The automatic welding device for circular weld that the utility model provides, beneficial effect is as follows:
1, adopt three-wheel welding tractor, front-wheel is directive wheel, trailing wheel one side be the another side of driving wheel as driven pulley, front-wheel is to advance on grooved flexible rail, frictional resistance is little, high around axe movement reliability, effectively guarantees the degree of accuracy of welding wire filling position; Adopt ripe technology of automatic submerged arc; the problem such as solved traditional SMAW and gas shielded arc welding labour intensity is large, welding efficiency is low, surface forming is poor, welding cost is high; fill up the blank on the large-scale reel structure annular of domestic water power water engineering machinery equipment automatic welding technique, broken through the application of common Lincoln weld on ring-shaped combination weld seam.This annular automatic welding technique device can be used in annular butt weld and the composite welds that diameter is greater than 1 meter, reaches domestic like product solder technology advanced level.
2, the labour intensity that significantly reduces welder, improves operating condition.No matter be original SMAW or CO 2gas shielded arc welding all belongs to manual welding; welder need to bow for a long time and bend over to operate; these two kinds of welding methods all can produce the radiation of flue dust, toxic and harmful and arc light simultaneously; these are all harmful to being engaged in the personnel of welding operation, and Lincoln weld can overcome these shortcomings completely.
3, be conducive to improve welding quality: can reduce to a great extent the dependence of welding quality to operating personnel's technical ability and quality mind, thereby can make significantly to reduce because of weld defect, hidden danger that human factor causes; Can improve the first-time qualification rate of weld seam Non-Destructive Testing, the forming of automatic welding weld appearance, can fully guarantee the stability of weldquality.
4, be conducive to reduce the direct cost that welding is produced: can significantly save electric energy, equivalent deposited metal is filled in submerged-arc welding, can save electric energy more than 25% compared with common welding rod arc welding, compared with gas shielded arc welding, save electric energy more than 15%; Under thick plate, low alloy, high strength steel welding condition, weld preheating workload is huge, causes power cost high, under automatic welding condition, owing to significantly having shortened Welder, weld power cost is significantly reduced, and welding integrated cost can reduce more than 20%; Can significantly save man-hour, reduce cost of labor; While adopting Lincoln weld to save Welder than SMAW, 40%-60%(plate is thicker, and value is larger); Compare CO 220%-40% when gas shielded arc welding is saved Welder; This means and can significantly reduce welder's demand, reduce welders training difficulty, save a large amount of labor wage;
Can save in a large number wlding: the continuous wire feed of first automatic welding, there is no the waste of discard electrode, general SMAW discard electrode abandon 10% left and right that accounts for welding rod weight; Lincoln weld deposition efficiency in addition can reach 99%, and CO 2gas shielded arc welding deposition efficiency only has 95%, and SMAW is lower, only has 55% left and right.
5, can significantly reduce the input of management cost and equipment: in the welding procedure of the circular weld of reel structure web, adopt the utility model, can greatly improve working conditions and reduce labour intensity, improve welding work efficiency, guarantee welding quality, its economic benefit and social benefit are huge, have wide popularizing application prospect.
6, the design of balancing weight has overcome the poor defect of three wheeler balance.
7, in the design Butt welding gun of pointer, whether the direction of welding wire meets welding needs and has made indication, further guarantees welding quality.
