Abstract
The invention discloses a tungsten inert gas shielded welding process of 3mm-thickness steel plates. The welding process is characterized by including the following steps that welded surfaces of the steel plates are processed; two steel plates that are required to be welded are vertically fixed through a fixing rack, and welded grooves of the steel plates are correspondingly arranged; welded positions of the steel plates are preheated; one side of each welded steel plate is subjected to tungsten inert gas shielded welding through welding wires that are made of a material that is identical to that of the steel plates, electric arcs move from top to bottom along the grooves, single-channel double-layer welding is applied, and after welding is finished, the same operation is performed on the other side of each steel plate. According to the tungsten inert gas shielded welding process of the 3mm-thickness steel plates, welded parts are welded through tungsten inert gas shielded welding, double-side vertical position welding is applied during welding, molten pool metal and molten slag are easy to separate, slag inclusion is not prone to occur, the welding effects are good, the welding is firm, the defect rate is low, surrounding air can be effectively isolated by argon, the electric arcs can automatically remove oxidation films of surfaces of workpieces in the welding process, and welding qualities are 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 3mm 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 3mm 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 3mm steel plate material, is characterized in that, comprise the following steps:
