Description
Invention field
The present invention relates to a kind of welding procedure of steel, be specifically related to a kind of mixed gas protected consumable-electrode weld welding procedure of 6mm steel plate material.
Background technology
Gas metal-arc welding utilizes the electric arc produced between welding wire and workpiece to make thermal source by the welding method of metal molten.In welding process, the molten bath that arc-melting welding wire and mother metal are formed and welding region, under the protection of inert gas or active gases, can stop the illeffects of ambient air effectively.What adopt is that electric arc between fusible welding wire and weldment comes filler wire and base metals as thermal source, and to weld zone conveying protective gas, makes electric arc, the welding wire of fusing, molten bath and neighbouring base metals from the illeffects of surrounding air.
Summary of the invention
For solving the problem, the invention provides a kind of mixed gas protected consumable-electrode weld welding procedure of 6mm steel plate material.
The technical solution used in the present invention is:
A mixed gas protected consumable-electrode weld welding procedure for 6mm steel plate material, is characterized in that, comprise the following steps:
(1) by after the welding position cleaning of steel plate to be welded material, in the middle of welding position, double V-groove is opened;
(2) mother metal of 100 ~ 150mm scope around weld seam is slowly preheating to 500 ~ 600 DEG C;
(3) regulate welding condition, adopt mixed gas protected consumable-electrode weld, protective gas is CO
2and Ar, gas flow is 15 ~ 18L/min; Adopt pulse current to weld during welding, welding current is 220 ~ 240A, and voltage is 23 ~ 27V, speed of welding 380 ~ 420mm/min, shredded dried bean curd elongation 15mm;
(4) first tack weld is carried out overleaf during welding, the size of weld seam after the height of tack weld and width must not exceed, the length optional of spot welding selects 10 ~ 80mm, after the spot welding at the back side should being sliced off after front welds, weld the back side again, should welding as far as possible from the middle to both ends for longer weld seam especially full weld, to reduce welding deformation.
Further, the ratio of protective gas when described steel is carbon steel is the Ar of the 80% and CO of 20%
2; The ratio of protective gas when described steel is stainless steel is the Ar of the 97.5% and CO of 2.5%
2.
Further, according to the corresponding flux-cored wire of the Material selec-tion of steel during welding, flux-cored wire adopts pure CO
2gas shield.
Beneficial effect of the present invention:
The invention process is convenient, and welding efficiency is high, and mixed gas arc welding is conventional welding method, and equipment and consumptive material are easy to buying and realize, and welder is easy to grasp and implements, and can adopt automatic welding process, welding efficiency is high, and weld defect incidence is low.
