Abstract
The title of the invention is: anti-deformation welding technology for a steel member, relating to a welding technology. The invention discloses an anti-deformation technology for a steel member. The technology uses a set of simple special technology equipment. When welding, the deformation tendency of two steel member, which are opposite against one the other, become two external forces that balance out deformation force, which curbs the occurrence of deformation after welding.
Description
[technical field]
The present invention relates to a kind of steel member welding procedure, especially a kind of anti-deformation welding procedure.
[background technology]
In the welding of steel member, because the cooled contraction of weld seam can cause the steel member welding deformation to occur.I-shaped weldment with commonly used is an example, and the perfect condition of the flange plate up and down of weldment should be straight, like Fig. 1.But the phenomenon that in fact flange plate can occur staying after the welding is like Fig. 2.Present method is normally used the special mechanical equipment leveling, or with the leveling of firer's method.The former invests greatly, and latter's efficient is low, and power consumption is high.
[summary of the invention]
The purpose of this invention is to provide a kind of steel member anti-deformation welding procedure, this technology is simple, practicality, and cost is low.
For realizing above-mentioned purpose, steel member anti-deformation welding procedure of the present invention need be purchased the harness of number cover special tool, and they are U type folder 2, chock 3.
Before the welding; The steel member flange plate that earlier welds two points aligns each other and is close to, and the length direction cover that whenever keeps at a certain distance away is put a U type folder 2 along the edge of a wing, and with two chocks 3 in the opposite direction press from both sides the U type 2 urgent; Make U type folder 2 overlap the flange plate that blocks two members firmly, see Fig. 3, Fig. 4.
During welding, Fig. 3 was fallen, about simultaneously the welding.When weld seam cooled off, the right and left shrank simultaneously, and the power on both sides is balances; Convergent force separately has been applied on the other side's the flange plate through U type folder 2; And the direction of this power in the opposite direction with the other side's convergent force just in time, thereby played the effect of conditioning each other, avoided welding deformation.
After treating the weld seam cooling, make loose chock 3, take down U type folder 2 and get final product with hammer.
The characteristics of this technology are to block two workpiece with a cover special mould clamp, utilize two characteristics that workpiece deformation trend is opposite, and the other side that conditions each other finally reaches the effect that both sides can't deform.
[description of drawings]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.Wherein:
Fig. 1 is a steel member welding back perfect condition sketch map.
Fig. 2 is a common steel member welding back view.
Fig. 3 is that sketch map is used in steel member anti-deformation welding procedure special tool harness of the present invention.
Fig. 4 is that sketch map is used in steel member anti-deformation welding procedure special tool harness of the present invention.
Fig. 5 is that steel member anti-deformation welding procedure special tool harness U type of the present invention presss from both sides 2 sketch mapes.
Fig. 6 is steel member anti-deformation welding procedure special tool harness chock 3 sketch mapes of the present invention.
Wherein Reference numeral representes that respectively 1-treats the welding steel member, 2-U type folder, 3-chock.
[specific embodiment]
Press sketch map Fig. 3, the represented that kind of Fig. 4, fix steel member 1, Fig. 3 was fallen with U type folder 2 and chock 3, about welding simultaneously, stand up the weldering another side after welding one side, treat the weld seam cooling after, make loose chock 3 with hammer, take down U type folder 2 and get final product.
