Abstract
The invention relates to a weld repair technology and particularly relates to a method for carrying out weld repair on cast aluminium alloy cylinder covers of automobile engines. According to the invention, the problem that when the surfaces of cast aluminium alloy cylinder covers of the existing automobile engines have air holes, the weld repair only can be performed on shallow holes, and the weld repair effect is not good. The method provided by the invention comprises the following steps: cleaning a surface to be subjected to weld repair and a special aluminum alloy welding rod by using acetone and alcohol, and carrying out weld repair on air holes through argon shielded welding; when half depth of air holes are subjected to weld repair, striking the weld repair surface by using a hammer with an arc surface, so that welding fluxes are filled with air holes; and carrying out weld repair on the weld repair surface again, when the surface to be subjected to weld repair is 2 mm higher than the that of a workpiece, striking the weld repair surface by using the hammer with an arc surface, so that the weld repair surface is even with the surface of the workpiece. The method provided by the invention is simple in operation, and can be widely applied to the cast aluminium alloy cylinder covers of all automobile engines.
Description
Technical field
The present invention relates to a kind of soldering technology, be specially a kind of repair method of automobile engine Birmasil cylinder cover.
Background technology
At present, automobile engine Birmasil cylinder cover when casting surface pore occurs through regular meeting, and existing processing method is to melt down or carry out soldering, and its repair welding rate is more than 15%.Soldering is the mode that adopts the argon shield weldering, but this soldering mode can only be carried out soldering less than D10, the degree of depth less than the shallow bore hole of 2mm to the aperture; And the effect of soldering is bad, and interior tissue is easy to generate the pin hole that internal diameter is little and density is bigger, and success rate can only reach about 70%.
Summary of the invention
The present invention can only provide a kind of repair method of automobile engine Birmasil cylinder cover in order to solve at shallow bore hole and the bad problem of welding effect when existing automobile engine Birmasil cylinder head surface pore occurs and carries out soldering.
The present invention adopts following technical scheme to realize: a kind of repair method of automobile engine Birmasil cylinder cover comprises the steps:
(1) it is clean with acetone or alcohol wash to carry out lip-deep greasy dirt, booty and the special-purpose aluminium alloy electrode of soldering, with the argon shield weldering pore is carried out soldering;
(2) in soldering when half degree of depth of pore, with the hammer of being with cambered surface soldering surface (the soldering surface is meant the solder surface that is positioned at pore) beaten and to make scolder be full of pore, reach the uniform purpose of interior tissue;
(3) carry out soldering again, treating when the soldering surface exceeds surface of the work 2mm that hammer with the band cambered surface beats the soldering surface makes the soldering surface equal with surface of the work, thereby reaches interior tissue evenly and eliminate the purpose of the less and pin hole that density is bigger of interior tissue generation.
The dynamics of beaing of described hammer is 16.1-26.8Kg; The number of times that beats of described hammer is 15-25 time.The weight of described hammer is 1.5-2.5Kg.
The present invention is simple to operate, and pore that produces in the time of can casting automobile engine Birmasil cylinder cover or the fabrication hole of reserving for the solution technological problems carry out effective shutoff, the inner pin hole that produces when preventing soldering simultaneously; Not only can carry out soldering less than D10, the degree of depth less than the shallow bore hole of 2mm to the aperture, and also can carry out soldering greater than D10, the degree of depth greater than the deep hole of 2mm for the aperture, success rate can reach 100%, has improved the effective rate of utilization of product; Solved when existing automobile engine Birmasil cylinder head surface pore occurs and carries out soldering and can only can be widely used in all automobile engine Birmasil cylinder covers at shallow bore hole and the bad problem of welding effect.
