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.
