Abstract
The invention discloses a tungsten electrode inert gas shielded arc welding process for a steel plate with the thickness of 1 mm. The tungsten electrode inert gas shielded arc welding process is characterized by comprising the following steps that a welding position of the steel plate to be welded is cleaned; a filler strip having the same component of base metal alloy is stacked on the reverse side of a weld joint, makes contact with a welded plate and then is fixed; tungsten electrode inert gas shielded arc welding is adopted, H10MnSi welding wires with the diameter of 4 mm are adopted, and the electrode diameter is 1.6 mm; during welding, single-layer single-side welding is adopted, a straight polarity direct current mode is adopted for welding machine connection, the welding current is 50 A-80 A, the welding speed is kept between 80 mm/min and 120 mm/min, and inert gas flow is 4 L/min-6 L/min; after welding is completed, the filler strip is removed, welding slag is cleaned up, the weld joint is dressed, and the steel plate is made to be attractive. The welding process is convenient to implement, welding efficiency is high, it is easy for welders to grasp and implement the welding process, the occurrence rate of weld defects is low, argon can effectively isolate ambient air, is not dissolved in metal and does not react with metal, electric arcs have the effect of automatically removing an oxidation film on the surface of a workpiece in the welding process, and welding quality is good.
Description
Invention field
The present invention relates to a kind of welding procedure of steel, be specifically related to a kind of gas tungsten arc welding welding procedure of 1mm steel plate material.
Background technology
Gas shielded arc welding utilizes adscititious gases as a kind of arc welding method of protective medium, and its advantage is that electric arc and molten bath observability are good, easy to operate; There is no slag or little slag, without the need to postwelding scarfing cinder.Inert gas is more expensive, and other arc welding method such as manual electric arc welding, submerged-arc welding, CO2 gas shielded arc welding etc. compare, and production cost is higher.Gas tungsten arc welding can be used for the welding of nearly all metal and alloy, and argon gas can completely cut off surrounding air effectively, and itself is insoluble to metal again, discord metal reaction.In argon tungsten-arc welding process, electric arc also has the effect of automatically removing surface of the work oxide-film.Due to the protection of argon gas; isolation can air to the illeffects of deposite metal; so; gas tungsten arc welding is widely used in non-ferrous metal aluminium, magnesium etc. and alloy, stainless steel, high temperature alloy, the titanium or titanium alloy of the easy oxidation of welding, also has the active metal (as molybdenum, niobium, zirconium etc.) of infusibility.
Summary of the invention
The object of this invention is to provide a kind of gas tungsten arc welding welding procedure of 1mm steel plate material.
For achieving the above object, the technical solution used in the present invention is:
A gas tungsten arc welding welding procedure for 1mm steel plate material, is characterized in that, comprise the following steps:
(1) welding position of steel plate to be welded material is carried out cleaning;
(2) identical with mother metal alloying component on weld root pad filler strip, filler strip and soldered web contact, then fix, and filler strip thickness is at 1 ~ 2mm, and width is at 10 ~ 15mm;
(3) adopt gas tungsten arc welding, welding wire employing diameter is the H10MnSi welding wire of 4mm, and electrode diameter is 1.6mm;
(4) adopt mono-layer single-face weldering during welding, welding machine connects employing straight polarity direct current mode, and welding current is 50 ~ 80A, and speed of welding remains on 80 ~ 120mm/min, and inert gas flow is 4 ~ 6L/min;
(5) after having welded, remove filler strip, cleaning welding slag, finishing weld seam, make it attractive in appearance.
Further, described inert gas is argon gas, and the purity of argon gas is 99.9%.
Further, the gas cylinder of described argon gas stands upside down 2 hours before use, discharge water 2 ~ 3 times, and air pressure remains on more than 980KPa.
Beneficial effect of the present invention:
Welding procedure of the present invention is implemented convenient, welding efficiency is high, welder is easy to grasp and implements, weld defect incidence is low, and argon gas can completely cut off surrounding air effectively, because itself is insoluble to metal again, discord metal reaction, in welding process, electric arc also has the effect of automatically removing surface of the work oxide-film, and welding quality is good.
