The welding method includes firstly, overlaying the checkered plate and the steel grating plate, determining positioning spots at centers of the checkered plate and the steel grating plate, and realizing spot welding; secondly, carrying out welding forming in a mode that welding spots are longitudinally scattered from the middle to two ends of the checkered plate and are spaced mutually by three flat steel pieces and one transverse rod; and thirdly, welding peripheries of the checkered plate and the steel grating plate, and galvanizing a grid composite plate after welding is completed. By the aid of the welding method, on the premise of guaranteeing the strength of the integral grid composite plate, the welding spots and welding frequencies are reduced to the greatest extent, practicality and attractiveness of an integral structure are guaranteed, the quality of the appearance of a product can be effectively improved, the service life of the product can be effectively prolonged, and accordingly problems of poor quality of appearances of products and low production efficiency due to traditional process are solved.
Description
Technical field
The present invention relates to a kind of grid composite plate manufacture field, especially a kind of welding method of grid composite plate.
Background technology
The grid composite plate is that band steel carries out cross arrangement according to certain spacing and cross bar, and has a kind of steel product of square grid in the middle of being welded into, and mainly is used for doing the ditch cover plate, steel structure platform plate, the step plate of steel ladder etc.The grid composite plate generally adopts carbon steel to make, and the appearance galvanizing can be played the effect of anti-oxidation; Also can adopt stainless steel to make, it has ventilation, daylighting; Heat radiation, anti-skidding, performance such as explosion-proof; And advantages such as high with structural strength, component quality is light, economize steel, easy for installation are in the extensive use of halfpace structure.
The manufacturing of grid and dress are welded with strict specification requirement and required precision: in manufacture process, reduce the various residual stress that assembling and welding cause as far as possible.The weld seam of all connected nodes should have good quality, and surface finish is smooth, reduces stress and concentrates, and improves anti-fatigue performance.
At present, take galvanizing by dipping after diamond plate and steel grating dispersion the carrying out acid treatment for the production of grid composite plate more in industry field, and soldering is integrated with common electric welding or gas shielded arc welding in the back that disposes.The drawback of this kind welding production method is: one, and repetitive operation causes production efficiency low.Two, after the integration welding, the high temperature that produces during owing to welding causes the position galvanizing layer scaling loss oxidation of weld seam, has a strong impact on the presentation quality and the normal service life of product.Simultaneously, in welding process, the selection of solder joint order has very big influence to product quality.
Summary of the invention
The technical problem that the present invention will solve provides a kind of production efficiency and the lifting product overall appearance quality and grid composite board welding method in service life that can improve the grid composite plate effectively.
For solving the problems of the technologies described above; The technical scheme that the present invention taked is: a kind of welding method of grid composite plate; It is characterized in that: the diamond plate and the steel grating that will plate pre-treatment are integrated welding with gas shielded arc welding; At first confirm that with the stack of diamond plate and steel grating and in the center anchor point carries out spot welding; Vertically carry out welding fabrication to two ends with the mode of distribution method, three band steels in horizontal every interval and a cross bar spacing then, carry out the weldering of diamond plate and steel grating border at last by the centre; Welding is carried out zinc-plated processing to the grid composite plate after accomplishing.Welding method among the present invention, under the situation that has guaranteed whole grid composite plate intensity, try one's best less pad and welding times guarantee integrally-built practicality, attractive in appearance.
In integrating welding process, except that outermost main body band steel and bound edge band steel can weld with diamond plate, all the other can only guarantee between the fried dough twist steel on diamond plate and the steel grating weld seam is arranged.
Said fusion length is 15 ~ 20mm, and foot welding height is 4 ~ 6mm.The restriction of butt welded seam length and foot welding height among the present invention is applicable to the welding requirements that the grid composite plate is all, and intensity can satisfy on-the-spot instructions for use; If exceed this scope; Greatly then there is no need very much, and influence aesthetic measure, then can influence product quality too for a short time.
Next door, said center is welded with the platform item.The platform item is a label that plays the sign effect, indicates operating personnel and activity duration, and in order to subsequent query, the platform item is after other solder joints welding are accomplished, in the welding.
Preferably, after said diamond plate and the steel grating stack, the border of diamond plate exceeds the steel grating border smaller or equal to 3mm.If the up and down two-layer border of grid composite plate is unjustified, and it exceeds 3mm, then for the welding of border; Be not easy to be welded in place, influence welding quality, therefore need limit this in the present invention; To satisfy quality requirement; One side owing to gapped, is not easy to fix when the grid composite plate is installed in addition.
Preferably, employed main welding equipment is CO in the said welding process
2Gas shielded welding machine.Consider on-the-spot practice of construction problem, traditional SMAW efficient is lower, also wants special molten slag removal; Adopt SMAW/submerged-arc welding method, need the SMAW bottoming, increase operation, and because the big prime coat that punctures easily of submerged-arc welding welding parameter, welding quality is difficult to guarantee, and the heat affected area is bigger, can cause certain negative effect near recombination region; CO used in the present invention
2Gas shielded arc welding is semiautomation operation, and the distortion that produces because of heat in the welding process is little, the productivity ratio of can working continuously height; Sliding along attractive in appearance after the welding without the scarfing cinder solder joint; And reduced intermediate link, and improved welding procedure efficient greatly, help guaranteeing construction speed and welding quality.
Adopt the beneficial effect that technique scheme produced to be: what the present invention taked is the one-shot forming solder technology; Welding is integrated in traditional zinc-plated back to be made into to integrate earlier after the welding zinc-plated again; The present invention can effectively solve because of repeating the temporal waste that acid treatment and immersion plating cause; And effectively improve the uniformity of product appearance color and luster, in actual production, more traditional mode of production can save for 1/3 production time; And presentation quality and the service life that can improve product effectively, thereby the appearance quality and the low problem of production efficiency that produce because of traditional handicraft have been solved always.
