How to weld the pre-painted galvanized sheet after it is disconnected?
The processing method of the color-coated boards needs more and more measures.
It is necessary to increase the number of technical personnel.
For example, in order to achieve the purpose of corrosion, it generally states that the concentration of the corrosion inhibitor increases with the increase of the corrosion inhibitor.
When the concentration reaches a certain value, the concentration of the corrosion inhibitor increases, but the corrosion inhibitor concentration reduces.
How can we achieve the goal?
The main difference of the color-coated stainless steel plate is the quality of the nickel heat pipe.
Nickel is an excellent corrosion-resistant material.
After the combination of stainless steel and chromium alloy, corrosion resistance and process performance improved.
However, in order to obtain a pure austenite structure, the nickel content of carbon-nickel steel reaches 24%.
Only when the nickel content is 27%, the corrosion resistance of the steel in certain media cannot be significantly changed.
The corrosion resistance of pre-painted panels has undergone major changes. For its alloy composition and internal structure, chromium plays a major role.
Chromium has the chemical stability that can form.
It is a passivation film on the surface of the steel to make it elastic with biology, prevent a metal collision, and increase the corrosion resistance of the steel plate.
The price of a 310S painted board has two characteristics: Simple and almost no area, which allows users to apply it more seriously than usual.
The price increase of many materials exceeds 310 seconds for the arc starting of the color-welded coated plate and the accelerated transformation.
The welding of the materials is complete to ensure good fusion and prevent incomplete penetration and slag inclusion. And other defects.
If the positioning weld of the color-coated board appears, it is necessary to remove the weld at the seam, and then reposition the weld.
After spot welding, if the flush joints are uneven, the next step should be performed before the formal welding.
If necessary, increase the length of the tack weld, the method of tack weld, or take treatment measures.
