Abstract

The invention discloses a welding technology for a steel plate and relates to the technical field of welding technologies. The welding technology includes four steps of preparing before welding, tack welding, welding and processing after welding. According to the welding technology for the steel plate, the welding steps are simplified, the welding mode is simple, material selection is accurate and standard, the welding quality of a steel pipe can be ensured, a standard welding mode is provided for the steel plate 1 millimeter in thickness, and the steel plate which is 1 mm in thickness can be easily, rapidly and safely welded.

Description

A kind of welding procedure of steel plate
Technical field
The present invention relates to welding technique field, is more particularly a kind of welding procedure of steel plate.
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
The object of the invention is, in order to make up the deficiencies in the prior art, to provide a kind of welding procedure of steel plate.
The object of the invention is to be achieved through the following technical solutions:
A welding procedure for steel plate, the thickness of its light plate is 1 millimeter, it is characterized in that: comprise the following steps:
(1) preparation before welding:
The first, to-be-welded pieces surface contaminants is removed, as iron filings, greasy dirt etc.;
The second, select welding manner and select welding material, select gas tungsten arc welding to weld, welding wire selects H08Mn2SiA grade of steel welding wire, and solder flux adopts AC welding set;
Three, know ponding and the accumulated snow on weldment surface, ensure the drying of weldment;
(2) tack weld:
The first, the height of tack weld and width must not exceed after the size of weld seam, a part for weld seam after should being;
The second, according to the size of welding structural element, the length optional of spot welding selects 10 ~ 80mm;
Three, arc crater is filled up;
Four, important Welding Structure, should spot welding overleaf under possible condition, after the spot welding at the back side should being sliced off after front welds, then welds the back side;
(3) weld:
Adopt the electrode diameter of 1.6mm, the welding current of 50-80A, the filler wire diameter of 4mm, gas flow 4-6L is per minute, welds with the speed that 100-120mm is per minute; Two operators respectively outside workpiece and inner face synchronously carry out from bottom to top manual TIG welding vertical position welding, during welding, take as the leading factor with the welding gun outside workpiece, carry out orderly welding gun to swing and fill silk, the welding gun of inner face does not burn, back lifting gas shielded effect, to strengthen inner face protection, guarantees that weld seam inner face is well shaped;
(4) after welding treatment:
The first, inaesthetic 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.
The invention has the advantages that:
The welding procedure of a kind of steel plate provided by the invention, simplify welding step, welding manner is simple, material selection exact specification, the welding quality of steel pipe can be ensured, be the welding manner that the steel plate of 1 millimeters thick provides a kind of specification, be conducive to the steel plate welding fast and safely of 1 millimeters thick.
Detailed description of the invention

(1) preparation before welding:
The first, to-be-welded pieces surface contaminants is removed, as iron filings, greasy dirt etc.;
The second, select welding manner and select welding material, select gas tungsten arc welding to weld, welding wire selects H08Mn2SiA grade of steel welding wire, and solder flux adopts AC welding set;
Three, know ponding and the accumulated snow on weldment surface, ensure the drying of weldment;
(2) tack weld:
The first, the height of tack weld and width must not exceed after the size of weld seam, a part for weld seam after should being;
The second, according to the size of welding structural element, the length optional of spot welding selects 50mm;
Three, arc crater is filled up;
Four, important Welding Structure, should spot welding overleaf under possible condition, after the spot welding at the back side should being sliced off after front welds, then welds the back side;
(3) weld:
Adopt the electrode diameter of 1.6mm, the welding current of 60A, the filler wire diameter of 4mm, gas flow 6L is per minute, welds with the speed that 120mm is per minute; Two operators respectively outside workpiece and inner face synchronously carry out from bottom to top manual TIG welding vertical position welding, during welding, take as the leading factor with the welding gun outside workpiece, carry out orderly welding gun to swing and fill silk, the welding gun of inner face does not burn, back lifting gas shielded effect, to strengthen inner face protection, guarantees that weld seam inner face is well shaped;
(4) after welding treatment:
The first, inaesthetic 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.
