The most significant development made in the manufacture of strong, high-quality plate heating elements is laser beam welding. All AXERO™ heating elements have laser beam edge welds and spot welds. The main benefits of this technology are as follows:

• The laser beam weld can be made in any diameter resulting in fewer, larger, and stronger welds.

• The laser beam weld has less energy input and a smaller heat affected zone.

• Heating elements can be visually inspected from both sides of the plate.

• Laser beam welding permits the manufacture of longer heating elements.
