High frequency welding hollow aluminum glass strip

With the development of three important industries of aviation, construction and automobile, the demand data characteristics have the common properties of aluminum and its alloys, which is greatly beneficial to the production and use of aluminum. Nowadays, the application of high-frequency welding hollow aluminum glass strips is very extensive. The use of high-frequency welded hollow aluminum glass strips can not avoid problems. Let us look at them:
 
Causes and solutions for common problems of high frequency welding aluminum strips:
 
1. Welding is not strong, desoldering, cold stacking.
 
  the reason:
 
(1) There is no match between output power, pressure and speed.
 
(2) The edge of the strip is damaged or there are other defects.
 
Solution: 1. Adjust the power; 2. Change the shape of the groove by thick material tube blank; 3. Adjust the pressing force; 4. Adjust the speed.
 
2. There are ripples on both sides of the weld.
 
Reason: The angle of convergence is too large.
 
Solution: (1) adjust the position of the guide roller; (2) adjust the solid bending forming section; (3) increase the welding speed.
 
3. The weld has deep pits and pinholes.
 
Cause: There was a burn.
 
Solution: (1) adjust the position of the guide roller, add the assembly angle; (2) adjust the power; (3) increase the welding speed.
 
4. Weld burrs are too high.
 
Cause: The heat affected zone is too wide.
 
Solution: (1) increase the welding speed; (2) adjust the power.
 
5, slag inclusion.
 
Cause: The input power is too large and the welding speed is too slow.
 
Solution: (1) adjust the power; (2) increase the welding speed.
 
6. Cracks outside the weld.
 
Reason: The quality of the base metal is not good; it is subject to too much squeezing force.
 
Solution: (1) ensure the material; (2) adjust the pressing force.
 
The above is about the use of high-frequency welding hollow aluminum glass strips and solutions.
