Abstract
The invention discloses a thickness plate welding process. The thickness of the thick plate is 10 mm. The thick plate welding process includes the first step of preparing before welding, the second step of tack welding, the third step of welding and the fourth step of processing after welding. The thick plate welding process has the beneficial effects that the welding steps are simplified; the welding mode is simple; material selection is accurate and standard; the welding quality of a thick plate can be ensured; the standard welding mode is provided for the thick plate being 10 mm in thickness; fast and safe welding of the thick plate being 10 mm in thickness is facilitated.
Description
Technical field
The present invention relates to welding technique field, is more particularly a kind of slab welding process.
Background technology
Different welding methods has different welding procedures.Welding procedure is mainly according to material, the trade mark, the chemical composition of welded piece, and weldment structure type, welding performance requires to determine.First will determine welding method, as manual metal-arc welding, submerged-arc welding, argon tungsten-arc welding, gas metal-arc welding etc., the kind of welding method is very many, can only select as the case may be.After determining welding method, reenact welding condition, the kind of welding condition is different, as manual metal-arc welding mainly comprises: welding rod model (or trade mark), diameter, electric current, voltage, source of welding current kind, polarity connection, the welding number of plies, number of channels, the method for inspection etc.But, due to the diversity of welding manner and welding material, there is various abnormal activity in welding process, and then cause the quality of welding work pieces lower, sometimes also there will be accident.
Summary of the invention
Technical scheme of the present invention is achieved in that a kind of slab welding process, and the thickness of slab is 10mm, comprises the following steps:
(1) prepare before welding
The first, check that whether surface of the work is moist, if welded again after the dryings such as the moist need of surface of the work;
The second, clean the greasy dirt of welding position, aluminium bits, oxide-film, expose metallic luster;
Three, the selection of welding manner and welding material, selects Ar gas shielded arc welding to weld, the welding wire of H08Mn2SiA grade of steel; Wherein the purity of Ar is 99.999%;
Four, pasting protective film on slab, must not have bubble in diaphragm;
(2) tack weld
The first, according to the size of welding structural element, the length of spot welding selects 10 ~ 120mm;
The second, spot welding Noticed Problems, the size of weld seam after the height of tack weld and width must not exceed, a part for weld seam after should being, arc crater should fill up, for important Welding Structure under possible condition, should spot welding overleaf, after the spot welding at the back side should being sliced off after front welds, weld the back side again, spot welded joint has must to slice off during crackle to be rewelded;
(3) weld
Docking I shape groove, selects the welding wire of 3.0mm diameter, the welding current of 130-150A, the weldingvoltage of 19-22V, welds with the speed of welding that 10-18L gas flow per minute, 350-500mm are per minute;
(4) after welding treatment
The first, unsightly weld seam is polished, and clear up splash;
The second, the welding deformation of quality and outward appearance is affected with flame or mechanical checkout.
Beneficial effect of the present invention: this invention simplifies welding step, welding manner is simple, and material selection exact specification, can ensure the welding quality of slab, be the welding manner that the slab of 10 millimeters thick provides a kind of specification, be conducive to the slab welding fast and safely of 10 millimeters thick.
Detailed description of the invention
Embodiment provided by the invention is described in further detail:
A kind of slab welding process, the thickness of slab is 10mm, comprises the following steps:
(1) prepare before welding
The first, check that whether surface of the work is moist, if welded again after the dryings such as the moist need of surface of the work;
The second, clean the greasy dirt of welding position, aluminium bits, oxide-film, expose metallic luster;
Three, the selection of welding manner and welding material, selects Ar gas shielded arc welding to weld, the welding wire of H08Mn2SiA grade of steel; Wherein the purity of Ar is 99.999%;
Four, pasting protective film on slab, must not have bubble in diaphragm;
(2) tack weld
The first, according to the size of welding structural element, the length of spot welding selects 10 ~ 120mm;
The second, spot welding Noticed Problems, the size of weld seam after the height of tack weld and width must not exceed, a part for weld seam after should being, arc crater should fill up, for important Welding Structure under possible condition, should spot welding overleaf, after the spot welding at the back side should being sliced off after front welds, weld the back side again, spot welded joint has must to slice off during crackle to be rewelded;
(3) weld
Docking I shape groove, selects the welding wire of 3.0mm diameter, the welding current of 130-150A, the weldingvoltage of 19-22V, welds with the speed of welding that 10-18L gas flow per minute, 350-500mm are per minute;
(4) after welding treatment
The first, unsightly weld seam is polished, and clear up splash;
The second, the welding deformation of quality and outward appearance is affected with flame or mechanical checkout.
Beneficial effect of the present invention: this invention simplifies welding step, welding manner is simple, and material selection exact specification, can ensure the welding quality of slab, be the welding manner that the slab of 10 millimeters thick provides a kind of specification, be conducive to the slab welding fast and safely of 10 millimeters thick.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
