared by adding either 0.5 to 4 vol % of oxygen gas or 1 to 6 vol % of carbon dioxide gas to an inert gas is used as the shield gas ( 24 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A plasma welding method comprising: providing a ferritic stainless having a plate thickness of 3 mm or less, wherein the ferritic stainless does not contain Ni; providing a plasma welding torch having a tungsten electrode, an insert chip disposed so as to surround an outer periphery of the tungsten electrode, and a shield cap disposed so as to surround an outer periphery of the insert chip, wherein a tip of the tungsten electrode is disposed inside t…
