Abstract
The invention discloses the welding procedure of a kind of steel plate, relate to welding technique field, mainly include welding front preparation, tack weld, welding, four steps of after welding treatment.The welding procedure of a kind of steel plate that the present invention provides, simplifies welding step, and welding manner is simple, material selection exact specification, can guarantee that the welding quality of steel pipe, be the steel plate of the 1 millimeters thick welding manner that provides a kind of specification, the welding fast and safely of the steel plate of beneficially 1 millimeters thick.
Description
Technical field
The present invention relates to welding technique field, the welding procedure of a kind of steel plate.
Background technology
Different welding methods has different welding procedures.Welding procedure is mainly according to the material of welded piece, the trade mark, chemical composition, weldment structure type, and welding performance requires to determine.First having to determine welding method, such as manual metal-arc welding, submerged-arc welding, argon tungsten-arc welding, gas metal-arc welding etc., the kind of welding method is the most, 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 specifically includes that 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, method of inspection etc..But, due to welding manner and the multiformity of welding material, welding process also exists various abnormal activity, and then causes the quality welding workpiece relatively low, sometimes there is also accident.
Summary of the invention
The invention aims to make up the deficiencies in the prior art, it is provided that the welding procedure of a kind of steel plate.
It is an object of the invention to be achieved through the following technical solutions:
A kind of welding procedure of steel plate, the thickness of its light plate is 1 millimeter, it is characterised in that: comprise the following steps:
(1) preparation before welding:
The first, to-be-welded pieces surface contaminants is removed, such as iron filings, greasy dirt etc.；
The second, selecting welding manner and select welding material, selecting gas tungsten arc welding welding, welding wire selects H08Mn2SiA grade of steel welding wire, and solder flux uses AC welding set；
3rd, hydrops and the accumulated snow on weldment surface are understood, it is ensured that being dried of weldment；
(2) tack weld:
The first, the size of weld seam, a part for weld seam after should being after the height of tack weld and width must not exceed；
The second, according to the size of welding structural element, the length of spot welding may select 10～80mm；
3rd, arc crater is filled up；
4th, important Welding Structure may under conditions of, should spot welding overleaf, after the spot welding at the back side should being sliced off after front welds, then weld the back side；
(3) welding:
Using 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 synchronize the manual TIG welding vertical position welding carried out from bottom to top respectively outside workpiece with inner face; 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 burns; back lifting gas shielded effect, to strengthen inner face protection, it is ensured that weld seam inner face well shapes；
(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.
It is an advantage of the current invention that:
The welding procedure of a kind of steel plate that the present invention provides, simplifies welding step, and welding manner is simple, material selection exact specification, can guarantee that the welding quality of steel pipe, be the steel plate of the 1 millimeters thick welding manner that provides a kind of specification, the welding fast and safely of the steel plate of beneficially 1 millimeters thick.
