Abstract
The utility model provides a be fit for high energy beam deep melting welded end joint, including thin wall flange I (1), thin wall flange II (2) two parts are constituteed, thin wall flange I (1) and thin wall flange II (2) are fixed together, and weld in seam crossing, form a round welding seam (4), its characterized in that, thin wall flange I (1) left side increases a thin wall flange I annular boss (3), thin wall flange II right side increases a thin wall flange II annular boss (5), width m3 of thin wall flange I annular boss (3) and the width m5 of thin wall flange II annular boss (5) all are greater than welding depth h. The utility model provides a thin wall flange when melting the welding deeply because the thin flange edge that leads to of flange wall thickness problem of collapsing to make welding position wall thickness bodiness owing to increased the boss, improved the temperature gradient after the welding process is heat-conducting, and then strengthened the protection effect of welding process flange side, avoided the oxidation that welding high temperature leads to the influence of performance.
Description
Technical Field
The utility model relates to a be fit for high energy beam deep melting welded termination joint relates to a termination joint, and especially two parts are waited to connect the position and are thin wall metal flange, and the flange passes through the welded joint that termination joint form is connected.
Background
At present, flange connection is a common connection mode in various cooling devices, and the common connection mode includes welding, screwing and the like. In view of structural sealing and corrosion resistance, welding is most commonly used, and joints are usually butt jointed or terminated. When the wall thickness of the flange is less than 2mm, in order to ensure good sealing requirements and welding penetration requirements not lower than the wall thickness of the flange, a termination joint form is generally adopted, and the connection is performed by an electron beam welding method or a laser high-energy beam welding method, wherein the joint form is shown in fig. 1. Welding with this joint form is generally problematic in several respects: 1) due to the fact that the wall thickness of the flange is thin, metal on two sides of the flange is seriously oxidized due to heat conduction in the welding process, and performance is reduced; 2) the high-energy beam welding line is wide at the top and narrow at the bottom, and the flange edge collapse defect is easy to occur in the welding process due to the thin thickness of the flange wall.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a flange joint's termination welded joint has solved thin wall flange high energy beam deep fusion welding problem.
A terminal joint suitable for high-energy beam deep fusion welding comprises a thin-wall flange I1 and a thin-wall flange II 2, wherein the thin-wall flange I1 and the thin-wall flange II 2 are fixed together and welded at a joint to form a circle of welding seam 4, and the terminal joint is characterized in that an annular boss 3 of the thin-wall flange I is additionally arranged on the left side of the thin-wall flange I1, an annular boss 5 of the thin-wall flange II is additionally arranged on the right side of the thin-wall flange II, and the width m3 of the annular boss 3 of the thin-wall flange I and the width m5 of the annular boss 5 of the thin-wall flange II are both.
The thickness n3 of the annular boss 3 of the thin-wall flange I is larger than the thickness f1 of the wall of the thin-wall flange I, and the thickness n5 of the annular boss 5 of the thin-wall flange II is larger than the thickness f2 of the wall of the thin-wall flange II.
The utility model provides a thin wall flange when melting the welding deeply because the thin flange edge that leads to of flange wall thickness problem of collapsing to make welding position wall thickness bodiness owing to increased the boss, improved the temperature gradient after the welding process is heat-conducting, and then strengthened the protection effect of welding process flange side, avoided the oxidation that welding high temperature leads to the influence of performance.
