Continous Welding
_____________________________________________________________________________________________
Problem
Seal not meeting strength requirements.
Probable Cause Solution
Material traveling too quickly. Decrease speed.
Not enough horn amplitude. Increase booster ratio.
Inconsistent blends of synthetic material. Evaluate material.
_____________________________________________________________________________________________
Problem
Inconsistent welding.
Probable Cause Solution
Nonuniform amplitude horn. Have horn analyzed for amplitude uniformity.
Variations in anvil (xture). Check xture design and dimensions.
Inconsistency of material. Evaluate material.
_____________________________________________________________________________________________
Problem
Seal area too great, causing ash.
Probable Cause Solution
Material traveling too slow. Increase speed.
Too much amplitude. Reduce booster ratio.
Excessive air pressure. Reduce air pressure.
_____________________________________________________________________________________________
Problem
Transducer and/or horn heating up.
Probable Cause Solution
Not enough air ow to dissipate Continuous duty applications requires
heat buildup cooling air (refrigerated air, in some
applications). Supply air to the stack interfaces and the horn tips.
