Description
Technical field
The present invention relates to a kind of stainless steel silk production technology, especially relate to a kind of production technology of welding rod stainless steel silk,
Belong to stainless steel silk technical field.
Background technology
Welding rod is welding materials the most conventional, conventional welding rod by core wire and coating two parts composition metal core wire outside
Wrap coating (coating), welding rod species is different, core wire is also different；Core wire is the metal-cored of welding rod, and the composition of core wire is straight
Connect the composition affecting weld metal and performance, core wire is usually a steel wire with certain length and diameter.
During welding, core wire has two effects：One is conduction welding current, produces electric arc and converts electrical current into into heat energy, two are
Core wire fusing itself forms weld seam as filler metal with the fusion of liquid base metals；During welding rod welding, core wire metal becomes whole
A part for individual weld metal, so the chemical composition of core wire, directly affects the quality of weld seam.
Stainless steel electrode can be divided into straight-chromiun stainless steel welding rod and chromium nickel stainless steel welding rod, and straight-chromiun stainless steel has certain anti-corrosion
（Oxidizing acid, organic acid, cavitation erosion）Heat-resisting and corrosion resisting property, is typically chosen as the equipment and materials such as power station, chemical industry, oil.But chromium
Rustless steel generally solderability poor it should be noted that welding procedure, heat treatment condition and select suitable welding rod.Chromium nickel is not
Rust steel electrode has good corrosion resistance and non-oxidizability, is widely used in chemical industry, chemical fertilizer, oil, medical machinery manufacture.It is anti-
Only produce corrosion between eyeball due to heating, welding current should not be too big, and less 20% about than carbon steel, electric arc should not mistake
Long, interlayer rapid cooling, it is advisable with string(er) bead.
Because the resistance value of the core wire of stainless steel electrode is bigger than carbon steel, heat conductivity is poorer than carbon steel, and the table of rustless steel molten drop
Face tension force is big, thus its molten drop is based on bulky grain short circuiting transfer in welding process, so the prolongation with weld interval
Raise with temperature, welding technological properties will be produced not ideal enough；General stainless steel electrode in welding process, electrode coating
Rubescent, the burn-off rate of welding rod accelerates suddenly, and the droplet transfer is wayward, and electric arc moves swiftly, and appearance of weld is deteriorated；Rubescent weldering
After bar cooling, coating cracking, causes welding rod cannot be continuing with causing very big waste, and stainless steel electrode price is higher, therefore drops
Its use cost low is higher；
It is thus desirable to producing the covered electrode with high adhesion, so that coating is preferably bonded on stainless steel silk, remove
The composition improving coating outer in addition it is also necessary to so that the stainless steel silk drawing is more uniformly distributed in the preparation process of stainless steel silk, surface
Consistent degree is more uniformly distributed, so that it can be more tight when coating is combined；But, the stainless steel silk production process of routine
In apply due to lacking constant tension force, therefore its be subject to different pull power after will lead to whole piece steel wire various pieces stress not
Unanimously, lead to its uniformity poor, affect the concordance after it is combined with coating.
