USB data line is a common wire in life. All↓¥≈ users know is that USB data ¶€line has the function of chargiδσ'ng, but they do not know the key points in t£↓>​he process of USB data‌≤≤ line processing. Then jiefexin wir≤♣e processing plant w×↑ill introduce to you the points needing attentiδ©on in the process of U£©SB data line welding.

Length of arc

The arc length is related to the type ¶∏σof electrode coating and the thickness↑× of coating. Short arcs should be used as '™ ™far as possible, since the arc length may cau → $se porosity,

Short arc can avoid harmf☆&ul gases in the atmos‍≠↔phere, such as O2 and N2×↔, from invading the weld l, forming oxide and★‌✘ other undesirable impurities and affecting→↕★ the quality of the weld.

Ii. Welding speed

Maintain the appropriate welding sp •¶≠eed, slag can cover the pool. All kinds ‌÷<↔of impurities and gases in the pool can be f≤£♣ully surfaced to avoidΩ↕∑ slag inclusion and porosit'★βy. During welding, if the rod mo↕≈ ©ving speed is too fas↕>$t, when the welding part is cooled,≥∞₹₩ the shrinkage stress will in≠€crease, resulting in cracks ↓←in the welding seam.

Three, welding wire selection points

The choice of welding wire sαε©​hould be d on the type of steel being weld♠←ed, the quality requirements of welding parts, we∏δ&σlding construction conditions∏✘€ (plate thickness, groo✔§ve shape, welding position, welding condition₩§♠s, post-welding heat✔®λ→ treatment and welding operation wait), cost and   other comprehensive consideration.

Four, the selection of weldiε₽≤ng wire to consider the order as follow$×α&s:

According to the structure of the™γφ steel welding wire selection.

(2) according to the qualit£©&∑y requirements of the ÷♥₩φwelded parts (especia¥♣<lly impact toughness) choose weldin×→ g wire and welding conditions, groove sha↕ pe, protective gas m±÷↓✔ixture ratio and other p♥₽∑rocess conditions, in orde ¥∑r to ensure the performan☆→↑∏ce of the welding joint on the premise →←€of the choice to achieve the ma"™ximum welding efficiency andδ∞• reduce the cost of welding materia€≤↕±ls.

(3) according to the site welding position correσ☆ sponds to the thicknes&♥s of the welding workpie←×ce plate to choose the diamΩ>∞δeter of the wire used, determine the ‍‌πΩcurrent value used, refer to the produc"•t introduction data and experien☆ ™ce of each production plant, choose suitaλ↕ble for the welding pos♥>ition and the use of cur€§rent wire brand. Weldin∏§‍♥g process performance includes arc stability, s≥↓©<plash particle size a★♦σnd quantity, slag removal, appearanc§₽€≤e and shape of welding seam, etc. For the we¥±lding of carbon steel and low all✘™¶oy steel (especially semi-automati∞ ≠>c welding), the welding &¥∏method and welding matε↑erial are mainly selected according ♥ ←to the welding performance.
