Abstract
The invention discloses a seam welder electrode wheel for invar boards of a liquid cargo tank of an LNG (Liquefied Natural Gas) ship. The wheel is characterized by comprising a wheel body, wherein a welding working surface of the electrode wheel is arranged on an external circumference surface of the wheel body; annular oblique surfaces are arranged between the two side end surfaces of the wheel body and the welding working surface; a circular groove is formed on one side end surface of the wheel body coaxially; a circular sealing board is arranged on the other side end surface of the wheel body coaxially; a mounting hole set is axially arranged between the circular sealing board and the circular groove in a penetrating way; the wheel body is internally provided with a circulating water channel; and a water inlet hole and a water outlet hole are formed in the center of the circular groove, and are communicated by the circulating water channel. The wheel has the advantages that since the wheel is combined with a seam welder, continuous automatic welding of the invar boards of the liquid cargo tank of the LNG ship can be realized; the welding efficiency is improved greatly; the welding quality is easy to control; and the stability is better.

Technical field
The present invention relates to a kind of electrode of seam welder wheel, especially relate to the electrode of seam welder wheel for LNG ship cargo tank invar plate.
Background technology
LNG(Liquefied Natural Gas) ship is the specialized ships of transport liquefied gases under subzero 163 degrees centigrade of low temperature, is high-tech, " three height " highly difficult, high added value product, is a kind of " marine super van cooler ".At present, manual argon arc welding is adopted in the welding of invar plate more, and one 170,000 tons LNG ship cargo tank invar plate welding seams reach more than 15 myriametres, and the welding job amount is huge.Adopt manual welding, its welding efficiency is low, welding quality is wayward, and less stable can't satisfy the welding requirements of LNG ship at all.
Summary of the invention
Technical problem to be solved by this invention provides a kind of welding efficiency height, welding quality is controlled easily, and stability is used for the electrode of seam welder wheel of LNG ship cargo tank invar plate preferably.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of electrode of seam welder wheel for LNG ship cargo tank invar plate, comprise wheel body, the outer circumference surface of wheel body is provided with the welding job face of electrode wheel, be provided with annular slope between the both sides end face of wheel body and the described welding job face, the coaxial circular groove that offers on one side end face of wheel body, be coaxially arranged with the circular seal plate on the opposite side end face of wheel body, axially run through between described circular seal plate and the described circular groove and be provided with the installing hole group, be provided with circulating water chennel in the described wheel body, described circular groove center is provided with inlet opening and apopore, and described inlet opening is connected by described circulating water chennel with described apopore.
Described circulating water chennel comprises ring-shaped groove, water inlet groove and water outlet groove, one end of described water inlet groove is connected with described inlet opening, the other end of described water inlet groove is connected with described ring-shaped groove, one end of described water outlet groove is connected with described apopore, and the other end of described water outlet groove is connected with described ring-shaped groove.
Be provided with circular weld between described circular seal plate and the described wheel body, described circular seal plate welds together by silver brazing and described wheel body.
Described installing hole group comprises that 4 have a rectangular shape the installing hole that is arranged on described wheel body center.
The material of described wheel body is chrome copper, chromium 0.4 ~ 1.2wt%, and other impurity content is no more than 0.3 wt%, and all the other are copper, and it conducts electricity very well, and mechanical behavior under high temperature is good.
Compared with prior art, the invention has the advantages that by this device bonding crack welding machine and can realize the continuous of LNG ship cargo tank invar plate welded automatically that greatly improved welding efficiency, welding quality is controlled easily, and stability better.
