Abstract
A kind of upright downward manual electric arc welding welding material.The present invention is a lime-titania type commonly used in a kind of welding, can be the vertical doconward weld rod that uses under the plus or minus situation at the θ angle.Its main material and percentage by weight thereof are: rutile 10 to 40; Titanium dioxide 3 to 15; Marble 10 to 30, ilmenite 10 to 20, cellulose 3 to 10; With ferrotianium and mid-carbon fe-mn is main deoxidier.Slag and molten iron are not dropped down in the present invention when standing weldering downwards; Deposition rate＞95% does not have the welding defective, the quality of weld joint height, and more general common lime-titania type electrode has higher impact value α k 〉=18Kg-m/cm
2High efficiency.
Description
The invention belongs to upright downward manual electric arc welding welding material.
The employed welding rod of prior art is most to be the all-position welding material, can only adopt upright upwards welding in the vertical position of welding.Cause quality of weld joint not high, inefficiency, energy loss is big.Now existing low hydrogen type vertical doconward weld rod and cellulose vertical doconward weld rod.But lime-titania type welding rod commonly used does not also have vertical doconward weld rod in general Welding Structure.The low hydrogen type and the cellulose type vertical doconward weld rod of particularly passing by to develop all need found the angle that keeps an electric arc top-blown bath downwards when welding
See accompanying drawing, caused certain difficulty to production application.
The present invention be for create a kind of lime-titania type De And can
The angle is the vertical doconward weld rod that uses under the plus or minus situation.
The present invention is by rutile; Titanium dioxide; Marble; Ilmenite; Cellulose and other auxiliary material are made.The proportioning of main material is by weight percentage: rutile 10 to 40; Titanium dioxide 3 to 15; Marble 10 to 30; Ilmenite 10 to 20; Cellulose 3 to 10; Its auxiliary material are white clay; Ferrotianium; Magnesia; Mid-carbon fe-mn; Iron powder and waterglass.
The present invention uses ferrotianium and mid-carbon fe-mn to be the main deoxidier in the welding rod, except obtaining upright preferably downward welding performance, also makes weld metal have higher impact flexibility, its value
〉=18kg-m/cm
2
Slag is not dropped down in the present invention when standing weldering downwards; Do not drop down molten iron; Moulding is attractive in appearance; Deposition rate＞95%; There is not the welding defective.The quality of weld joint height, more general common lime-titania type electrode has higher impact value
〉=18kg-m/cm
2, high efficiency.Its strength grade is equivalent to GB knot 422.It is applicable to the welding of all common welded verticals position of welding.And other some have the welding of the vertical position of welding of high requirement.
Claims (2)
1, a kind of upright downward manual electric arc welding welding material, comprise rutile, titanium dioxide, marble, ilmenite, cellulose, auxiliary material: white clay, magnesia, ferrotianium, mid-carbon fe-mn, iron powder and waterglass, it is characterized in that proportion of raw materials is that rutile is 10 to 40 by weight percentage, titanium dioxide is 3 to 15; Marble is 10 to 30; Ilmenite is 10 to 20; Cellulose 3 to 10.
2, a kind of according to the said lime-titania type vertical downward electrode of claim 1, it is characterized in that with ferrotianium and mid-carbon fe-mn be main deoxidier in the welding rod.
