Specific embodiment
For make present invention solves the technical problem that, the technical scheme that uses and the technique effect that reaches it is clearer, below
Technical scheme is further illustrated with reference to accompanying drawing and by specific embodiment.
The present invention provides a kind of vertical corner connection double-wire automatic welding and connects method, and being mainly used in shipbuilding industry (can be used for
Other steel construction industries) in thickness range be 10-20mm, fit-up gap for 0-5mm vertical corner joint welding, during welding,
Using two welding guns arranged up and down while being welded to one fillet weld in the vertical position, wherein a welding gun is responsible for bottoming above, protect
Card weld seam basic point fusion, below a welding gun be responsible for swinging capping, it is ensured that weld size and good shaping, so as to realize leg chi
The efficient automatic welding of Ship Structure fillet weld in the vertical position of very little 10-14mm, effectively reduces shipbuilding neutrality fillet weld seam, polishing
Man-hour and labour intensity, improve fillet weld in the vertical position welding efficiency and quality.
Referring to Fig. 1 and Fig. 2, in the present embodiment, the vertical corner connection double-wire automatic welding connects concretely comprising the following steps for method：
S1：The vertical angle automatic welding carriage of debugging mariages, according to welding point concrete condition, completes the works such as trolley track positioning
Make, connect dolly power supply, welding tractor adjusts trolley track, it is ensured that weldering in time along the vertical walking upwards of track according to welding wire position
Silk alignment angle Weld pipe mill, welding gun stem elongation 15-20mm all the time；
S2：Two angles of welding gun of adjustment, top welding gun is bottoming welding gun 1, and bottoming welding gun 1 is 3- with the angle of horizontal plane
5 degree, lower section welding gun is capping welding gun 2, and capping welding gun 2 keeps level, while ensureing welding wire 3 and capping welding gun on bottoming welding gun
On the alignment angle Weld pipe mill all the time of welding wire 4, the spacing between the welding wire 4 on welding wire 3 and capping welding gun on bottoming welding gun sets
It is set to 200-250mm；
S3：Two parameters of welding gun are set, and design parameter value is shown in Table one, and bottoming welding gun 1 is welded simultaneously with capping welding gun 2,
During welding, bottoming welding gun 1 does not swing, and capping welding gun 2 swings by axle of capping welding torch clamping mechanism in the horizontal plane, it is ensured that
Rounding off of the weld seam to mother metal.
The parameters of welding gun of table one
Motlten metal can be sunk by Action of Gravity Field during fillet welding in the vertical position so that the situation of concave and downward convex occurs in weld seam, influence weld seam
It is attractive in appearance.Especially backing run, welding gun is not swung during welding, and appearance of weld is easily caused using common flux-cored wire
It is bad, it is that the automatic fillet welding in the vertical position of this mariages is needed with the fillet welding in the vertical position flux-cored wire special (trade mark：DW110EV, specification Φ 1.2mm), protect
Card weld seam well shapes.
