Friction Weld Seal Control

Friction welding, also known as friction joint weld, fuses the two ends of strapping together by a high-frequency movement that generates heat that melts the two surfaces. After this, the two straps are mechanically pressed together to form the seal. As the standard in the industry, friction welds are used by all hand strapping tools and most semi-automatic and automatic strapping machines.

Correct Seal

The seal must be completely welded over the whole width of the strap on a length of ca. 19 mm. Minor quantities of fused plastic may overflow on the sides.

Welding Time Too Short

If the welding time is too short, the plastic strapping will not be welded over the whole width of the strap, making the sealing insufficient. Straps with insufficient seal strength must be removed from the package and resealed.

Welding Time Too Long

If the welding time is too long, the straps become overheated and the fused plastic will overflow on both sides of the straps. Straps with insufficient seal strength must be removed from the package and correctly sealed.
