Abstract
The invention discloses an electric arc welding process for a 16Mn steel plate and relates to the technical field of welding processes. The electric arc welding process mainly involves the four steps of preparation before welding, tack weld, welding and post-weld treatment. According to the electric arc welding process for the 16Mn steel plate, the welding steps are simplified, the welding mode is simple, material selection is accurate and standard, the welding quality of the 16Mn steel plate can be guaranteed, a standard welding mode is provided for the 16Mn steel plate, and fast and secure welding of the 16Mn steel plate is facilitated.
Description
Technical field
The present invention relates to welding technique field, is more particularly a kind of electric arc welding technique of 16Mn 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 to make up the deficiencies in the prior art, a kind of electric arc welding technique of 16Mn steel plate is provided.
The object of the invention is to be achieved through the following technical solutions:
An electric arc welding technique for 16Mn steel plate, the thickness of steel plate is 4mm, it is characterized in that: comprise the following steps:
(1) process of weldment and the selection of welding material
The first, remove weldment surface contaminants, as become block iron rust oxide, greasy dirt etc., surface have ponding or accumulated snow need first remove ponding or accumulated snow;
The second, adopt electric arc welding, select the welding rod of E5016 model, the J506 trade mark, the diameter of welding rod selects 3.2mm;
Three, dry the welding rod that makes moist, prevent pore and cold crack, basic electrode must be dried;
(2) tack weld
The first, adopt manual electric arc welding to carry out tack weld, the electric current of tack weld is 90-130A, and spot welding length selects 10-80mm according to workpiece size;
The second, tack weld points for attention, the size of weld seam after the height of tack weld and width must not exceed, a part for weld seam after should being, spot welding and the welding rod formally welded with the same trade mark, arc crater should fill up, for important welding structural element under possible condition, should spot welding overleaf, when the spot welding at the back side should be sliced off after front welds according to after weld the back side again, spot welded joint has must to slice off during crackle to be rewelded, must not in workpiece welding with outer surface striking;
(3) weld
Adopt manual electric arc welding to weld, core diameter is 3.2mm, and welding current is 90-130mm, for longer weld seam, and especially full weld welding from the middle to both ends, sectional is interrupted welding to reduce welding deformation;
(4) after welding treatment
The first, welding slag and splash is removed;
The second, inaesthetic weld seam is polished;
Three, the welding deformation of quality and outward appearance is affected with flame or mechanical checkout.
The invention has the advantages that:
The electric arc welding technique of a kind of 16Mn steel plate provided by the invention, simplify welding step, welding manner is simple, material selection exact specification, the welding quality of 16Mn steel plate can be ensured, for 16Mn steel plate provides a kind of welding manner of specification, be conducive to the welding fast and safely of 16Mn steel plate.
