The QM Series Seamwelders produce very high quality welds that are generally no more than 10% thicker than the parent material. Welds can be made in less than 25 seconds using these welders, depending on strip size.

QMT AND QMM QUICKLAP SEAM WELDERS EXCLUSIVE FEATURES:

The QM Quicklap Seam Welder series includes two (2) machines, depending on your requirements. The QMT is used for higher speed applications and the QMM is used on heavier gage applications. The QM Series Seam Welder joins two (2) coil ends together by resistance welding two slightly overlapped strip ends. The QM Welder is designed for use on either start/stop or continuous lines such as:

The weld created by the QM series is an overlap resistance weld. The two coil ends are slightly overlapped and the weld wheels, one on the top and one on the bottom, roll across the overlapped ends to make the weld. Then hardened planish rolls, again one on the top and one on the bottom, follow the weld wheels, and the result is a very fast, flat, and strong weld. Welds created using this machine are usually nearly as strong as the parent material. An optional induction annealer can also be placed on the machine to post-anneal the weld during the same pass as welding and planishing.

PRODUCT RANGE
The QMT and QMM can shear, weld, and planish material ranging from about 0.1mm (0.004") up to about 3.0mm (0.125") thick, and as wide as necessary. Recent machines have been used for strip up to 1,900mm (76") wide. Any weldable material can be joined on these machines.
