As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
Comparing signature images from moment to moment in a weld provides a useful estimate of how stable the welding process is. [ 17 ] [ 18 ] "Through-the-arc" sensing, by comparing signature images when the physical parameters of the process change, leads to quantitative estimates—for example, of the position of the weld bead.

In 1984, the company developed a neodymium-doped yttrium aluminum garnet laser welder that allowed for more precise and micro welding, and this product line became a central component of the company's business, along with resistance welding. In 2006, the company developed the first Yb: fiber laser welder in Japan.
