Description
Technical field
The utility model relates to submerged-arc welding, particularly a kind of submerged-arc welding for cross column leading role weld seam.
Background technology
In the welding of steel construction product, be not also specifically designed to the submerged arc welding machine of welding cross column leading role weld seam at present, now need transform existing semi-automatic submerged arc welding machine, thus reach by the method for submerged arc welding the welding of cross column leading role weld seam.
Utility model content
Technical problem to be solved in the utility model, proposes a kind of submerged-arc welding for cross column leading role weld seam exactly.
For solving the problems of the technologies described above, technology of the present utility model by the following technical solutions:
A kind of submerged-arc welding for cross column leading role weld seam, comprise submerged-arc welding control cabinet, submerged arc welding carriage, trolley platform, vehicle guide, workpiece jig, wire reel, submerged arc welding wire-feeding mechanism and submerged-arc welding conducting rod, described vehicle guide is located on described trolley platform, described submerged-arc welding control cabinet controls submerged arc welding carriage and walks on described vehicle guide, described submerged arc welding wire-feeding mechanism by the welding wire of wire reel through submerged-arc welding conducting rod, deliver to the cross column angle welding position on workpiece jig, the length of described submerged-arc welding conducting rod can change according to the specification difference of cross column.
As preferably, can be interconnected between described submerged-arc welding conducting rod and change himself length.
Fundamentals of Welding of the present utility model are as follows:
The electric arc burnt between weldment is embedded in below graininess solder flux, arc heat makes part evaporate by welding wire end and with the direct acting mother metal of electric arc and solder melts, the gas that metal and solder flux evaporate forms an enclosed cavity around electric arc, and electric arc burns in this cavity; Cavity by one deck by slag the slag film that forms surround, this layer of slag film has not only well completely cut off contacting of air and arc and pool, and arc light can not be radiated, the welding wire being heated by the electric arc simultaneously fusing falls with the form of molten drop, is mixed to form molten bath with melting base metals.
The slag that density is less floats on molten bath, slag except to except the mechanical protection effect of molten pool metal, in welding process also with molten pool metal generation metallurgical reaction, thus affect the chemical composition of weld metal.Electric arc moves forward, and molten pool metal cools post crystallization gradually and forms weld seam.After floating over the slag cooling on molten bath, form skull and can continue to shield to the weld seam under high temperature, avoid oxidized.
When welding, submerged arc welding carriage is coordinated by motor and control cabinet, driven by motor submerged arc welding carriage is walked, simultaneously by wire feeder by the welding wire of wire reel through conducting rod, deliver to cross column angle welding position, now according to the specification of cross column, choose suitable conducting rod, because conducting rod length is variable, so become convenient when welding the angle welding of cross column, and welding job platform, and vehicle guide can change, only need regulate the length of conducting rod, semi-automatic arc welder can be utilized to carry out welding to cross column leading role weld seam.
Compared with prior art, the beneficial effect that the utility model has is: by designing and producing submerged-arc welding conducting rod, make it can adapt to the cross column requirement of different size, so just can weld the cross column of different size with semiautomatic submerged arc welding, weld by semiautomatic submerged arc welding the advantage that cross column leading role weld seam has several respects:
1, working condition is good, except alleviating manual labour intensity, under electric arc arc light is embedded in welding flux layer, does not have arc light radiation.
2, welding quality is good, because there is the protection of slag and solder flux in molten bath, make the nitrogen in air, oxygen be difficult to invade, improve intensity and the toughness of weld metal, welding quality is good.In addition, face of weld is bright and clean, smooth, shaping is beautiful, internal soundness that is weld seam can reach designing requirement.
3 welding productivities are high, utilize semiautomatic submerged arc welding can adopt larger welding current, simultaneously because electric arc heated is concentrated, fusion penetration increased.Submerged-arc welding weldering speed is compared manual welding and is improved greatly.
4, welding cost is lower, because fusion penetration is comparatively large, can not open or few bevel, decrease the loading of welding wire in weld seam, also save the used up mother metal because of finished edge during Lincoln weld.
5, by the transformation to semi-automatic submerged arc welding machine, welding cross column is made to become simple, fast, easy to operate.
