Abstract
The present invention provides an on-line coating impacted automatic welding method. The present invention comprises the steps that welding wires are cleaned to remove iron rust and oily soil; the welding wires pass through a machine head by means of mechanical transmission, and the machine head is provided with a welding flux pressure coating device; thus, welding flux is coated on the welding wires by a pressing method to continuously form the welding wires coated with the welding flux; a metal piece to be welded is directly welded by using electric arcs through the continuous formation of the welding wires. The present invention has the advantages of wide range of welding material; welding thickness can be from two millimeters to twenty millimeters; devices, such as gas protection steel bottles, etc. are not needed; during welding, a molten pool is visible, and welding processes can be monitored at any time.
Description
The present invention relates to a kind of welding method, particularly relate to a kind of electric arc welding method that is used for straight weld and plane curve weld seam.
Current in machine-building and construction, widely used arc welding method has multiple, as manual electric arc welding, automatic submerged arc welding, CO
2Gas shielded arc welding, argon arc welding etc., these welding manners respectively have its advantage and should make scope.The manual arc soldering equipment is simple, and is applied widely, but the starting the arc, to receive arc frequent, influences weldquality, and high material consumption, and productivity ratio is low.Automatic submerged arc welding productivity ratio height, welding quality is good, but usually can only downhand welding, and invisible because of electric arc, is difficult to monitor welding process.CO
2The gas shielded arc welding use cost is low, and the welding internal soundness is good, but it is big to splash, and appearance of weld is coarse, and can only welding low-carbon steel and low-alloy steel.The argon arc welding welding quality is good, but the cost height, and be difficult to adjust by welding butt welded seam alloying component.
The object of the present invention is to provide a kind of welding material applied widely, can go up welding at an arbitrary position, and be convenient to monitor the online coating impacted automatic welding method of welding process.
The online coating impacted automatic welding method of the present invention is realized by following mode, at first welding wire is cleared up, remove iron rust and greasy dirt, generation of defects such as pore, hydrogen embrittlement when preventing to weld, make welding wire pass through the head of tape welding agent pressure dressing device by machine driving again, solder flux is pressed and is coated on the welding wire, after the formation cladding has the welding wire of solder flux continuously, directly directly carries out arc welding continuously with this kind welding wire on metalwork to be welded at once.If it is stretching that welding wire when being the plate-like welding wire, need carry out welding wire earlier, make welding wire pass through the head of tape welding agent pressure dressing device by machine driving again.Welding wire is that diameter is the alloying metal silk commonly used of 0.8～6.0mm, as alloy-steel wire, alloy copper wire, alloy aluminium wire etc.Solder flux can as acid flux, alkaline solder flux, low hydrogen type flux, cellulose solder flux etc., should meet the basic demand of solder flux with existing various solder flux, as essential arc stability burning, enough low sulphur, the phosphorus content of guaranteeing; Sensitiveness to iron rust, greasy dirt and other impurity is little, to guarantee that weld seam does not produce defectives such as crack and pore; Solder flux has suitable freezing point after becoming slag, and suitable viscosity is to guarantee the appearance of weld and the removability of slag; Should not produce pernicious gas in the welding process.The thickness of cladding solder flux is generally 0.5～5.0mm on the welding wire, can change the thickness of cladded solder flux on the welding wire by adjusting the head size of tape welding agent pressure dressing device.The selection of the major parameter of welding process is determined same prior art as the selection of welding current, arc voltage, speed of welding, wire feed rate and welding wire melting rate etc. by materials to be welded.
The advantage of the online coating impacted automatic welding method of the present invention is 1) be suitable for various welding materials, but welding low-carbon steel, low-alloy steel, heat resisting steel and bimetal etc.2) thickness of soldered metal is generally 2～20mm.3) can carry out all-position welding, easy to operate.4) different solder flux can be matched for same welding wire, and the solder paste thickness of cladding on welding wire can be adjusted.5) do not need gas shield with devices such as steel cylinder, handling safety.Monitoring is convenient in the molten bath as seen when 6) welding.
Describe the embodiment of the invention below in detail.
