4) Underwater Welding is carried out by 104 pairs of welded pieces 105 being submerged of welding electrode.
Needs carry out Underwater Welding with electric resistance welding equipment to the present invention to the welded piece being submerged by water in workpiece water tank
First step of method " according to the welding requirements of welded piece, gets suitable electric resistance welding equipment, workpiece water tank and welding electricity ready
The explanation in terms of specialty is made in pole ", and the technical staff of welding field both knows about, and welded piece is included by welding metal material, size, shape
Shape, structure and the difference to welding requirements, including the difference of direct welding, indirect welding, it is also of different sizes including welding electrode,
Welding electrode material is different, also differs on the electric resistance welding equipment of selection, and the structure of selected electric resistance welding equipment is different, selected
The power output of the source of welding current is different, the selected source of welding current way of output is different, and selected spot welding head is not yet
Identical, the size structure of the workpiece water tank selected by different workpiece is also not quite similar.
Electric resistance welding underwater welding technology proposed by the present invention, it is most widely used in direct welding, as long as welding electrode can be arrived at
The both sides of welded part all select direct welding, welded piece thickness to be often also required to adopt direct welding more than 0.5mm.Two-sided point
The source of welding current output current of weldering is often very big, such as welds the corrosion resistant plate of two pieces of thickness about 3.0mm and needs pulse output circuit
Up to tens kiloamperes, the heat of generation is very big, therefore direct welding electric resistance welding underwater welding equipment workpiece water tank will be therewith
It is adapted.It is well known that the heat almost half consumption that electric resistance welding is produced is in welding electrode, remaining part is in addition to nugget is formed
Still there is substantial amounts of heat to conduct to welded piece.By taking direct welding as an example, electric resistance welding Underwater Welding proposed by the present invention can make weldering
Connect heat to be highly concentrated in be formed on nugget, and the heat energy of the welded piece beyond the heat and solder joint of welding electrode occurs
Absorb rapidly in water, greatly reduce the loss of welding electrode end face, extend the service life of welding electrode, effectively subtract
The deformation of few welded piece, improves the accuracy of welding.
Finally, it should be noted that traditional carry out electric resistance welding spot welding and proposed by the present invention in water in air ambient
The electric resistance welding Underwater Welding main distinction in environment is that welding surroundings are different.As the skilled personnel to understand, electric resistance welding
The total amount of heat of generation only about 20% is used to form the welding of nugget, consumes the heat on welding electrode and accounts for 50%, consumes
Welded piece beyond nugget accounts for 30%.That is, about 80% heat is not only invalid but also harmful, radiating is not in time
Accumulation of heat can be caused to be superimposed, welding electrode will be damaged and caused welded piece deformation occur, how make the welding electricity of high temperature
Pole and welded piece quick heat radiating become the important technical barrier in electric resistance welding field.Because water is the perfect medium of heat conduction,
High temperature is radiated in atmosphere by absorptance in water and wants fast thousands of times, and present inventor has carried out electric resistance welding Underwater Welding examination
Test, have proven to its feasibility and efficiently solve technical barrier of the electric resistance welding field in radiating.
The detailed description of the specific embodiment of the invention can be seen that relative to prior art, the present invention with reference to more than
The technical barrier of radiating is welded in air ambient for electric resistance welding, it is proposed that electric resistance welding underwater welding method, electric resistance welding is existed
Air ambient welding expands to Underwater Welding, efficiently solves the technical barrier of electric resistance welding radiating, with promotion electric resistance welding industry
The meaning of scientific and technological progress.
There is no hiding it, and electric resistance welding underwater welding technology is not perfect, still there is a large amount of with regard to the concrete of electric resistance welding Underwater Welding
Technique, concrete structure, specific application process etc. need further research.
The description and announcement of book according to the above description, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula carries out appropriate change and modification.Therefore, specific embodiment disclosed and described above is the invention is not limited in, to this
Some modifications and changes of invention should also be as falling into the scope of the claims of the present invention.Although additionally, this specification
Used in some specific terms, but these terms are merely for convenience of description, do not constitute any restriction to the present invention.
