Common problems, causes and solutions of high frequency welding

Common problems, causes and solutions of high frequency welding ⑴ Weak welding, desoldering, cold folding; Reason: The output power and pressure are too small. Solution: 1 adjust the power; 2 adjust the extrusion force. ⑵ There are ripples on both sides of the weld; Reason: The opening angle is too large. Solution: 1 adjust the position of the guide roller; 2 adjust the solid bending section; 3 increase the welding speed. ⑶The weld has deep pits and pinholes; Reason: Overburning occurred. Solution: 1 adjust the position of the guide roller and increase the opening angle; 2 adjust the power; 3 increase the welding speed. ⑷The weld burr is too high; Reason: The heat affected zone is too wide. Solution: 1 increase the welding speed; 2 adjust the power. ⑸ Slag inclusion; Reason: The input power is too large and the welding speed is too slow. Solution: 1 adjust the power; 2 increase the welding speed. ⑹External cracks in the weld; Reason: The quality of the base metal is not good; it is subjected to too much squeezing force. Solution: 1 guarantee the material; 2 adjust the extrusion force. ⑺Wrong welding, lap welding Reason: Poor molding accuracy. Solution: Adjust the forming mold roll of the unit. Post time: Nov-28-2023
