A high-energy-beam fillet welding seam joint comprises a bottom plate and a vertical plate, wherein the vertical plate and the bottom plate are arranged at a certain angle; the fillet welding seam at junction of the two plates is welded by high-energy beams; the fillet welding seam is welded for two times; an included angle between the energy source incidence direction and the bottom plate is 20-25 degrees during welding for the first time; the incidence position inclines to one side of the vertical plate; the incidence direction is located on an angular bisector between the two plates during welding for the second time; the incidence position is located at an intersection line between the vertical plate and the bottom plate; welding wires are added during welding.
Description
Technical field
The present invention relates to the angle welding preparation method in a kind of welding point, particularly high energy beam fillet welding joint welding method, this joint is applicable to the welding such as electron beam, laser high energy beam welding, and wall thickness is more than the fillet welding joint of 3mm.
Background technology
Heat input is low, welding deformation is little owing to having for this two classes welding method of electron beam, laser, is widely used in recent years at aerospace field, and banjo fixing butt jointing, docking lock end joint, lap joint are the majority of splice forms of high energy beam welding.But in corner joint, if laser directly welds from melting welding, because laser welded seam is narrow, the effective load area formed in angle welding is little, and owing to not having packing material, cannot form arc transition outside angle welding, easily cause stress to concentrate, joint bearing capacity is low.
Summary of the invention
The object of the present invention is to provide a kind of welding method of high energy beam fillet welding joint, greatly can improve the load area of conventional angular weld seam, improve the bearing capacity of high energy beam angle welding.
A kind of high energy beam fillet welding joint, comprises base plate and riser two parts composition, and at an angle, the angle welding in two plate intersections adopts high energy beam welding for riser and base plate.Angle welding has been welded at twice, and during first time welding, energy source incident direction and base plate angle are 20 ° ~ 25 °, incoming position deflection riser side; Second time incident direction is on two plate angular bisectors, and incoming position, on riser and base plate intersection, adds welding wire during welding.
Welding method of the present invention is as follows:
The first step: riser to be welded and base plate are fixed;
Second step: welding Article 1 weld seam, during welding, energy source incident direction and base plate angle α are 20 ° ~ 25 °, and incidence point is positioned on riser, apart from riser and base plate intersection place apart from the focus diameter of to be L, L be energy source.This weld seam, to obtain for the purpose of larger fusion penetration, easily selects high-energy high speed of welding, and recommend speed of welding at more than 2.4m/min, welding penetration is not less than 1+L/sin α.
3rd step: welding Article 2 weld seam, during welding, energy source incident direction is on the angular bisector of two plates, and incidence point is positioned on riser and base plate intersection, adds welding wire during welding.This weld seam is larger molten wide in order to obtain, and easily selects low-yieldly to weld at a slow speed.
The present invention is used in high energy beam fillet welding joint, solves that binding face in high energy beam angle welding is little, weld appearance transition is unsmooth, the problem of bearing capacity difference.
