Non-consumable nozzle for electro-slag welding

摘要

(57) Abstract Objective Extremely at the time of becoming erect loss lag welding of the thick steel, equalBe able to guarantee the satisfactory penetration at one, adjustment of the nozzle being easy,The non-consumable nozzle which can prevent the curvature of the nozzle is offered. Constitution The wire where the electrode tip for electrification fits to the TipThe no where distribution facilities are done the Interpolation through-hole for sending and the plumbing water flow hole for the chilled waterzuru 2 administering pre-insulation to the said nozzle rim, integral constructionIt does. Advantages Adjustment of the nozzle to simplify, the curvature of the nozzle antiBy the fact that it stops, compaction of the time when it requires for adjustment the aim of stabilizingBe able to obtain position, with improvement of endurance of the welding efficient nozzle the polar thick steelBecoming erect loss lag welding became possible.
