Connector used between TIG welding burner and welding machine - where two control cables are shielded from high frequency current fed to burner by tube in connector plugThe connector has a central block made of insulating material and provided with a current connector bolt entered by a current ...
employed to reduce or suppress the formation of ozone created by the ultraviolet radiation. Arc welding produces noxious gases such as O3, and NOx, but the O3 is most harmful to human health and must therefore be removed. 展开 收藏 引用 批量引用 报错 分享 ...
Welding Procedure for Dual-phase Steel Tubes and Tube sheets used in Heat Exchanger Dual-phase steel tubes are welded on tube sheets by the means of automatic TIG technique.The welded joints are subject to liquid penetrant test,radiographi... E Shang - 《Cfhi Technology》 被引量: 1发表: 20...
As the result being welded, the flux core wire which is sealed there is no vapor nitrogen substantially, desirably, vapor nitrogen, there is no vapor, or a vapor hydrogen completely can use at the time of TIG, MIG, MAG, and submerged arc welding processing.ボネ,クリスチャン...
The protective gas nozzle is pref. a separate accessory used on the burner, and partial or complete screening of the ultraviolet radiation in the arc is pref. employed to reduce or suppress the formation of ozone created by the ultraviolet radiation. Arc welding produces noxious gases such as ...
Outlet zone is fitted with a thermocouple used to control the feeder motor, and also to adjust the vol. of a coolant fed into the inlet zone of the guide tube. Used e.g. in MIG, MAG, or TIG welding; or to permit the use of Ni-Cr-Mo alloys instead of Ag- or Au- alloys in ...

Welding is pref. carried out in a protective gas, and the NO etc. is pref. mixed with the gas in its inlet pipe or in the electrode carrier; alternatively, the NO etc. can be fed to the arc without mixing with the protective gas. Another alternative is to use coated electrode wire ...
