Abstract
The invention discloses a 16 Mn H-shaped steel welding process, and relates to the technical field of welding processes. The 16 Mn H-shaped steel welding process mainly includes the steps of preparation before welding, tack weld, welding and treatment after welding. By means of the 16 Mn H-shaped steel welding process, the welding steps are simplified, a welding mode is simple, material selection is precise and standard, the welding quality of steel plates can be guaranteed, the standard welding mode is provided for the 16 Mn H-shaped steel plates, and quick and safe welding of the 16 Mn H-shaped steel plates is facilitated.
Description
Technical field
The present invention relates to welding technique field, is more particularly a kind of welding procedure of 16Mn I-steel.
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 to make up the deficiencies in the prior art, a kind of welding procedure of 16Mn I-steel is provided.
The object of the invention is to be achieved through the following technical solutions:
A welding procedure for 16Mn I-steel, wherein the wing plate thickness of I-steel to be welded is 8mm, and web thickness is 6mm, it is characterized in that, comprises the following steps:
(1) welds prepares:
The first, weldment surface contaminants is removed, as become block iron rust oxide, greasy dirt etc.;
The second, welding wire surface is cleaned, inaccurate corrosion;
Three, the solder flux that will make moist is dried;
(2) tack weld:
The first, tack weld is carried out with manual electric arc welding; When assembly structure gap is greater than 1mm, should first manual backing welding.
The second, the height of tack weld and width must not exceed after the size of weld seam, a part for weld seam after should being.
Three, the length of spot welding selects 50 ~ 80mm.
Four, arc crater is filled up.
(3) weld
The first, select DC reverse connection electric welding machine, diameter is the weldingvoltage of the welding current of the welding wire of 4mm, 400-425A, 24-27V, soldering angle 5mm, then carries out Lincoln weld with the speed that 400-500mm is per minute.
(4) after welding treatment
The first, welding slag and splash is removed.
The second, the repair welding of weld defect place is had.
Three, the welding deformation of correct influences quality and outward appearance.
The invention has the advantages that:
The welding procedure of a kind of 16Mn I-steel provided by the invention, simplify welding step, welding manner is simple, material selection exact specification, the welding quality of steel pipe can be ensured, for 16Mn I-steel provides a kind of welding manner of specification, be conducive to the welding fast and safely of 16Mn I-steel.
