Abstract
The invention discloses a method for welding wavy welding lines, which comprises the steps: 1 cutting slots which are vertical to wavy welding lines are respectively arranged on each piece to be welded; 2 the two ends of the wavy welding lines are partially welded; and 3 the welding lines which are arranged on the two sides of the wavy welding lines are welded alternately until the two ends of the wavy welding lines, the lengths of the cutting slots are smaller than the widths of heat effect zones, and the number of the cutting slots on each piece to be welded is bigger than 4. The cutting slots adsorb welding deformation, and enables deformation amount of non-heat effect areas to be reduced to the smallest. The method for welding the wavy welding lines is obvious in effect to control deformation of the wavy welding lines, is simple and easy, and can open the cutting slots which are slightly bigger than the heat effect areas.
Description
Technical field
The present invention relates to welding technique field, is more particularly a kind of welding method of waveform weld seam.
Background technology
In existing solder technology, in process particularly to waveform weld seam (length is less than 200mm), welding deformation is very large for the impact of weldment, and conventional control welding deformation method has: point means of spot welds, be symmetrically welded, rigidly fix, heat treatment, mechanical checkout etc.
But the enforcement of these methods all has great difficulty, and the expense that will drop into is larger.
Summary of the invention
Technical scheme of the present invention is achieved in that a kind of welding method of waveform weld seam, comprises the steps:
1. slot segmentation perpendicular to waveform weld seam is set respectively in each to-be-welded pieces;
2. the two end portions of waveform weld seam is welded;
3. two side welds of staggered welding waveform weld seam are until the two ends of waveform weld seam;
Wherein, the length of described slot segmentation is less than the width in welding effect district, and in described each to-be-welded pieces, the quantity of slot segmentation is greater than 4.
Preferably, the position of described slot segmentation in described to-be-welded pieces is identical.
Preferably, downhand welding is welded as to the weld seam between slot segmentation.
Preferably, after described waveform weld seam has welded, more slot segmentations are welded.
Beneficial effect of the present invention: slot segmentation of the present invention absorbs welding deformation, makes the deflection in the non-thermal effect district of weldment be reduced to minimum; The deformation effect of this method control wave shape wave weld seam welding is obvious; This method is simple, and only the slot segmentation need driveed slightly larger than region of thermal effect just can.
Detailed description of the invention
Embodiment provided by the invention is described in further detail:
A welding method for waveform weld seam, comprises the steps:
1. slot segmentation perpendicular to waveform weld seam is set respectively in each to-be-welded pieces;
2. the two end portions of waveform weld seam is welded;
3. two side welds of staggered welding waveform weld seam are until the two ends of waveform weld seam;
Wherein, the length of described slot segmentation is less than the width in welding effect district, and in described each to-be-welded pieces, the quantity of slot segmentation is greater than 4.
Preferably, the position of described slot segmentation in described to-be-welded pieces is identical.
Preferably, downhand welding is welded as to the weld seam between slot segmentation.
Preferably, after described waveform weld seam has welded, more slot segmentations are welded.
Beneficial effect of the present invention: slot segmentation of the present invention absorbs welding deformation, makes the deflection in the non-thermal effect district of weldment be reduced to minimum; The deformation effect of this method control wave shape wave weld seam welding is obvious; This method is simple, and only the slot segmentation need driveed slightly larger than region of thermal effect just can.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
